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 :

mainHostFrag         


        

Answer 1

From an Activity which has NavHostFragment, below code snippet can be used to retrieve the instance of the Active Fragment.

kotlin

val currentFragment = mNavHostFragment?.childFragmentManager?.primaryNavigationFragment

java

Fragment navHostFragment = getSupportFragmentManager().getPrimaryNavigationFragment();
Fragment currentFragment = navHostFragment.getChildFragmentManager().getFragments().get(0);

Answer 2

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"
