Android Fragment handle back button press [duplicate]

Answer 1

Add this code in your Activity

@Override

public void onBackPressed() {
    if (getFragmentManager().getBackStackEntryCount() == 0) {
        super.onBackPressed();
    } else {
        getFragmentManager().popBackStack();
    }
}

And add this line in your Fragment before commit()

ft.addToBackStack("Any name");
