如何通过单击菜单项从一个片段到另一个片段 go

Question

I want to move from the fragment I am in by the add (+) item to the add fragment. How do I switch between fragments in the menu? enter image description here

@Override
public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.student_list_menu,menu);
}

@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
    if (item.getItemId() == R.id.addStudentFragment){
        Log.d("TAG","ADD...");
        return true;
    }else {
        return super.onOptionsItemSelected(item);
    }
}

Menu view

Answer 1

just use navigation component and navigate

 @Override
public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.student_list_menu,menu);
}

@Override
public boolean onOptionsItemSelected(@NonNull MenuItem item) {
    if (item.getItemId() == R.id.addStudentFragment){
        Log.d("TAG","ADD...");
findNavController(HERE YOUR FRAGMENT ID YOU WANT TO NAVIGATE)
        return true;
    }else {
        return super.onOptionsItemSelected(item);
    }
}
