1. FramesLayout & Image View Pages 20-21

2. FrameLayout is a ViewGroup that divides the screen into blocks of area each of which is supposed to holds a single child View. You may place multiple child Views inside a single block, then the latter ones will overlay the preceding ones. The android:layout_gravity attribute of the child View will dictate which block it will go into. Let's build a page using FrameLayout as the layout model that contains an ImageView overlaid with a TextView.
