I am using the Support Library to add a bottom bar similar to the material design one. The bottom bar works great but it seems that if I have the bar displayed, if I try to open any fragment from my custom adapter, the fragment does not open...or maybe it opens behind my main layout? I have no idea how to figure this out. Below is my code.
I've read more posts on SO and around the web and I think this is related to the fragment being properly loaded but below or next to the bottom bar...and that is why it isn't visible? Why does this happen? Is it because the bottom bar has a LinearLayout? I defined it as a menu so I'm not sure if I can control it being a LinearLayout....
Setting up the bottom bar, this method is called from the onCreate of my activity:
public void setupBottomToolbar(Bundle savedInstanceState) {
mBottomBar = BottomBar.attach(MainActivity.this, savedInstanceState);
mBottomBar.setItems(R.menu.bottombar_menu);
mBottomBar.setOnMenuTabClickListener(new OnMenuTabClickListener() {
#Override
public void onMenuTabSelected(#IdRes int menuItemId) {
if (menuItemId == R.id.toolbar_jobs) {
} else if (menuItemId == R.id.toolbar_messages) {
} else if (menuItemId == R.id.toolbar_recentJobs) {
} else if (menuItemId == R.id.toolbar_employerPools) {
}
}
#Override
public void onMenuTabReSelected(#IdRes int menuItemId) {
if (menuItemId == R.id.toolbar_jobs) {
// The user reselected item number one, scroll your content to top.
} else if (menuItemId == R.id.toolbar_messages) {
} else if (menuItemId == R.id.toolbar_employerPools) {
} else if (menuItemId == R.id.toolbar_recentJobs) {
}
}
});
// Setting colors for different tabs when there's more than three of them.
// You can set colors for tabs in three different ways as shown below.
mBottomBar.getBar().setBackgroundColor(getResources().getColor(R.color.laborswipe_darkgray));
mBottomBar.setActiveTabColor(getResources().getColor(R.color.laborswipe_lightgray));
// Make a Badge for the second tab, with red background color and a value of "13".
BottomBarBadge unreadMessages = mBottomBar.makeBadgeForTabAt(1, getResources().getColor(R.color.laborswipe_orange), 5);
// Control the badge's visibility
unreadMessages.show();
//unreadMessages.hide();
// Change the displayed count for this badge.
//unreadMessages.setCount(4);
// Change the show / hide animation duration.
unreadMessages.setAnimationDuration(200);
// If you want the badge be shown always after unselecting the tab that contains it.
unreadMessages.setAutoShowAfterUnSelection(true);
// If you don't want this badge to be hidden after selecting the tab contains it.
unreadMessages.setAutoShowAfterUnSelection(false);
}
In my adapter, I am trying to open the fragment when you click a button, like this:
holder.desc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(context, "Open Description", Toast.LENGTH_SHORT).show();
JobDescFragment firstFragment = new JobDescFragment();
((MainActivity)context).getSupportFragmentManager().beginTransaction()
.add(R.id.fragment_container, firstFragment).commit();
}
});
If I comment out the call to setupBottomToolbar() in my onCreate of the activity, the fragment opens up fine...but that means I don't have the bottom bar...
What am I missing? There has to be a way to use the bottom bar and also open a fragment?
Thanks!
EDIT:
Here is the top part of my activity.

When I use the bottom bar (not working- no fragment opened but toast displayed):
When I don't use the bottom bar (workin-fragment opened, background is green):
try to link a pic of problem and without problem(no bottombar) and since you are using merge the layout hierarchy will be laid off according to your activity's viewgroup(linear,relative) constraints(we don't know what they are like).
as you said when there is no bottombar ,you fragment displays perfectly though when the bottombar it there ,problem stats ,as per your log in fragment indicating that your fragment is loading perfectly even though when bottombar is visible mean fragment is there but is not visible ,seems like your fragment didn't get the appropriate space to get displayed.
other solution can be adding bottom bar to your fragment instead of activity to avoid any overlapping ,like
mBottomBar.attach(findViewById(R.id.fragmentContainer), savedInstanceState);
OK, I think the solution for this should be simple, from what I can see in your code, you are attaching the BottomBar to your activity, I think this is the problem. If you were to read the readme.md in the roughike/BottomBar github page you'd find this
Why is it overlapping my Navigation Drawer?
All you need to do is instead of attaching the BottomBar to your Activity, attach it to the view that has your content. For example, if your fragments are in a ViewGroup that has the id fragmentContainer, you would do something like this:
mBottomBar.attach(findViewById(R.id.fragmentContainer), savedInstanceState);
So, since navigation drawer works with transition a fragment in and out of view with animation, the same thing is happening when you are adding a new fragment to your activity.
The Solution
From what I can see in your code, your fragment container id is this: fragment_container in your activity layout. So according to the documentation you'd just need to do attach your bottomBar to the fragment_container instead of MainActivity.this
mBottomBar.attach(findViewById(R.id.fragment_container), savedInstanceState);
If the above doesn't work try this
What you'd need to do is add an extra FrameLayout to hold your bottombar, which has a transparent background, but is on top of your fragment.
So change your main_activity layout to
<merge
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<com.lorentzos.flingswipe.SwipeFlingAdapterView
android:id="#+id/frame"
android:background="#color/laborswipe_lightgray"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:context=".MainActivity"
android:layout_gravity="top" />
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/holder_bottombar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent"/>
</merge>
Now in the code instead of attaching the bottom bar to mainactivity, just attach it to the holder like so
mBottomBar.attach(findViewById(R.id.holder_bottombar), savedInstanceState);

I want to add items to RecyclerView when I click the "Add" button
This currently works but only once , meaning if I click the Add button the first time, the item is added and visible, but after that, nothing is added.
Here is my code for RecyclerView Adapter
public class Adapter extends RecyclerView.Adapter<Adapter.myViewHolder> {
List<Integer> listItem;
public Adapter(List<Integer> passedListItem){
this.listItem = passedListItem;
}
#Override
public myViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.recyclerview_layout, parent, false);
myViewHolder holder = new myViewHolder(itemView);
return holder;
}
#Override
public void onBindViewHolder(myViewHolder holder, int position) {
int itemNumber = position+1;
holder.itemTextView.setText("Item Number " + itemNumber + ": " + listItem.get(position));
}
#Override
public int getItemCount() {
return listItem.size();
}
public class myViewHolder extends RecyclerView.ViewHolder {
TextView itemTextView;
public myViewHolder(View view){
super(view);
itemTextView = view.findViewById(R.id.tv_itemTextView);
}
}
}
Here's my MainActivity
public class MainActivity extends AppCompatActivity {
List<Integer> itemList = new ArrayList<>();
EditText itemEditText;
RecyclerView recyclerView;
Adapter rvAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView)findViewById(R.id.rv_itemsRecyclerView);
itemEditText = (EditText)findViewById(R.id.et_editText);
//Setting the layout and Adapter for RecyclerView
recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext()));
rvAdapter = new Adapter(itemList);
recyclerView.setAdapter(rvAdapter);
}
//Click listener for "Add" Button
public void onAddButtonClicked(View view) {
try {
int IntegerFormat = Integer.valueOf(itemEditText.getText().toString());
itemList.add(IntegerFormat);
rvAdapter.notifyItemInserted(itemList.size() - 1);
itemEditText.setText("");
} catch(NumberFormatException e) {
Toast.makeText(getApplicationContext(), "The field is empty",
Toast.LENGTH_SHORT).show();
}
}
}
When i click the Add button, the first item is added and is visible, but when I click the Add button second time, nothing happens.
Solved
EDIT: Apparently, my Recycler view layout had its width and height set to match_parent instead of wrap_content, so the second item was getting added after clicking the button but it was added way way below. And I was stupid enough to not even try to scroll down. Everything was just working fine but I was ignorent.
I just checked your code and it is working fine. The mistake is in the recyclerview_layout.xml file which you havent posted. What you have is this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/tv_itemTextView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="TextView" />
</LinearLayout>
Please change this to:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/tv_itemTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>
Your first list item is filling the entire recycler view because your linear layout has android:layout_height="match_parent" instead of android:layout_height="wrap_content" so the first item is hiding the other items but they are there in the adapter. You can confirm this by logging in logcat.

After few attempts which I've made by myself, I've asked uncle Google about your problem. Do you know, what he said?
ListView aren't able to handle EditText view well. If many people couldn't resolve this issue before, maybe you will consider some 'workaround' like this desribed HERE. It is an answer to other issue, but probably even if you will fix above problem, you will meet this one.
In brief #Andrew recommends to use ScrollLayout with simple LinearLayout inside instead of ListView. In onCreate method he inflates the View used for list items and add it to LinearLayout, and store this in ArrayList as well, to save data to every view later.
I know it isn't solution for your problem, but maybe it let you a lot of time, which you will spend looking for any reasonable solution.
Edit
It is funny. Inspired by #Rishabh Srivastava link I've tried to find some solution (I know, I'm a little bit stubborn).
I've create adapter layout - RelativeLayout, which is fully filled by Button and above it (I mean literally above it - in Z axis) I've placed EditText view. I thought that edittext will handle click on it and button will handle clicks outside of edittext view. Unfortunately 'click' event propagate through all of views - so by clicking on edittext, we will click on button as well.
I thought I am smarter than everybody so I used OnTouchListener - we can handle single 'touch' event and return true value, as information to OS that we handle it.
And you know what? I've met problem exactly the same like desribed in above link:
When I click on an EditText, the virtual keyboard shows itself, but the EditText loses focus and I have to click the EditText again.
I hope you don't want lost your time any more;)
first of all, thank you everyone!
I tried all of the answer, but it didn't work...:(
Focusable EditText in the ListView and onItemClick
it works for me

Here is my implementation.. hope it help
FIRST, this POST is concept.
SECOND, this is also the KEY one.
FINALLY, Here is combination of all answer in one place
BASE ACTIVITY
This is a base activity for all other activity
You can extends Activity or FragmentActivity or etc. base on your requirement.
Navigation Drawer setup here for one time.
public class BaseActivity extends FragmentActivity {
protected DrawerLayout mDrawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);

BASE ACTIVITY XML
This xml layout is for Navigation Drawer
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:scrollingCache="false"
android:background="#drawable/drawer_bg"
android:divider="#null"
android:choiceMode="singleChoice"/>
</android.support.v4.widget.DrawerLayout>
ALL OTHERS ACTIVITY
Other Activity just extends BaseActivity and define code as below.
The Navigation Drawer will appear for particular activity.
mDrawer is form BaseActivity. it's a protected variable.
public class Screen1 extends BaseActivity
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//inflate your activity layout here!
View contentView = inflater.inflate(R.layout.screen1, null, false);
mDrawer.addView(contentView, 0);
//Do the rest as you want for each activity
}
SCREEN 1 XML SAMPLE
Design as you wish it each activity. no more Navigation Drawer Layout !
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
NOTE
In this implementation, The Navigation Drawer doesn't bind with Action Bar. If you wish to do that do it in BaseActivity.Also, This guide is not cover all requirement. It's just a sample.
in onCreate of TutorialActivity don't call setContentView instead do this:
#Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
LayoutInflater inflater = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View contentView = inflater.inflate(R.layout.help, null, false);
mDrawer.addView(contentView, 0);
}
make mDrawer in MainActivity protected. and in R.layout.activity_main_drawer just keep drawer tag and the element with gravity left(or right).
I made a BaseActivity activity which extends SherlockActivity (or ActionBarActivity if is your case)
public class BaseActivity extends SherlockActivity
Then, make all your activities extends BaseActivity, like:
public class GlossaryActivity extends BaseActivity
Later, you must replace the activity layout with the one that correspond to your activity, I made a method in BaseActivity like that:
protected void replaceContentLayout(int sourceId, int destinationId) {
View contentLayout = findViewById(destinationId);
ViewGroup parent = (ViewGroup) contentLayout.getParent();
int index = parent.indexOfChild(contentLayout);
parent.removeView(contentLayout);
contentLayout = getLayoutInflater().inflate(sourceId, parent, false);
parent.addView(contentLayout, index);
}
I called this method on the onCreate method in each activity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.replaceContentLayout(R.layout.activity_glossary, super.CONTENT_LAYOUT_ID);
}
super.CONTENT_LAYOUT_ID is the FrameLayout of the BaseActivity, and other param is the layout you want replace with
You omitted the #Override from your derived class onCreate.
UPDATE: I'm not sure what the effects are of calling setContentView twice but that could be the problem. Separate out the code that sets up the drawer, and call that from both of the onCreate methods.
I had this problem too. This is my implementation:
activity_main.xml - the child at index 1 in the CoordinatorLayout is the content_main.xml, this I can change in code.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

I've created a class that uses inflates the others activities UI:
public class MyLayoutInflater {
public void inflate(Activity activity, int LayoutResource, android.app.ActionBar getSupportActionBar, Intent getIntent){
CoordinatorLayout coordinatorLayout = (CoordinatorLayout) activity.findViewById(R.id.coordinator);
android.view.LayoutInflater inflater = (android.view.LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View contentView = inflater.inflate(LayoutResource, null, false);
//change i so that it suits the child number in you coordinator layout
int i = 1;
coordinatorLayout.removeViewAt(i);
coordinatorLayout.addView(contentView, i);
getSupportActionBar.setTitle(actionBarTitle);
}
public void inflate(Activity activity, int LayoutResource, android.support.v7.app.ActionBar getActionBar, String actionBarTitle){
CoordinatorLayout coordinatorLayout = (CoordinatorLayout) activity.findViewById(R.id.coordinator);
android.view.LayoutInflater inflater = (android.view.LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View contentView = inflater.inflate(LayoutResource, null, false);
//change i so that it suits the child number in you coordinator layout
int i = 1;
coordinatorLayout.removeViewAt(i);
coordinatorLayout.addView(contentView, i);
getActionBar.setTitle(actionBarTitle);
}
}
Now on the other activities all you have to do is extend the MainActivity and call this method and give it the necessary parameters:
public class AnotherActivity extends MainActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new MyLayoutInflater().inflate(this,R.layout.content_activity_another, getSupportActionBar(), getIntent());
}
}
Ok here is hacky way to do this, I use it only for special kind of debug build to set properties of views in realtime (design tool).
It has advantage that you can use your child activities as usual without, special behavior that is required in different answers.
so in BaseActvity you can add:
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// WARNING: Hacky, use carefully!!!
ViewGroup androidBaseView = (ViewGroup) findViewById(android.R.id.content);
//this one in what child activity has just set in setContentView()
ViewGroup childContent = (ViewGroup) androidBaseView.getChildAt(0);
View drawerView = LayoutInflater.from(this)
.inflate(R.layout.base_activity_drawer, androidBaseView, false);
FrameLayout frameLayout = (FrameLayout) drawerView.findViewById(R.id.content);
androidBaseView.removeView(childContent);
frameLayout.addView(childContent);
androidBaseView.addView(drawerView);
}
and xml for drawer is just:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/nav_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<LinearLayout
android:id="#+id/drawer_for_components"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="end"
android:orientation="vertical"
android:fitsSystemWindows="true"
/>
</android.support.v4.widget.DrawerLayout>
Here is a simple and fast way to do it in android studio:
Create a new activity (Navigation drawer activity) from the gallery, and name it whatever you want, android studio will create everything for you (the class and the xml files that you can customize it later)
In other activities you should extend your Navigation drawer activity, and make sure these other activities has "no action bar" in the manifests file (android:theme="#style/AppTheme.NoActionBar")
You should modify your other activities as follows:
public class Mainactivity extends NavActivity
{
super.onCreate(savedInstanceState);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//inflate your activity layout here!
View contentView = inflater.inflate(R.layout.activity_main, null, false);
drawer.addView(contentView, 0);
}
Note: the mainactivity will extend the action bar of the NavActivity, the NavActivity has a full functional action bar that will call the navigation drawer
I hope it will work with you
Nowadays you should use Single-Activity App Architecture (source).
Then simple add Navigation Drawer to Main Activity
you can simply use <include/>
By creating a nav drawer
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
and then include the layout in it
<include
layout="#layout/activity_accounts"
android:layout_width="match_parent"
android:layout_height="match_parent" />
in your main activity make setContentView(R.layout.your_drawer_activity)
take note that if you use this method you have to create a nav drawer layout for every activity you have, unless you found a way to do includes programmatically.
OnClick doesn't work. Nothing happens after clicking on layout. It seems like it is clickable, because layout changes its color, but new layout doesn't open.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/window"
android:layout_width="295dp"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/editborder"
android:clickable="true"
android:onClick="openBigImage">
Here is more code for Main Activity:
public class MyMapActivity extends FragmentActivity implements LocationListener
{
private Marker marker;
private Hashtable<String, String> markers;
private ImageLoader imageLoader;
private DisplayImageOptions options;
private GoogleMap map;
private ListView mainListView ;
private ArrayAdapter<String> listAdapter ;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_map);
// Look up the AdView as a resource and load a request.
//AdView adView = (AdView)this.findViewById(R.id.adView);
//adView.loadAd(new AdRequest());
// Getting Google Play availability status
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
// Showing status
if(status!=ConnectionResult.SUCCESS)
{ // Google Play Services are not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();
}
else
{// Google Play Services are available
// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment mapFragment = (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);
if (savedInstanceState == null) {
// First incarnation of this activity.
mapFragment.setRetainInstance(true);
}
else
{
// Reincarnated activity. The obtained map is the same map instance in the previous
// activity life cycle. There is no need to reinitialize it.
map = mapFragment.getMap();
}
setUpMapIfNeeded();
}
}
#Override
protected void onResume()
{
super.onResume();
setUpMapIfNeeded();
}
public void openBigImage(View v)
{
setContentView(R.layout.bigpicture);
}
bigpicture.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/bigpicture"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:orientation="vertical">
<fragment
android:id="#+id/minimap"
android:layout_width="200px"
android:layout_height="200px"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
class="com.google.android.gms.maps.SupportMapFragment" />
<ImageView
android:id="#+id/badge"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:adjustViewBounds="true" />
</RelativeLayout>
Calling setContentView() multiple times worked in other cases, like menu items "about", "settings" etc.
Tried to make without setContentView. I've put new Layout to the main.xml and made visibility GONE. OnClick method should change visibility to visible, but again nothing happens.
Logcat says "11-25 13:47:28.638: D/GestureDetector(3156): [Surface Touch Event] mSweepDown False, mLRSDCnt : -1 mTouchCnt : 2 mFalseSizeCnt:0" when i'm clicking on linear layout.
Paul,
One thing is close the linear layout with /> .I am assuming that you have followed the map tutorials link and passed all the manifest permissions and other requirements. You might have some reasons to use px. Check if map is being created. Also give some height and background color to your badge image and see if something happens.
I tested your code without map fragment and it worked fine.
Can you post the error log ?
Found. It is a click on InfoWindow, so we should implement onInfoWindowClick.
But first we must add map.setOnInfoWindowClickListener(this); in main activity. Main activity must implement OnInfoWindowClickListener.
I've added new LinearLayout to the main.xml, made it invisible.
Here's code for onInfoWindowClick:
#Override
public void onInfoWindowClick(Marker marker) {
LinearLayout secondLL = (LinearLayout) findViewById(R.id.bigpicture);
int visibility = secondLL.getVisibility();
if(visibility == View.GONE)
{
secondLL.setVisibility(View.VISIBLE);
}
}
I think you can't use onClick attribute.
You have to use setOnClickListener() like that :
LinearLayout layout = (LinearLayout )findViewById(R.id.window);
layout .setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
YourActivity.this.setContentView(R.layout.bigpicture);
}
});
I want the onclick method to communicate with the other views in my layout. I am getting a NullPointerException when attempting to do so. I think I may be doing it wrong.
My getView method is below:
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
ViewHolder holder;
final int p =position;
if (v == null) {
LayoutInflater vi = (LayoutInflater) _c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.menuitemrow, null);
holder = new ViewHolder();
holder.image = (ImageView) v.findViewById(R.id.MIR_itemImage);holder.image.setTag(position);
holder.itemName = (TextView)v.findViewById(R.id.MIR_itemName);holder.itemName.setTag(position);
holder.itemPrice = (TextView)v.findViewById(R.id.MIR_itemPrice);holder.itemPrice.setTag(position);
holder.itemOther = (TextView)v.findViewById(R.id.MIR_itemOther);holder.itemOther.setTag(position);
holder.details = (Button) v.findViewById(R.id.MIR_detailsbtn);holder.details.setTag(position);
holder.qAdd = (Button) v.findViewById(R.id.MIR_qaddbtn);holder.qAdd.setTag(position);
v.setTag(holder);
} else
holder = (ViewHolder) v.getTag();
MenuItemDetail mid = _data.get(position);
holder.image.setImageResource(mid.icon);
holder.itemName.setText(mid.itemName);
holder.itemPrice.setText("Price: $"+mid.itemPrice);
holder.itemOther.setText(mid.itemOther);
//set click listeners
holder.details.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
m =_data.get(p);
s = m.getItemName();
Toast.makeText(_c, "clicked details"+p+" "+s, Toast.LENGTH_SHORT).show();
}
});
holder.qAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(_c, "clicked quick add "+p, Toast.LENGTH_SHORT).show();
TextView btnUpdate = (TextView) v.findViewById(R.id.CBV_textview2);
//btnUpdate.setTag(1);
//btnUpdate.setText(btnUpdate.getTag().toString());
btnUpdate.setText("b");
}
});
return v;
}
as you can see I am just assigning a number to the getTag just to pass it to the setText method. I have tried it commenting out the set and get, using just a String.
the problematic line is btnUpdate.setText("b");
Any ideas?
to summarize I am trying to access a TextView of a custom Button inside of a custom ListView from its customer adapter's getView method.
UPDATE for comment:
This is a Custom Listview being displayed with other buttons. I want the listview item (a button that is part of the custom ListView) when it is click to update the textview of a custom button I created that is displayed in the same acitivity as the custom list view.
The Layout is below:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/MI_backbutton"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_weight="1"
android:text="#string/back_list_categories"
android:textSize="#dimen/FontSize8" />
<ListView
android:id="#+id/menuList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="20" >
</ListView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_gravity="bottom"
android:layout_marginBottom="5dp"
android:layout_weight="1" >
<Button
android:id="#+id/button2"
style="#android:style/Widget.Button"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_gravity="bottom"
android:layout_weight="1"
android:text="#string/generalbutton" />
<include
android:id="#+id/MI_checkorder"
style="android:buttonStyle"
android:layout_width="wrap_content"
android:layout_height="50dp"
android:layout_gravity="bottom"
android:layout_marginTop="5dp"
android:layout_weight="1"
layout="#layout/custombtnview"
android:background="#style/AppTheme"
android:clickable="true"
android:focusable="true" />
</LinearLayout>
In the view I am referencing to get the Textview, the textview is not there. What is in that view is the MI_checkorder. I was thinking maybe this is why I am getting the NullPointerException for my btnUpdate. the textveiw CBV_textview2 is part of the view I created as a button(MI_checkorder).
I now have the button but I am unable to get the change to show on the UI. Here is the code I added:
public void onClick(View v) {
Toast.makeText(_c, "clicked quick add "+p, Toast.LENGTH_SHORT).show();
TextView btnUpdate = (TextView) inflateToEdit(_c, v).findViewById(R.id.CBV_textview2);
//btnUpdate.setTag(1);
//btnUpdate.setText(btnUpdate.getTag().toString());
btnUpdate.setText("b");
}
and this is the method I created in the custom adapter class.
public View inflateToEdit(Context c, View view){
View vw = view;
LayoutInflater vi = (LayoutInflater) _c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
return vi.inflate(R.layout.custombtnview, null);
}
It is updating the button's text but it is not showing on the UI. I do not think i can update the UI from this point in the code. I think I need to do it from the activity.
That's because findViewById called on a view looks for the child view of the given view.
findViewById doc
"Look for a child view with the given id. If this view has the given id, return this view."
From what I can see, CBV_textview2 is contained in the layout of the activity.
So, what you can do is to pass the activity to the adapter's constructor (I see you already have a _c member variable which I suppose is a Context, OR directly pass the CBV_textview2 itself (calling findViewById in the containing activty).
In both cases, you need to call the activity's findViewById which
"Finds a view that was identified by the id attribute from the XML that was processed in onCreate(Bundle)."
public class YourAdapter extends ArrayAdapter<String> {
private final Context context;
// blahblahblah
private final TextView mYourTextView;
public YourAdapter(Context context, String[] values, TextView btnUpdate) {
super(context, R.layout.rowlayout, values);
this.context = context;
this.values = values;
mYourTextView = btnUpdate;
}
....
#Override
public void onClick(View v) {
Toast.makeText(_c, "clicked quick add "+p, Toast.LENGTH_SHORT).show();
//mYourTextView.setTag(1);
//mYourTextView.setText(btnUpdate.getTag().toString());
mYourTextView.setText("b");
}
In your activity you should be able to get the TextView before calling the constructor.
