How to change option menu icon in the action bar?

Question

How to change the index icon of option menu?

I mean icon (3).

Here is my code:

@Override public boolean onCreateOptionsMenu(Menu menu) {     MenuInflater inflater = getMenuInflater();     inflater.inflate(R.menu.options, menu);      return true; } 

And here is the XML file:

<item android:id="@+id/Bugreport"     android:title="@string/option_bugreport" />  <item android:id="@+id/Info"     android:title="@string/option_info" />  <item android:id="@+id/About"     android:title="@string/option_about" />

The following lines should be updated in app -> main -> res -> values -> Styles.xml

 <!-- Application theme. --> <style name="AppTheme" parent="AppBaseTheme">     <!-- All customizations that are NOT specific to a particular API-level can go here. -->     <item name="android:actionOverflowButtonStyle">@style/MyActionButtonOverflow</item> </style>  <!-- Style to replace actionbar overflow icon. set item 'android:actionOverflowButtonStyle' in AppTheme --> <style name="MyActionButtonOverflow" parent="android:style/Widget.Holo.Light.ActionButton.Overflow">     <item name="android:src">@drawable/ic_launcher</item>     <item name="android:background">?android:attr/actionBarItemBackground</item>     <item name="android:contentDescription">"Lala"</item> </style> 

This is how it can be done. If you want to change the overflow icon in action bar
