Android: View.setLayout() does not change the view's layout property

I've added an event to a button to change the layout property of a view. Each tap will turn the layout of this view to horizontal -> vertical -> composite then come back at horizontal, etc...

In the iOS simulator everything works like expected, the children views are relocated as the layout of the parent changes. But it does not work in the Android simulator or Android device (HTC Sensation, Android 4.1) They stay at the same place.

(The purpose of this app, was a simple test to understand the layout property.)

Could this be a bug?
