Calling a method in one fragment from another

Question

I\'ve been trying for a while already (as well, searching in here) for something to help me to refresh listView in my MainFragment, when a button is pressed in other fragmen

Answer 1

            // Calling Parent Fragment method from Child Fragment.
        // Child Fragment
        AppCompatActivity activity = (AppCompatActivity) view.getContext();
        FragmentManager fragmentManager = activity.getSupportFragmentManager();
        NavigateFragment navigateFragment = (NavigateFragment) fragmentManager.findFragmentById(R.id.fragment_place_dashboard);
        navigateFragment.sayHelloWorld();


        // -- Some method in Parent Fragment(NavigateFragment).
        public void sayHelloWorld(){
            Log.d(TAG, "Hello World.");
        }
