Open Right to Left Navigation Drawer Android

open right to left Navigation Drawer in android fragment activity. it is similar to left to right as we discuss http://invokecode.blogspot.com/2015/11/custom-navigation-drawer-in-android.html
but in this we need to change line.

?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 

    xmlns:ads="http://schemas.android.com/apk/res-auto"

    android:layout_width="fill_parent"  

    android:layout_height="fill_parent">
    <android.support.v4.widget.DrawerLayout 

       android:id="@+id/drawer_layout" 

       android:layout_width="fill_parent"  

       android:layout_height="match_parent">
        <FrameLayout 

           android:id="@+id/content_frame_Home"            

           android:layout_width="match_parent"      

           android:layout_height="match_parent"/>
        <RelativeLayout  

          android:id="@+id/left_relative"   

          android:layout_width="300dp"   

          android:layout_height="wrap_content" 

           android:layout_gravity="start">
            <include layout="@layout/slider" />
        </RelativeLayout>
    </android.support.v4.widget.DrawerLayout>
</RelativeLayout> 

android:layout_gravity="start"   change to  android:layout_gravity="end"
in Coding we need to change GRAVITY LEFT To Right..
DrawerLayout drawerLayout;
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerLayout.openDrawer(Gravity.RIGHT);
