问题描述
我正在尝试扩充一个 XML，作为 RecyclerView 的一个项目，该 XML 是带有两个 TextView 的约束布局 两个 TextViews 的背景与我创建的相同，它位于 drawable 文件夹中，并且是一个矩形形状，以便在 textviews 周围创建框架线。
但是当我运行该应用程序时，出现此错误：
Binary XML file line #9: Error inflating class TextView
通过阅读类似的问题，我发现这可能是由于 textview 的某些属性而发生的，在我的情况下，当我从 textview 中删除这些背景时，膨胀有效，一切正常。
谁能解释为什么会这样？ XML、可绘制形状和错误如下：
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

android:layout_width="match_parent"

>
<TextView

</shape>
