这是我的计划

公共类喜扩展活动实现OnClickListener，Runnable接口 { /**当第一次创建活动时调用。 */

TextView txt; 
Button but1; 
String str;

    super.onCreate(savedInstanceState);

    but1.setOnClickListener(this); 

}

     } 
    } catch (Exception ex) { 
     ex.printStackTrace(); 
    } 
    return in; 
}

    }

    { 

        //str = DownloadText("http://www.yahoo.com"); 
      //txt.setText(str); 
     Thread t=new Thread(new hi()); 
     t.start(); 

     } 

    @Override 
    public void run() 
    { 

     str = DownloadText("http://www.yahoo.com"); 
      txt.setText(str); 

    }

}
