先在Drawable文件下創(chuàng)建兩個(gè)文件用作背景

rounded_corners.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#FFFFFF" />
    <corners android:radius="4dp" />
</shape>

ripple_bg.xml:

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="#33000000">
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#FFFFFF" />
            <corners android:radius="4dp" />
        </shape>
    </item>
    <item android:drawable="@drawable/rounded_corners" />
</ripple>

最后在對(duì)應(yīng)的view上指定

android:background="@drawable/ripple_bg"

注意：以上方法僅支持Android5.0以上版本
