here menu xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:mayapp="http://schemas.android.com/apk/res-auto">     <item         android:id="@+id/edit_button"         mayapp:icon="@android:drawable/ic_menu_edit"         android:title="edit"         mayapp:showasaction="always" /> </menu> 

thanks in advance

in fragment, in oncreateview() method, have add:

sethasoptionsmenu(true); 

otherwise oncreateoptionsmenu() never called.
