我如何绘制这个圆角矩形?

How do I draw this round rectangle?

enter image description here我是 Android 实习的初学者,我被赋予完成此导航抽屉的任务 app.Any 帮助将不胜感激

创建新的可绘制对象并添加以下代码:

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

    <item>
        <shape android:shape="rectangle">
            <corners android:topLeftRadius="20dp" android:bottomRightRadius="20dp"/>
            <solid android:color="@color/semi_transparent_white"/>
        </shape>
    </item>
</selector>
