Hi Nguyen i created the same scene but getting fragment_2 on top after back from activityB
This my code
`public class FirstActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_first);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment1()).commit();
}
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment1 extends Fragment {
public PlaceholderFragment1() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_first, container, false);
Button button = (Button) rootView.findViewById(R.id.btn);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
getActivity().getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment2()).commit();
}
});
return rootView;
}
}
public static class PlaceholderFragment2 extends Fragment {
public PlaceholderFragment2() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_second, container, false);
Button button = (Button) rootView.findViewById(R.id.btn);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(getActivity(), Secondctivity.class);

}
});
return rootView;
