I'm not too sure why this is happening... i'm guess that alignBaseline affects measuring differently and causes a cyclic dependency (Romain?)
Try changing the relationships so you'll define A and B Below C instead, since C has a constant location anyhow. Also if your View hierarchy isnt too complex and wouldn't need to be refreshed too often, you can let yourself use more ViewGroups (use a linearlayout to divide the top and the bottom views)... Although that increases the amount of views you have and makes the rendering tree bigger, it will be easier for you to read the XML and understand the behavior and also prevent this weird behavior.
