android - How I can retrieve current fragment in NavHostFragment?

Question

I tried to find a method in the new Navigation components but I didn't find anything about that.

I have the current destination with :

mainHostFragment.findNavController().currentDestination

But I can't get any reference to the displayed fragment.

question from:https://stackoverflow.com/questions/50689206/how-i-can-retrieve-current-fragment-in-navhostfragment

Answer 1

Reference to the displayed fragment (AndroidX):

public Fragment getForegroundFragment(){
    Fragment navHostFragment = getSupportFragmentManager().findFragmentById(R.id.nav_host_fragment);
    return navHostFragment == null ? null : navHostFragment.getChildFragmentManager().getFragments().get(0);
}

Here nav_host_fragment is an ID of the fragment tag in your activity_main.xml with android:name="androidx.navigation.fragment.NavHostFragment"
