I want to place that icon left to right side.
Just want to know where should I change code?
In your XML layout file, make the gravity of your drawer Gravity: right or Gravity end instead of Gravity:start
example
<ListView
android:id="@+id/drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="end" //or you can use right also.
android:choiceMode="singleChoice"
/>
