線程中使用處理程序

我想在我的線程中使用處理程序，但會產生錯誤。這是我的代碼，函數的一部分，我有問題，其中控制是一個布爾和一個線程。線程中使用處理程序

private void mainbucle() { 

     bucle = new Thread(new Runnable() { 
      @Override 
      public void run() { 

       while (control == true) { 


        Handler handler2 = new Handler(); 
        handler2.postDelayed(new Runnable() { 
         public void run() { 

               //MY ACTIONS// 

         } 
        }, 1000); 

       } 
      } 
     }, "bucle telo"); 
     bucle.start(); 
    }

而且這個logcat的：

在哪裏，如何使用循環指令？

感謝

UPDATE

隨着答案我是誰，我解決了控制bucle的問題，但現在沒有按鈕是responds..this其監聽器的代碼：

private View.OnClickListener btnClick = new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      switch (v.getId()) { 
      case R.id.btnStart: { 
       control = true; 
       enableButtons(true); 
       mainbucle(); 
       break; 
      } 
      case R.id.btnStop: { 
       control = false; 
       enableButtons(false); 
       bucle = null; 
       break; 
      } 
      } 
     } 

    };

請澄清你的問題。 Btw將'control == true'拋出一個編譯錯誤，因爲控件沒有被定義。 –

什麼是錯誤？ –

發佈'LogCat'。 –

你必須在新線程外附加處理程序，然後在線程內使用它：

private void newThread() { 

    Handler h = new Handler(); 
    Thread t = new Thread(new Runnable() { 
     @Override 
     public void run() { 
      //... 
      h.postDelayed(new Runnable() { 
        public void run() { 
         //... 
        } 
       }, 1000); 

     } 
    }); 
    t.start(); 
}

當您發佈的處理程序，您的代碼將在哪個線程運行的處理程序連接到它
（你必須重視主線程中處理程序，以避免錯誤）

編輯： this may help you

運行良好，但現在的問題是，onclicklistener聽按鈕將控制爲false並停止bucle不起作用。所以永遠不要停止 – user3243651

你可以發佈你的真實代碼嗎？ –

真的你想要做什麼？ –
