Inflating AppBarLayout with Toolbar + TabLayout

Question

I currently have a DrawerLayout in my main.xml. There\'s a Toolbar wrapped in an AppBarLayout, and then a simple LinearLayout to swap out fragments.

One of the fragment

Answer 1

I had a similar issue where I wanted a TabLayout just inside of one fragment.

Without changing any other code you can solve this by using onAttach and onDetach inside your fragment with the TabLayout.

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);

    // todo add some further checks, e.g. instanceof, actionbar != null

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        ((AppCompatActivity) activity).getSupportActionBar().setElevation(0);
    }
}

@Override
public void onDetach() {
    super.onDetach();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        ((AppCompatActivity) getActivity()).getSupportActionBar()
                .setElevation(getResources().getDimension(R.dimen.toolbar_elevation));
    }
}

Be sure to set the same elevation on your TabLayout and everything works fine! ;D
