我怎样才能创建这样的背景形状
How can I create a background shape like this
我有 cardview，目前看起来像这样。这些 cardviews 在 list view 里面。
我需要这样创建吗？
请问是否可以得到任何帮助。

感谢 Marsad 和 Zain 的回答。但是，我可以设法得到这个。但是我无法从下面指出的视图中删除形状下的 corner background。
另外这个view怎么样，可以用玻璃看吗？完整 xml 已更新。

你可以这样做
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid
android:color="#2196F3"/>
<corners
android:topLeftRadius="20dp"

</shape>
更新
这是更新后的背景可绘制对象
<?xml version="1.0" encoding="utf-8"?>
