Hi Oriz.

In your activity_main.xml (or whatever yours is called) then try adding these lines to your layout view:

android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"

This works for image view, so I'm guessing it will work for the different layout views.
However, be aware that the different sprites should also be positioned depending on the size of the screen. Consider using a display matrix to grab screen dimensions to start with and position graphics accordingly.

Hope this helps.

Oops!
Sorry I meant Display Metrics!!! I'm getting tired now and will soon need my bed. See below:

DisplayMetrics dm;
dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
int screenHeight=dm.heightPixels;
int screenWidth=dm.widthPixels;

Thanks.
