How to change the control background and shape by Android programming _android

This article illustrates how the Android programming implementation changes the control's background and shape. Share to everyone for your reference, specific as follows:

1. Changing the background

Create an XML file under Res/drawable:

<?xml version= "1.0" encoding= "UTF-8"?> <selector xmlns:android=
"http://schemas.android.com/apk/res/" Android ">
    //control is pressed against the background 
  <item android:state_pressed=" true "android:drawable=" @drawable/search_bar_ edit_pressed "/>
      //control is selected background 
  <item android:state_selected=" true "android:drawable=" @drawable/ search_bar_edit_pressed "/>
    //control background in general
  <item android:drawable=" @drawable/search_bar_edit_normal " />
</selector>

2. Change Shape

<shape>
    //gradient
  <gradient android:startcolor= "#8600ff"/>
    //stroke
  <stroke android:width= "2DP" android:color= "#000000"/>
    //Fillet
  <corners android:radius= "5DP"/>
    /margin
  <padding android:left= "10DP" android:top= "10DP"
    android:bottom= "10DP" android:right= "10DP"/>
</shape> 

To reference on a layout file:

android:background= "@drawable/"
