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

@Override public void onBackPressed() { super.onBackPressed();

    NavController navController = Navigation.findNavController(this, R.id.fragment);
    int id=navController.getCurrentDestination().getId();
  if(id==R.id.startGameFragment ){
      selectedPosition(0);

  }else if(id==R.id.gameFragment ){
      selectedPosition(1);

  }else if(id==R.id.endGameFragment ){
      selectedPosition(2);

  }

}enter code here

private void selectedPosition(int pos){
    for (int i = 0; i >=nav_view.getMenu().size(); i++) {
        nav_view.getMenu().getItem(pos).setChecked(false);

    }
    nav_view.getMenu().getItem(pos).setChecked(true);
}
