title: Android RelativeLayout doesn't stretch to fill parent's height
body: <p>Motorolla XOOM, Android 3.2. After my resource preloader(you can see a progressbar of it on the picture below) has finished his work, this window shows up, but it's height is not stretched to fill all screen. How can it be fixed?</p>
