推荐答案

所以，我是有上Build.VERSION_ codeS.JELLY_BEAN_MR2有一个问题，当我们想创建一个事实在于该问题的 MeasureSpec ：

So the problem I was having lies on the fact that Build.VERSION_CODES.JELLY_BEAN_MR2 has a problem when we want to create a MeasureSpec:

MeasureSpec.makeMeasureSpec(ViewGroup.LayoutParams..., MeasureSpec.EXACTLY);

使用 MeasureSpec.EXACTLY 时，我如执行 .measure（widthMeasureSpec，heightMeasureSpec）; 返回值完全陌生的，所以这个问题就可以，如果我们使用解决了 MeasureSpec.AT_MOST 而不是 MeasureSpec.EXACTLY 。

With MeasureSpec.EXACTLY when I perform for example a .measure(widthMeasureSpec, heightMeasureSpec); it returns values completely strange, so this problem can be solved if we use MeasureSpec.AT_MOST instead of MeasureSpec.EXACTLY.

希望它可以帮助别人的未来;）
PS：我不知道，如果Android的奇巧（4.4，API 19）有这个问题了。

编辑：它

Hope it helps someone in the future ;)
ps: I don't know if Android Kitkat (4.4, API 19) has this problem too.

it does.

int widthMeasureSpec;
int heightMeasureSpec;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
    widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(ViewGroup.LayoutParams.MATCH_PARENT, View.MeasureSpec.AT_MOST);
    heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(ViewGroup.LayoutParams.WRAP_CONTENT, View.MeasureSpec.AT_MOST);
} else {
    widthMeasureSpec = View.MeasureSpec.makeMeasureSpec(ViewGroup.LayoutParams.MATCH_PARENT, View.MeasureSpec.EXACTLY);
    heightMeasureSpec = View.MeasureSpec.makeMeasureSpec(ViewGroup.LayoutParams.WRAP_CONTENT, View.MeasureSpec.EXACTLY);
}
