Answer 1

It's quite simple actually. Easier than with ActionBar. I'm writing the answer with almost simplest of layouts

make your xml something like this:

Then make your activity something like this:

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.activity_main);

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

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

    public  void onRight(View view)
    {
    drawerLayout.openDrawer(rightRL);
    }
}

That's it. Hope it helps.
