Remarks
All or part of a child is dirty and needs to be redrawn.
The location array is an array of two int values which respectively define the left and the top position of the dirty child.
This method must return the parent of this ViewParent if the specified rectangle must be invalidated in the parent. If the specified rectangle does not require invalidation in the parent or if the parent does not exist, this method must return null.
When this method returns a non-null value, the location array must have been updated with the left and top coordinates of this ViewParent.
This member is deprecated. Use #onDescendantInvalidated(View, View) instead.
