httpget Gets a string fails, God help you look great.

            
Follow the example online to do is not to return a string that is needed more time android4.0 networks, can not be written in the main thread, I also opened a thread, or get less, but also add to the authority. Please God help me look great, thank you.

 public class MainActivity extends Activity {

private Button btn1 = null; 
private TextView t1 = null; 
private final String STRURL = "http://www.google.cn"; 
@ Override 
protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState); 
setContentView (R.layout.activity_main); 
btn1 = (Button) findViewById (R.id.btn1); 
t1 = (TextView) findViewById (R.id.t1); 
btn1.setText ("test"); 
btn1.setOnClickListener (new mylistener ()); 
} 

private Handler myhandler = new Handler (); 

private String GetHtmlResult (String c) 
{
String ResultString = ""; 
HttpGet httpGetRequest = new HttpGet (STRURL); 
try 
{
Log.e ("net", STRURL); 
HttpResponse httpResponse = new DefaultHttpClient () execute (httpGetRequest);. 
if (httpResponse.getStatusLine (). getStatusCode () == 200) 
{
ResultString = EntityUtils.toString (httpResponse.getEntity ()); 
} 
} 
catch (Exception ex) 
{
ResultString = ex.getMessage (); 
} 
return ResultString; 
} 



public class mylistener implements OnClickListener {

@ Override 
public void onClick (View arg0) {
MyThread m = new MyThread (); 
myhandler.post (m); 
} 

}; 

public class MyThread implements Runnable {
@ Override 
public void run () {
/ / TODO Auto-generated method stub 
t1.setText (GetHtmlResult (STRURL)); 
} 
} 
}
