如何創建一個布爾方法從處理器

Question

返回值我創建了一個類來檢查設備互聯網接入，我的類別代碼被

public class CheckInternet { 


private static Handler h = new Handler() { 
     @Override 
     public void handleMessage(Message msg) { 
      if (msg.what != 1) { // code if not connected 
       status = false; 
       System.out.println("Status False"); 
      } else { // code if connected 
       status = true; 
       System.out.println("Status True"); 
      } 
     } 
    }; 

private static void isNetworkAvailable(final Handler handler, final int timeout) { 
     new Thread() { 
      private boolean responded = false; 
      @Override 
      public void run() { 
       new Thread() { 
        @Override 
        public void run() { 
         HttpGet requestForTest = new HttpGet("http://m.google.com"); 
         try { 
          new DefaultHttpClient().execute(requestForTest); // can last... 
          responded = true; 
         } catch (Exception e) {} 
        } 

       }.start(); 

       try { 
        int waited = 0; 
        while(!responded && (waited < timeout)) { 
         sleep(100); 
         if(!responded) { 
          waited += 100; 
         } 
        } 
       } 
       catch(InterruptedException e) {} // do nothing 
       finally { 
        if (!responded) { handler.sendEmptyMessage(0); 


        } 
        else { handler.sendEmptyMessage(1); 
        } 
       } 

      } 

     }.start(); 



    } 
} 

我想創建返回我一個公共靜態布爾方法狀態，我想出了一些代碼

private static Boolean status = true ;  
public static Boolean isConnected() { 
      Runnable runnable = new Runnable() { 
       public void run() { 
        // TODO Auto-generated method stub 
        isNetworkAvailable(h,2000); 
       } 
      }; 
      runnable.run(); 
      return status; 
     } 

但問題是，它總是返回我老的狀態值，因爲當線程運行時，該方法給我的老狀態值。 我想獲得更新的狀態值。

您更好地使用

isReachable（超時）
