I have tried every tutorial on the first google page about android fragments, but I can\'t get anything to work.
So I have one navigation bar activity, MainAct
Try this one. it is my newbie code easier to understand :)
FragmentTransaction transaction;
switch (id){
case R.id.button_fragment_one:
transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.frame_layout, new FragmentOne());
transaction.addToBackStack(null);
transaction.commit();
break;
case R.id.button_fragment_two:
transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.frame_layout, new FragmentTwo());
transaction.commit();
break;
default:
break;
}
