Android uses shape to define colors, background colors, border colors for different controls

The right and bottom border color of the set button is red and the border size is 3DP:

Create a new Buttonstyle.xml file in drawable with the following contents:

<?xml version= "1.0" encoding= "UTF-8"?> <layer-list  xmlns:android= "Http://schemas.android.com/apk/res /android >   <!--box color values--><item>         <shape>               <solid android:color= "#ff0000"/>         </shape>   </item>   <!--body background color value-  <item android:bottom= "3DP" android:right= " 3DP ">        <shape>              <solid android:color=" #ffffff "/>                          <padding android:bottom=" 10DP "                   android:left= "10DP"                  android:right= "10DP"                  android:top= "10DP"/ >       </shape>       </item>  

The button inside the layout file is then set as follows:

<button     android:id= "@+id/button1"     android:layout_width= "Wrap_content"      Android:layout_height= "Wrap_content"     android:text= "Button1"     android:background= "@drawable/buttonstyle"/>
