android - How can i add this icon to my action bar? -

how can add icon action bar? 1 of standard?

for example in item.

    <item     android:id="@+id/action_edit"     android:orderincategory="1"     android:title="ok"     android:icon="@android:drawable/ic_menu_edit"     android:visible="true"     app:showasaction="always" /> 

you can via theme xml layout adding style.xml file:

 <style name="mytheme" parent="@style/theme.appcompat.light">    <item name="icon">@drawable/actionbar_logo</item>   </style> 

or adding programmatically inside activity adding this:

getsupportactionbar().setlogo(r.drawable.ic_launcher); getsupportactionbar().setdisplayuselogoenabled(true);
