重叠具有适当高度的布局

Question

我正在尝试显示3个选项时，图标设置点击。我想覆盖它，它实际上工作（好好的）。

我的问题是第二个布局高度是手动设置的，我想改变它的高度与正常框（它的一个布局回收器视图项）相同。

有没有人可以帮助我如何设置第二个项目的高度与前一个项目的高度相同？我在OnBindViewWholder中尝试过，但没有成功

在照片下，我将添加来自适配器的xml文件和代码

Answer 1

我有两个问题

1. 主约束布局的高度
2. 不正确测量高度。

在我修复了这些问题之后，我设置了当前对象高度的最小值和最大值

   holder.local_normal_box.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED)
    var height: Int = holder.local_normal_box.getMeasuredHeight()

    holder.local_settings_box.maxHeight = height
    holder.local_settings_box.minHeight=height
