Answer 1

Your query is difficult to understand without code & stacktrace, but anyway..

Remember android.support.v4.widget.DrawerLayout can have 3 elements only (in exactly this order):

1. Your main page

2. Left Drawer

3. Right Drawer

Copy paste this example(only first two elements are there) & continue with your requirements

Your Activity:

public class MainActivity extends Activity {
RelativeLayout leftRL;
RelativeLayout rightRL;
DrawerLayout drawerLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
//        I'm removing the ActionBar.
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.temp);

    leftRL = (RelativeLayout)findViewById(R.id.whatYouWantInLeftDrawer);
    drawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout);
    }

    public  void onOpenLeftDrawer(View view)
    {
    drawerLayout.openDrawer(leftRL);
    }
}
