Change Actionbar gravity to right

I've created a new project with a Navigation Drawer and it works fine but my problem is I want to change the top ActionBar gravity from left to right.

I want to change that icon on the left's gravity to the right Here is an example image from google play store:

Action bar Items are aligned to the right. To be able to align to the left, you will need a custom view. But you can use actionViewStyle for buttons to make them styled as menu items.

If you were asking how to make the navigation drawer slide from right to left, then in your drawer layout, make the listview from android:layout_gravity="start" to android:layout_gravity="right"

Hope this helps.
