A MATCH_PARENT view inside a WRAP_CONTENT view

Question

I understand that MATCH_PARENT means that the View wants to be as big as its parent (minus padding), and WRAP_CONTENT means that the View wants to be just big enough to enclose its content (plus padding)

My question is, what happens when a MATCH_PARENT view (view A) is put inside a WRAP_CONTENT view (view B)? How are the parameters of the two views A and B calculated in this case?

Answer 1

It fills all the space possible allowed for its parents, looking up on hierarchy.

If the parent of the WRAP_CONTENT view has a size limit, it will take that size. If no hierarchical parent has size (all are wrap_content until the root view) it will take up the whole screen.
