You need to create a shape drawablein the drawable folder that looks something like:
您需要drawable在 drawable 文件夹中创建一个形状，如下所示：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" >
<gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF"
android:angle="270"/>
</shape>
(For this example I have saved the drawable as circle.xml and it will have a gradient fill)
（在这个例子中，我将 drawable 保存为 circle.xml 并且它会有一个渐变填充）
Then in your layout you need to define a view and set the shape as the background:
然后在您的布局中，您需要定义一个视图并将形状设置为背景：
<View android:layout_width="50dp"
android:layout_height="50dp"
android:background="@drawable/circle"/>
The View defines the size and dimensions of the shape.
视图定义了形状的大小和尺寸。
