Android – how do I call a method from the onclicklistener.onclick method?

import java.io.InputStreamReader;
import java.io.Reader;
import java.net.URL;
import java.net.URLEncoder;

import com.google.gson.Gson;

import android.app.Activity;
import android.os.Bundle;

import android.view.View;

import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.TextView;   

public class SampleActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ImageButton button = (ImageButton) findViewById(R.id.imageButton1);        
        button.setOnClickListener(new View.OnClickListener()   {             
           public void onClick(View v)  {               
            try {
                doSomething();
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();                    
            }               
           }  
         });
       }
    public  void doSomething() throws Exception {
        EditText search2 = (EditText)findViewById(R.id.editText1);
        TextView urltext = (TextView)findViewById(R.id.textView1);
        String google = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=";
        String search = search2.toString() + "site:mysite.com";
        String charset = "UTF-8";

        URL url = new URL(google + URLEncoder.encode(search, charset));
        Reader reader = new InputStreamReader(url.openStream(), charset);
        GoogleResults results = new Gson().fromJson(reader, GoogleResults.class);
       String voidurlresult = results.getResponseData().getResults().get(0).getUrl().toString();
       urltext.setText(voidurlresult);           
    }
}

Please look at the code above... What's the problem with the code. When I click the button, I get nothing. When I click the button, I want to get the URL of the first Google result... I would be grateful if someone could help me

resolvent:

button.setOnClickListener(new View.OnClickListener()   {             
       public void onClick(View v)  {               
        try {
            SampleActivity.this.doSomething();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();                    
        }               
       }  
     });

Change the statement contained in the try statement to this. This will ensure that the correct class is referenced to call the method
