Just a click on the "test button", that part of the ui on the right will disappear < br />
Button testing resources as follows:
Button Normal:
Button is pressed:

This can press down, not by the results. Put under drawable directory.
Button btn;
btn.setBackground (getResources () getDrawable (R.drawable.xxx).);

This is the test code

 
package com.example.testradiobutton; 


import android.os.Bundle; 
import android.app.Activity; 
import android.widget.Button; 
import android.widget.RelativeLayout; 

public class MainActivity extends Activity 
{

private RelativeLayout baseLayout; 

protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState); 

baseLayout = new RelativeLayout (this); 

Button btn2 = new Button (this); 
btn2.setText ("test button"); 
btn2.setBackground (this.getResources () getDrawable (R.drawable.test_btn).); 

baseLayout.addView (btn2); 

this.setContentView (baseLayout); 
} 
} 

The real test is not successful, I'll try other machines
