问题描述
我正在尝试在wrap_content上设置回收器视图的高度,并使其尊重这一点,但是它将超过布局上的其他小部件. 我现在该怎么办?

推荐答案
我遇到了同样的问题,并且找到了以下解决方案: 您应该将此属性添加到您的recyclerview中,并使您的recyclerview wrap_content在constraint_layout中:
i had the same issue and i find this solution: you should add this attribute to your recyclerview and it makes your recyclerview wrap_content in the constraint_layout:
app:layout_constraintHeight_default="wrap"
让我知道此解决方案是否可以解决您的问题.
let me know if this solution fixed your problem.
回收站的高度应为0dp.
EDIT : recycler's height should be 0dp.
在较新版本的支持库中,使用以下代码:
EDIT 2 : in the newer versions of support library, use this code:
android:layout_height="wrap_content"
app:layout_constrainedHeight="true"
