Why does my scrollview leave "shadows" behind?

Why does my scrollview leave "shadows" behind? - java

So I am developing an app that uses firebase to load a list of buses, and if they have arrived or not. I'm relatively new to this and am trying to use fragments. I can get the fragment to load in successfully with the list of buses, but when I scroll through them it leaves behind a copy of the items, as seen here:
When it loads
When I scroll
MainActivity:
public class MainActivity extends AppCompatActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setTitle(null);
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
BusFragment busFragment = new BusFragment();
transaction.add(R.id.buscontainer, busFragment);
transaction.commit();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}

For anyone here looking for an answer, the way I fixed the issue was changing the fragment additions to fragment replacements. For some reason it was adding the fragments twice, hence the "shadows". Replacing instead of adding ensured there was only one loaded and fixed the issue.

Screen turns background colour when clicking on EditText inside ExpandableListView

I've been struggling to figure out this weird bug for a day and a half. Whenever I click on an EditText that is a child of an ExpandableListView, the screen gets obscured such that the user is unable to see what is being typed, as shown in the gif below: \n
https://giant.gfycat.com/GenuineUnluckyHyrax.mp4
I started digging into the Hierarchy View to see what could be doing this, here is a screenshot of it:
https://i.imgur.com/B4kkHv7.png
To me it looks like the Toolbar up top is extending downwards to cover the screen, which is odd because it doesnt do that on other activities that contain EditText widgets. I've checked that parent views are using "wrap_content" for height instead of "match_parent" as well, except for my DrawerLayout which must match_parent. Below is the layout code for the activity:

I'm assuming that this is all due to the layouts, but here is the CustomExpandableListAdapter that I wrote for it just in case the answer lies in how the views are being inflated:

Any points or tips would be great. I think that this may be due to the number of views in my hierarchy (or at least a subissue of it), but I'm not sure and am relatively new to Android Development.
Thanks!

I solved the issue, simply adding android:windowSoftInputMode="adjustNothing|stateHidden" caused the ActionBar to not expand to 996px when the EditText gained focus

Can't enable contextual action mode with CustomAdapter<MyClass>

I'm trying to enable contextual action mode in a ListView with my custom adapter inherited from ArrayAdapter<MyClass>. And can't. Just nothing is happening on long click. Neither in UI, nor in logs.
When I use ArrayAdapter<String> everything's working right. What is my mistake, please explain me. Thanks in advance.
Here are my files.

How to add onClick event for individual cardview elements NOT in recyclerview in android?

I'm working an app that has a list of cardviews and I want each cardview to open a certain activity when tapped. I am not using any recyclerviews or adapters, I have just created a multiple cardview xml files and included them into my main xml in coordinatorlayout and collapsingtoolbarlayout. I have tried to create onClick event for individual cardviews but app keeps crashing.
Following is my main.xml code:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="250dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:fitsSystemWindows="true"
android:background="#drawable/pic3"
android:id="#+id/profile_id"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingTop="10dp">
<include layout="#layout/card_layout1" />
<include layout="#layout/card_layout6"/>
<include layout="#layout/card_layout4"/>
<include layout="#layout/card_layout5"/>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
One of my cardviews xml:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/thumbnail"
android:layout_width="match_parent"
android:layout_height="250dp"
android:layout_alignParentTop="true"
android:src="#drawable/categories"
android:layout_marginTop="15dp"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"/>
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/thumbnail"
android:maxLines="3"
android:padding="8dp"
android:text="Categories"
android:textColor="#color/white"
android:textSize="22dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/title"
android:maxLines="3"
android:padding="8dp"
android:text="Embedded systems is ba jksdhkah jksadh bdkbadkwuhs hfoh dn ajbd arh fbkjasd akuhwkjd nsajkbf a dsadjna hwd nlksn ahrja snasfb kjasba sna"
android:textColor="#color/white"
android:textSize="14dp" />
</RelativeLayout>
And my MainActivity.java:
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private CollapsingToolbarLayout collapsingToolbarLayout=null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbarLayout.setTitle(getResources().getString(R.string.user_name));
dynamicToolbarColor();
toolbarTextAppearance();
}
private void dynamicToolbarColor() {
Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.elec);
Palette.from(bitmap).generate(new Palette.PaletteAsyncListener() {
#Override
public void onGenerated(Palette palette) {
int mutedColor = palette.getMutedColor(ContextCompat.getColor(MainActivity.this, R.color.colorPrimary));
collapsingToolbarLayout.setContentScrimColor(mutedColor);
}
});
}
private void toolbarTextAppearance(){
collapsingToolbarLayout.setCollapsedTitleTextAppearance(R.style.collapsedbar);
collapsingToolbarLayout.setExpandedTitleTextAppearance(R.style.expandedappbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return super.onOptionsItemSelected(item);
}
#Override
public void onClick(View v) {
}
}
How can I implement onClick event for each of my cardviews without using recyclerview and adapters?

It's a bad practice. But you can set tag to all card views, find them in code and set click listener:
in you main.xml
...
<LinearLayout
android:id="#+id/cardsContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingTop="10dp">
<include layout="#layout/card_layout1" />
<include layout="#layout/card_layout6"/>
<include layout="#layout/card_layout4"/>
<include layout="#layout/card_layout5"/>
</LinearLayout>
...
all in you card layouts must have tag:
<android.support.v7.widget.CardView
android:tag="clickableCard"
...>
...
</android.support.v7.widget.CardView>
Than you need to find all views with thos tag clickableCard : (solution from here: Find all views with tag?)
private ArrayList<View> getViewsByTag(ViewGroup root, String tag){
ArrayList<View> views = new ArrayList<View>();
final int childCount = root.getChildCount();
for (int i = 0; i < childCount; i++) {
final View child = root.getChildAt(i);
if (child instanceof ViewGroup) {
views.addAll(getViewsByTag((ViewGroup) child, tag));
}
final Object tagObj = child.getTag();
if (tagObj != null && tagObj.equals(tag)) {
views.add(child);
}
}
return views;
}
in you MainActivity.java in the end of onCreate method you need to:
ArrayList<View> clickableViews = getViewsByTag(findViewById(R.id.cardsContainer), "clickableCard");
for (int i = 0; i < clickableViews.size(); i++) {
final Integer viewIndex = i;
View cardView = clickableViews.get(i);
cardView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (viewIndex == 0) {
// do work with first card
}
else if (viewIndex == 1) {
// do work with second card
}
...
}
});
}

Activity is hidden by fragment, it is not useable

i have builded an app that works perfectly on android with api higer than 21. The problem is that this instruction of my code:
mFragmentTransaction.replace(R.id.content_frame, new TabFragment()).commit();
Works in different way on API less then 21.
On Api less then 21 the new fragment hide the previus activity, so that i can't click on my Floating Action Button.
Here are two images that explain in abetter way my problem.
API HIGER THAN 21
API LESS THAN 21
So my question is: How can i have the same result in API less then 21 that i have on API Higer then 21?
Here is the affected part of the Main Activity Code:
public class MainActivity extends AppCompatActivity {
public static AppDataBase appDataBase;
public static UserDataBase userDataBase;
static FragmentManager mFragmentManager;
static FragmentTransaction mFragmentTransaction;
private DrawerLayout myDrawerLayout;
final String TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE = "Add a console!";
TextView currentConsole;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
appDataBase = new AppDataBase(this);
userDataBase = new UserDataBase(this);
myDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
currentConsole = (TextView) findViewById(R.id.txt_Mainactvt_currentConsole);
currentConsole.setText(TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE);
tabLayoutManagement();
floatingActionButtonManagement();
leftDrawerMenuManagement();
rigthDrawerMenuManagement();
populateMyConsole();
}
void tabLayoutManagement() {
mFragmentManager = getSupportFragmentManager();
mFragmentTransaction = mFragmentManager.beginTransaction();
mFragmentTransaction.replace(R.id.content_frame, new TabFragment()).commit();
}
// Floating Action Button
private void floatingActionButtonManagement() {
FloatingActionButton fab_addGame = (FloatingActionButton)findViewById(R.id.fab_AddGame);
fab_addGame.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
/*
The currentConsole TextView is used to show at the user wich console is selected.
We use it to have a strng that conteins the selected console.
Call the method that manage the click event of the FloatingActionButton. We pass the console name.
*/
String currentConsoleName = currentConsole.getText().toString();
floatingActionButtonClickEvent(currentConsoleName);
}
});
}
private void floatingActionButtonClickEvent(String currentConsoleName) {
/*
Check if user have added a console. If he did start a menu for adding games, else start an
error message
*/
if (!currentConsoleName.equals(TXT_MAINACTVT_USER_HAVE_NOT_ADDED_CONSOLE)) {
popUpViewAddGameBuild(currentConsoleName);
}
else
mySimpleAlertDialogMethod("Attention!", "Before you enter game, you must enter a console.", true, true);
}
private void popUpViewAddGameBuild(String currentConsoleName) {
/*
Build the view that show the menu for adding games.
*/
LayoutInflater inflater = this.getLayoutInflater();
View popupView = inflater.inflate(R.layout.popupview_addgame, null);
PopupWindow popupWindow = new PopupWindow(
popupView,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT);
popupWindow.setInputMethodMode(PopupWindow.INPUT_METHOD_NEEDED);
popupWindow.setFocusable(true);
popupWindow.showAtLocation(popupView, 0, 0, 0);
}
Here is the TabLayout Class:
public class TabFragment extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View x = inflater.inflate(R.layout.tab_layout, null);
tabLayout = (TabLayout) x.findViewById(R.id.tabs);
viewPager = (ViewPager) x.findViewById(R.id.viewpager);
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
tabLayout.post(new Runnable() {
#Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
return x;
}
public class MyAdapter extends FragmentPagerAdapter {
public int position;
public MyAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
switch (position){
case 0 :
return new DesireFragment();
case 1 :
return new BuyedFragment();
case 2 :
return new StartedFragment();
case 3 :
return new FinishedFragment();
case 4 :
return new AllTrophiesFragment();
}
return null;
}
#Override
public int getCount() {
return 5;
}
#Override
public CharSequence getPageTitle(int position) {
switch (position){
case 0 :
return "Desire";
case 1 :
return "Buyed";
case 2 :
return "Started";
case 3 :
return "Finished";
case 4 :
return "AllTrophies";
}
return null;
}
}
}
There is the layout of the MainActivity:

And here is the layout code of the TabLayout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="wrap_content">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
app:tabGravity="fill"
app:tabMode="scrollable"
android:background="#color/colorPrimary"
app:tabIndicatorColor="#android:color/holo_orange_dark"
app:tabSelectedTextColor="#android:color/holo_orange_dark"
app:tabTextColor="#android:color/white"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
</android.support.design.widget.TabLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>

You replace the content of your FrameLayout with an Fragment. this leads to your strange result.
Add a Layout to your Framelayout instead and use it as your FragmentContainer:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:backgroundTint="#color/colorPrimary"
app:borderWidth="0dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/content_frame"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="30dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:id="#+id/txt_Mainactvt_currentConsole"
android:layout_gravity="center_horizontal|top"
android:layout_marginTop="50dp"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab_AddGame"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="17dp"
android:layout_marginRight="17dp"
android:src="#drawable/ic_mode_edit_white_24dp"
android:layout_gravity="bottom|right"
android:background="#color/colorPrimary" />
</FrameLayout>

Try to place your FrameLayout with this button to the end of layout

Why does my scrollview leave "shadows" behind? - java

For anyone here looking for an answer, the way I fixed the issue was changing the fragment additions to fragment replacements. For some reason it was adding the fragments twice, hence the "shadows". Replacing instead of adding ensured there was only one loaded and fixed the issue.
