"http://schemas.android.com/apk/res/" Android ">
<item android:state_pressed=" true ">
<shape android:shape=" Rectangle ">
< Solid android:color= "#73c4f3"/>
<stroke android:width= "2DP" android:color= "#ffffff"/>
< Corners android:radius= "20DP"/>
<padding android:bottom= "5DP" android:left= "10DP" android:right= "10DP" android:top= "5DP"/>
<gradient android:angle= "270" android:endcolor= "#8accf2" android:startcolor= "# 8accf2 "android:type=" Sweep "/>
</shape>
<shape>
<solid android:color=" #3fb3f6 " >

<corners android:radius= "20DP"/>
<padding android:bottom= "5DP" android:left= "10DP" android:right= "10DP" android:top= "5DP"/>

Second, style style:

<item name= "Android:layout_width" >match_parent</item>
< Item Name= "Android:layout_height" >wrap_content</item>
<item name= "Android:textsize" >15sp</ item>
<item name= "Android:textcolor" > #ffffff </item>
<item name= "Android:background" > @drawable/buttonclickstyle</item>

<?xml version= "1.0" encoding= "Utf-8"?> <relativelayout xmlns:android=
"http://schemas.android.com/apk" /res/android "
xmlns:tools=" Http://schemas.android.com/tools "
android:layout_width=" Match_parent
