Suggested Answer: B 🗳️
need to create context menu. For this need to override this method:
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); menu.setHeaderTitle("My Context Menu"); menu.add(0, NEW_MENU_ITEM, 0, "new"); menu.add(0, SAVE_MENU_ITEM, 1, "save");
}
And last one need to handle menu clicks:
@Override
public boolean onContextItemSelected(MenuItem item) {
switch (item.getItemId()) {
case NEW_MENU_ITEM:
doSomething();
break;
case SAVE_MENU_ITEM:
doSomething();
break;
}
return super.onContextItemSelected(item);
}
