I'm using Android Navigation Components with nav_graph and I want to make background of all fragments transparent. I tried to use the code from following resource: click For activity it's working fine, but in fragment background is always white.
public class SettingsFragment extends Fragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_settings, container, false);
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
view.setBackground(new ColorDrawable(Color.TRANSPARENT));
}
}
The easiest way to solve this is to set the transparency of the Fragment in the XML.
You can define a transparent color in colors.xml
like this: <color name="transparent">#00000000</color>
and then reference it in your fragment.xml like this: android:backgroundTint="@color/transparent"
Additionally its advisable, to set View-Altering commands into the onCreate()
.
Also you can define an android:alpha="0"
attribute in the .xml
to test if that will set the background color to transparent. But I guess this will only change the opacity of the whole fragment including child elements.
