Android: onCreateOptionsMenu() item action

Question

I have a menu created through:

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
    menu.add(\"Email\");

    return super.onCreateOptionsMenu(menu)         


        

Answer 1

Override onOptionsItemSelected(MenuItem item). So it would be like

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case 0:
            // do whatever
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

EDIT:

Since this has gotten so many points, I should note that it is very good to add ID's to the menu options. A good way to ensure they are always unique is to define them in an ids.xml resource that is put in the res/values folder.

ids.xml

Then when you override the onCreateOptionsMenu(Menu menu) method, you can use the IDs like so:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
  super.onCreateOptionsMenu(menu);

  menu.add(Menu.NONE, R.id.menu_action1, Menu.NONE, R.string.menu_action1);
  menu.add(Menu.NONE, R.id.menu_action2, Menu.NONE, R.string.menu_action1);

  return true;
}

Override onOptionsItemSelected(MenuItem item).

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.menu_action1:
            // do whatever
            return true;
        case R.id.menu_action2:
            // do whatever
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

The reason you do this is the Activity would override this with menu options, but Fragments can also add their own menu items. Using the ids.xml ensures the IDs are unique no matter which order they are placed.
