Moving the Drawer Toggle From Left To Right in Action Bar

Question

In my Activity I have a drawer list that pops from the right but I'm not able to move the drawer toggle from the left to the right side. Please if somebody can help me solve this issue.I just want to move the toggle to the right of the action bar.

package com.parse.starter;



import com.parse.ParseUser;

public class UserDrawer extends AppCompatActivity {

//Declaring Variables
private ListView DrawerList;
private ArrayAdapter<String> Adapter;
private ActionBarDrawerToggle DrawerToggle;
private DrawerLayout DrawerLayout;
private String ActivityTitle;



final ParseUser currentUser = ParseUser.getCurrentUser();
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_user_drawer);

    DrawerList = (ListView) findViewById(R.id.navList);
    DrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActivityTitle = getTitle().toString();
    addDrawerItems();
    setupDrawer();

    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);

    Button Sample = (Button) findViewById(R.id.button);

}

//Method To Add Items To The List View
private void addDrawerItems() {
    String[] DArray = {"Job List", "Notifications", "Messages", "Log Out"};
    Adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, DArray);
    DrawerList.setAdapter(Adapter);
    DrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            if (position == 0) {
                Intent i0 = new Intent(UserDrawer.this, Set_Info.class);
                startActivity(i0);
            } else if (position == 1) {
                //Intent i1 = new Intent(Drawer1.this, AddPatient.class);
                //startActivity(i1);
            } else if (position == 2) {
                //Intent i2 = new Intent(Drawer1.this, Notifications.class);
                //startActivity(i2);
