Answer 1

Set ListView gravity right or end instead of start

android:layout_gravity="right" 

Also update the DrawerToggle to :

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
        R.drawable.ic_drawer, R.string.drawer_open,
        R.string.drawer_close) {

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item != null && item.getItemId() == android.R.id.home) {
            if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {
                // Notice the Gravity.Right 
                mDrawerLayout.closeDrawer(Gravity.RIGHT);
            } else {
                mDrawerLayout.openDrawer(Gravity.RIGHT);
            }
        }
        return false;
    }
};

From Docs :

The drawer view (the ListView) must specify its horizontal gravity with the android:layout_gravity attribute. To support right-to-left (RTL) languages, specify the value with "start" instead of "left" (so the drawer appears on the right when the layout is RTL).

Answer 2

Its as simple as vjdhama said. Adding onto the above you will have to change your ListView to below.

<ListView
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="end" //change this, you can also use **right**
    android:choiceMode="singleChoice"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp"
    android:background="#ffff"/>

Also, remember to change the occurence of Gravity.START/ Gravity.LEFT to Gravity.END/ Gravity.Right if you are using it for closing or opening the drawer. Have fun. :)

Answer 3

If you want to add this action from the button before is open, I found a solution:

toolbar = (Toolbar) findViewById(R.id.tool_bar);
Drawer = (DrawerLayout) findViewById(R.id.DrawerLayout);
mDrawerToggle = new   ActionBarDrawerToggle(this,Drawer,toolbar,R.string.openDrawer,R.string.closeDrawer){

@Override
public void onDrawerOpened(View drawerView) {
    super.onDrawerOpened(drawerView);
}
@Override
public void onDrawerClosed(View drawerView) {
    super.onDrawerClosed(drawerView);
}
}; // Drawer Toggle Object Made
Drawer.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();               
toolbar.setNavigationOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
    if (Drawer.isDrawerOpen(Gravity.RIGHT)) {
        Drawer.closeDrawer(Gravity.RIGHT);
    } else {
        Drawer.openDrawer(Gravity.RIGHT);
    }
}
});
