Fragment over another fragment issue

Question

Set clickable property on the second fragment's view to true. The view will catch the event so that it will not be passed to the main fragment. So if the second fragment's view is a layout, this would be the code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:clickable="true" />

Solution is pretty simple. In our second fragment (that overlaps our main fragment) we just need to catch onTouch event:

@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstance){
    View root = somehowCreateView();

    /*here is an implementation*/

    root.setOnTouchListener(new View.OnTouchListener() {
        public boolean onTouch(View v, MotionEvent event) {
            return true;
        }
    });
    return root;
}

Just add clickable="true" and focusable="true" to parent layout

 <android.support.constraint.ConstraintLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:clickable="true"
      android:focusable="true">

      <!--Your views-->

 </android.support.constraint.ConstraintLayout>

If you are using AndroidX, try this

 <androidx.constraintlayout.widget.ConstraintLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:clickable="true"
      android:focusable="true">

          <!--Your views-->

 </androidx.constraintlayout.widget.ConstraintLayout>

You should hide the first fragment when you are showing the second Fragment if two fragments is placed in same container view.

If you want to know more questions about how to solve problems about Fragment, you can see my library: https://github.com/JustKiddingBaby/FragmentRigger

FirstFragment firstfragment;
SecondFragment secondFragment;
FragmentManager fm;
FragmentTransaction ft=fm.beginTransaction();
ft.hide(firstfragment);
ft.show(secondFragment);
ft.commit();

You need to add android:focusable="true" with android:clickable="true"

Clickable means that it can be clicked by a pointer device or be tapped by a touch device.

Focusable means that it can gain the focus from an input device like a keyboard. Input devices like keyboards cannot decide which view to send its input events to based on the inputs itself, so they send them to the view that has focus.

Metod 1:

You can add to all fragments layout

android:clickable="true"
android:focusable="true"
android:background="@color/windowBackground"

Metod 2: (Programmatically)

Extend all fragment from FragmentBase etc. Then add this code to FragmentBase

@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    getView().setBackgroundColor(getResources().getColor(R.color.windowBackground));
    getView().setClickable(true);
    getView().setFocusable(true);
}
