I am making a game that requires multiple views within an Activity, and i decided to use Viewflipper to do.
The thing is. I need to have 3 views in in the viewflipper, and the LAST view will transfer back to the first one.
My problem is that the buttons are acting weird, and they are either not going to the next, or skipping the third view. I tried to put vf.setDisplayedChild(R.Id.gamescreen1); at the last view but then the whole thing breaks down.
Thanks for all answers in advance, i have been stuck with this problem for DAYS! and yes, i know that i am a noob :(

try this
flipper.setDisplayedChild(1);
.
.to
.
flipper.setDisplayedChild(3);
if(flipper.getCurrentView() == 3)
{
flipper.setDisplayedChild(1);
}
setDisplayChild takes an integer parameter that is the zero based index of the child to display NOT the id of the child to display. A bit confusing I know.

This part of the code is to add 3 EditText lines while the button secbutt is clicked. While all three EditText lines are on the screen, the button should disappear.
Now I do not understand why after entering onClick method and starting plusTextField method, it just adds EditText lines infinitely. I want it to execute once and to return to the beginning of summonButton method. What should I do?

You miss logic of setting the button invisible when counter riches 0 :
public void onClick(View view) {
plusTextField();
if(numberOfLinesLeft == 0) {
view.setVisibility(View.GONE);
}
}
Here is the result, there is no button after adding 3 Edit Texts:
I'm new to Android and recently created a dashboard for my app. I followed a tutorial but it only covered the front end. I created a layout called content_main.xml with three Cardviews. Each of these Cardviews contains the code
android:clickable="true"
Beginning the back end of things, I created a java receiver class called DashboardActivity (as seen below). I want to make my Cardviews clickable so that when one is clicked, I am taken to another screen within my app. The other screens in my app I am trying to get to are fragments. Each of these screens has its own java class in my "Fragments" folder. One of them, of which I try calling on in the code that follows is called SettingsViewFragment().
So far, I have tried the following. It does nothing.
public class DashboardActivity extends AppCompatActivity {
CardView cd1, cd2, cd3;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_main);
cd1 = (CardView) findViewById(R.id.dash_settings);
cd2 = (CardView) findViewById(R.id.dash_profile);
cd3 = (CardView) findViewById(R.id.dash_activity);
cd1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Fragment fragment1 = new SettingsViewFragment();
}
});
}
}
UPDATE: FULL CODE
public class DashboardActivity extends AppCompatActivity {
CardView cd1, cd2, cd3;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_main);
cd1 = findViewById(R.id.dash_settings);
cd2 = findViewById(R.id.dash_profile);
cd3 = findViewById(R.id.dash_activity);
cd1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.i("Testing 123 123 123");
}
});
}
}
And my XML: (it continues for 3 cards this way)

Replace
Fragment fragment1 = new SettingsViewFragment();
With this
Fragment fragment1 = new SettingsViewFragment();
FragmentTransaction fragmentTransaction=getFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.Main_Layout,fragment1);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
Change Fragment fragment1 = new SettingsViewFragment (); by Toast.makeText (mActivity, "onCLick", Toast.LENGTH_LONG) .show ();
//if show toast The problem is not the onClick, the problem is when loading the fragment
Fragments should be instantiated with the newInstance() static method.
cd1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Fragment settingsFragment = SettingsFragment.newInstance();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.contentView, settingsFragment);
fragmentTransaction.commit();
}
});
In the SettingsFragment
public static SettingsFragment newInstance() {
return new SettingsFragment();
}

This will transact the fragment into the FrameLayout that is positioned below the CardViews. Now this is probably not ideal, you would most likely want to launch a new activity that will host the fragment but this should work. Unless this is already in some Activity that hosts the fragment. But the key code is in the onClick.
I'm trying to create a simple Bottom Sheet layout, One button shows and other collapse, but its not working. I was following this tutorial but still nothing.So I'm trying to pass the state inside of buttons and then pass into the callback method to hide or expand, and the bottom sheet can't be scrolled down!
This is the layout.

Activity :

bottomSheet = findViewById( R.id.bottom_sheet );
button1 = (Button)findViewById(R.id.button_1);

mBottomSheetBehavior = BottomSheetBehavior.from(bottomSheet);
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
mBottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
#Override
public void onStateChanged(View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_COLLAPSED) {
mBottomSheetBehavior.setPeekHeight(0);
}
if(newState == BottomSheetBehavior.STATE_EXPANDED){
mBottomSheetBehavior.setPeekHeight(500);
}
}
#Override

});
button1.setOnClickListener(new View.OnClickListener() {

});
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
});
I ran into the same issue when trying that tutorial myself.
You have to set the BottomSheetBehavior to be hideable. Moreover, the COLLAPSED state may not be what you are looking for. To make the BottomSheet disappear completely, you have to set the state to HIDDEN. Like this:
mBottomSheetBehavior.setHideable(true);
mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_HIDDEN);
Put TextView into LinearLayout
SOLVED THE CODE BELOW WORKS
If I have a layout similar to the one below:
Those five temp EditTexts represent some info the user can enter (like the price of an item, the order number, etc.) If the user wants to add another item they would click on the Add button and I want another 5 textviews to appear on the screen right above the two buttons but right below the previous set of the 5 EditTexts. Can someone give me a starting point on how I would do this.
My layout of the fragment goes like this:
I have a top level linear layout (Vertical Orientation).
Then a scrollview.
Inside the scrollview I have another linear layout.
In that linear layout I have those five EditText objects and the two buttons
The view above is a fragment (defined in the file below) which I pass to my FragmentAdapter in my MainActivity file:
public class Device extends Fragment {
ScrollView scrollView;
LinearLayout ll;
#Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.device_view, container, false);
scrollView = (ScrollView) rootView.findViewById(R.id.device_scroll_view);
ll = (LinearLayout) rootView.findViewById(R.id.layout_in_scrollview);
Button addButton = (Button) rootView.findViewById(R.id.add_another_device_button);
addButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
View temp = inflater.inflate(R.layout.edit_text_view_objects, container, false);
ll.addView(temp);
}
});
return rootView;
}
}
Here is my layout file for this fragment:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<EditText

android:textSize="15dp"
android:gravity="center"
android:layout_gravity="center"

</LinearLayout>
in your XML take
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/device_scroll_view">
<LinearLayout
android:id="#+id/layoutDynamic"a
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center_horizontal">
</LinearLayout>
</ScrollView>
and create one more XML for your Item and design accordingly (It will add dynamically when you click on ADD)
dynamic_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/device_fragment_linear_layout"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="DeviceFragment"
android:orientation="vertical">
<TextView
android:id="#+id/etDynamic"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="15dp"
android:gravity="center"
android:layout_gravity="center"
android:hint="Color"
android:layout_marginTop="10dp"/>
</LinearLayout>
so come to java Code
// take the reference of LinearLayout
linearLayout = (LinearLayout) romptView.findViewById(R.id.layoutDynamic);
// Take the reference of Add button
Button addButton = (Button) rootView.findViewById(R.id.add_another_device_button);
addButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
final View addView = layoutInflater1.inflate(R.layout.dynamic_row, null);
final TextView textView1 = (TextView) addView.findViewById(R.id.etDynamic);
textView1.setText(otheret.getText().toString().trim()); otheret.setText(""); linearLayout.addView(addView);
}
});
#and if you want to remove particular item
removeIcon.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
addView.getParent()).removeView(addView);
}
});
You can add these EditText through code at runtime
we can solve this, using List/Recycler view efficiently/easily
when ever you clicking on ADD add the item to list and notify the Recycler view adapter
and and removing also easy you just delete the item from list based on recycler View position.
No need to create Dynamic View here recycler view will do the job
// In Main Layout
<android.support.v7.widget.RecyclerView
android:id="#+id/recycleView_Stops"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/layoutSaveBottom"
android:layout_below="#+id/ll1"
android:layout_marginTop="#dimen/pad_10dp"
app:layout_behavior="#string/bottom_sheet_behavior" />
<TextView
android:id="#+id/tvAddOther"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:text="#string/icon_plus"
android:textColor="#color/colorPrimary"
android:textSize="40sp"
app:customFontPath="#string/roboto_regular" />
// design your layout item
---------------------
and when clicking on Add set user entered details
addOther.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
RouteElements routeElements = new RouteElements();
routeElements.setLatitude(latitude);
routeElements.setLongitude(longitude);
routeElements.setStopName(otheret.getText().toString().trim());
routeElementsArrayList.add(routeElements);
routeStopsAdapter.notifyDataSetChanged();
});
And in Your Adapter for removing the item
public void remove(int position) {
if (position < routeElementsArrayList.size()) {
routeElementsArrayList.remove(position);
notifyDataSetChanged();
}
}
i need to declare my Chronometer on onCreate() of my fragment because if I declare on onCreateView(), every time the ChronometerFragment is called the Chronometer is reseted.
My actual code:
ChronometerFragment.class
public class CronometroFragment extends Fragment {
Button btStart, btPause, btReset;
boolean click;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

My problem is that user cannot change fragment because this reset the Chronometer.
Please, can someone help me?
Thanks.
This question is badly formulated.. But in your onCreate, put setretaininstance(true). This should work. :-)
