如何在选项卡Activity中的片段中使用onCreateOptionsMenu？(Sherlock ActionBar)

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.your_menu_file, menu);
}

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/action_example"
        android:icon="@drawable/ic_example"
        android:title="@string/action_example"
        app:showAsAction="ifRoom"/>

</menu>

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.action_example:
            // 处理点击事件
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

public class MainActivity extends SherlockFragmentActivity {
    // ...
}
