The easiest way of adding menu items (to specify the options menu for an activity)...

@Override

public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu_main, menu); return true;

}

@Override

public boolean onOptionsItemSelected(MenuItem item) {

getMenuInflater().inflate(R.menu.menu_main, menu);

return super.onOptionsItemSelected(item);

}

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.menu.menu_main);

}
