Using onBackPressed() in Android Fragments

I didn’t find any good answer about this problem, so this is my solution.

If you want to get backPress in each fragment do the following.

create interface OnBackPressedListener

public interface OnBackPressedListener {
    void onBackPressed();

That each fragment that wants to be informed of backPress implements this interface.

In parent activity , you can override onBackPressed()

public void onBackPressed() {
    List<Fragment> fragmentList = getSupportFragmentManager().getFragments();
    if (fragmentList != null) {
        //TODO: Perform your logic to pass back press here
        for(Fragment fragment : fragmentList){
           if(fragment instanceof OnBackPressedListener){
