Android 5.0 Water Ripple Implementation

1. Define an XML with a normal rounded background;

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>

2. The water ripple effect of the XML ripple_bg.xml:

<?xml version= "1.0" encoding= "Utf-8"? ><ripple xmlns:android= "Http://schemas.android.com/apk/res/android"   Android:color= "#FF21272B" >  <item>    <shape android:shape= "Rectangle" >      <solid android:color= "#FFFFFF"/>      <corners android:radius= "4DP"/>    </shape>  </ item>  <item android:drawable= "@drawable/rounded_corners"/></ripple>

3 Use it in the layout XML

  < Button     Android:layout_width = "Match_parent"     android:layout_height= "Wrap_content"    android:background= "@drawable/ RIPPLE_BG "    android:text=" @string/hello_world "/>

If you want to be compatible with a low-system version, you need to create a new v21 (i.e. Android5.0) resource Directory.
