在卡片视图中使用时，Android中带有圆角的永久性底部工作表会崩溃

问题描述

我已经在android中创建了一个持久的底部工作表，目的是显示一个包含有关位置的其他信息的ListView.我希望床单上有圆角.对于模态对话框，我有很多结果，但对于持久性却没有.有可能还是应该使用模式版本?

I have created a persistent bottom sheet in android with the intent of displaying a ListView containing additional information about locations. I want the sheet to have rounded corners. I got a ton of results for modal dialog but none for persistent. Is it possible or should I use the modal version?

根据此处答案的建议，我尝试将其包装在卡片视图中，但是当我尝试打开片段时应用程序崩溃.

As suggested in an answer here, I tried wrapping it in a card view but the app crashes when I try to open the fragment.

推荐答案

U可以为您的底部工作表背景添加形状

U can add shape for you bottom sheet background background

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">

    <solid android:color="@color/you_color"/>

    <corners
            android:bottomRightRadius="2dp"
            android:bottomLeftRadius="2dp"
            android:topLeftRadius="2dp"
            android:topRightRadius="2dp"/>
</shape>
