问题描述
据我所知， MATCH_PARENT 表示视图想成为大如其父（负填充），而 WRAP_CONTENT 意味着视图想要刚好足够大包围其内容（加上填充）
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)
我的问题是，当一个 MATCH_PARENT 视图（view A）是把 WRAP_CONTENT 视图中（会发生什么鉴于B）？怎么是两个视图A和B在这种情况下计算参数？
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?
推荐答案
它填补允许其母公司，上层次仰视。所有的空间可能
It fills all the space possible allowed for its parents, looking up on hierarchy.
如果该WRAP_CONTENT视图的父有大小限制，将采取大小。
如果没有层次父有大小（所有人都WRAP_CONTENT直到根视图），它会占用整个屏幕。
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.
