dies versuchen.

android.view.ActionMode mMode = toolbar.startActionMode(new Callback() { 

      @Override 
      public boolean onPrepareActionMode(
        ActionMode mode, Menu menu) { 
        return false; 
      } 

      @Override 
      public void onDestroyActionMode(
        ActionMode mode) { 

      } 

      @Override 
      public boolean onCreateActionMode(
        ActionMode mode, Menu menu) { 
        return false; 
      } 

      @Override 
      public boolean onActionItemClicked(
        ActionMode mode, MenuItem item) { 
        return false; 
      } 
}); 

wenn Sie wollen Fininsh Action-Modus

if (mMode != null) { 
     mMode.finish(); 
} 

Und vergessen Sie nicht folgende in Ihrem Haupt-Thema unter hinzufügen styles.xml

<item name="android:windowActionModeOverlay">true</item> 

Sie sind gut zu gehen.
