Android Water Ripple Effect implementation

1. Under the drawable file, create a new seletor, as the background of the button, here I use the shape of two rounded corners

<?XML version= "1.0" encoding= "Utf-8"?><selectorxmlns:android= "Http://schemas.android.com/apk/res/android"><Itemandroid:drawable= "@drawable/shape_btn_cycle_normal"/>    <Itemandroid:state_pressed= "true"android:drawable= "@drawable/shape_btn_cycle_press"/></selector>

Shape_btn_cycle_normal

<?XML version= "1.0" encoding= "Utf-8"?><Shapexmlns:android= "Http://schemas.android.com/apk/res/android"Android:shape= "Rectangle">    <CornersAndroid:bottomleftradius= "20DP"Android:bottomrightradius= "20DP"Android:topleftradius= "20DP"Android:toprightradius= "20DP"/>    <SolidAndroid:color= "@color/colorwhite"/></Shape>

Shape_btn_cycle_press

<?XML version= "1.0" encoding= "Utf-8"?><Shapexmlns:android= "Http://schemas.android.com/apk/res/android"Android:shape= "Rectangle">    <CornersAndroid:bottomleftradius= "20DP"Android:bottomrightradius= "20DP"Android:topleftradius= "20DP"Android:toprightradius= "20DP"/>    <SolidAndroid:color= "@color/colorgray"/></Shape>

2. Under the DRAWABLE-V21, the new ripple with selector name, as above, my selector is SELECTOR_BTN_CYCLE_BG, here drawable-v21 under the new Selector_btn_cycle_ Bg.xml

 <?  xml version= "1.0" encoding= "Utf-8"  ?>  <  ripple  xmlns:android  = "Http://schemas.android.com/apk/res/android"   Android:color  = "@color/colorgray"  >  //color of the selected water ripple  <  item  android:drawable  = "@drawable/shape_btn_cycle_normal"  />  //unselected background State  </ ripple  >
