Just a simple demo of how Android ViewGroups work in certain situations.
If you set the visibility flag on any ViewGroup in Android, that visibility flag will not be propagated to that ViewGroup's children.
This demo app does the XML setup for GONE, INVISIBLE, and VISIBLE, as well as Java tests for the same set of flags.
