Change the view's z order in the tree, so it's on top of other sibling views. This ordering change may affect layout, if the parent container uses an order-dependent layout scheme (e.g., LinearLayout). Prior to NoType:android/os/Build$VERSION_CODES;Href=../../../reference/android/os/Build.VERSION_CODES.html#KITKAT this method should be followed by calls to View.RequestLayout and View.Invalidate on the view's parent to force the parent to redraw with the new child ordering.
