I have a fragment and an onTouch event to switch to another fragment
public boolean onTouch(View v, MotionEvent event) {
int x = (int)event.getRawX();
int y = (int)event.getRawY();
if (event.getAction() == MotionEvent.ACTION_DOWN) {
FragmentManager fm = getActivity().getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.fragment_stars, fragment);
ft.addToBackStack(null);
ft.commit();
}
return false;
}
But the icon in the sidebar doesn't change, it stays in the parent fragment I tried to set checked in onCreateOptionsMenu but no work Also I add setHasOptionsMenu(true); in onCreateView
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater){
inflater.inflate(R.menu.sidebar, menu);
MenuItem item = menu.findItem(R.id.sistemFragment);
item.setChecked(true);
super.onCreateOptionsMenu(menu, inflater);
}
sistemFragment is fragment I point to, but it doesn't change the cheched, it stays in the parent fragment
Finally I have solved it with NavigationUI, I'm not sure if it's the right way, but it works
