为什么在应用视图绑定时 Constraintlayout 项目不可见？

Question

这是 recyclerview 项布局文件：

    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

</androidx.constraintlayout.widget.ConstraintLayout>

这个布局看起来像这样：

当我以正常方式实现 recyclerview adpater 时，此布局看起来不错。但是，当在 recyclerview 适配器中使用 View Binding 时， 只有那些 layout_width 未设置为 0dp 的元素可见。 UI 个具有 0dp 的元素不可见 。如果我使用 RelativeLayout 而不是 ConstarintLayout. But, I want to use ConstraintLayout`，这个问题就会得到解决。那么，可能是什么问题？我该如何解决这个问题？

Answer 1

我解决了这个问题。我从这个

替换了onCreateViewHolder()中的代码

ActivitySummaryListTxnItemV2Binding.inflate(LayoutInflater.from(container.getContext()));

对此：

ActivitySummaryListTxnItemV2Binding.inflate(LayoutInflater.from(container.getContext()), container, false);

Why ConstraintlLayout items are not visible when applying View Binding?
