It's probably due the fact that View.GONE will prevent the View from being drawn to the screen, while another View android:layout_align[POSITION] component may be defined to that View, so their position can't be calculated.

View.INVISIBLE will work cause it just make it invisible, but the View is still there and other View can calculate their position if the align is set to it
