title: Add multiple ListView lists in one single layout in Android
body: <p>I am trying to add 3 or more lists in a layout xml. I didn't expect this to be a problem, but I don't see all the lists(and they get populated) and the view does not scroll. I need an opinion to what stupid stuff I am doing here, please.</p>
