问题
I run into a problem while I was settings up the Preferences for my App.
I would like to have a Button in the ActionBar (e.g. Save) but my ActionBar is not showing anything. I put this Line in the onCreate Method:
this.setHasOptionsMenu(true);
And implemented the
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
public boolean onOptionsItemSelected(MenuItem item)
methods as well. However, it does not show anything.

Be sure your button item in your action menu layout something like:
<item
android:id="@+id/action_save"
android:orderInCategory="1"
your_icon:showAsAction="always"
android:icon="@drawable/icon_save"
/>
