停止當前線程問題

Question

我的問題是我運行一個方法進入線程和30秒後我將顯示alertdialog並單擊alertdialog的ok按鈕我將停止當前線程，但問題是線程不停止，以下是我的代碼和對不起對於英語不好交際

public class CountDownTimerActivity extends Activity implements Runnable { 

    Thread t; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     t = new Thread(this); 
     t.start(); 

    } 

    @Override 
    public void run() { 
     // TODO Auto-generated method stub 
     myTimer.start(); 
     mDeclaration(); 
     myTimer.cancel(); 
    } 

    private CountDownTimer myTimer = new CountDownTimer(30000, 1000) { 
     // This will give you 30 sec timer with each tick at 1 second 

     public void onTick(long millisUntilFinished) { 

     } 

     public void onFinish() { 
      t.interrupt(); 
      //t.stop(); 
      AlertDialog.Builder alert = new AlertDialog.Builder(
        CountDownTimerActivity.this); 
      alert.setMessage("Loading..."); 
      alert.setPositiveButton("OK", 
        new DialogInterface.OnClickListener() { 

         @Override 
         public void onClick(DialogInterface dialog, int which) { 
          // TODO Auto-generated method stub 

         } 
        }); 
      alert.show(); 
     } 
    }; 

    public void mDeclaration() { 
     for (int i = 0; i < 100000; i++) { 
      System.out.println("Printing OK" + i); 
     } 
    } 
} 

Answer 1

看到這個question ......相反，你可以把運行方法的標誌..並檢查是否運行或不能在線程中運行代碼。

Answer 2

試試這個： -

public class CountDownTimerActivity extends Activity implements Runnable { 

Thread t; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    t = new Thread(this); 
    t.start(); 

} 

@Override 
public void run() { 
    // TODO Auto-generated method stub 
    myTimer.start(); 
    mDeclaration(); 
    myTimer.cancel(); 
} 

private CountDownTimer myTimer = new CountDownTimer(30000, 1000) { 
    // This will give you 30 sec timer with each tick at 1 second 

    public void onTick(long millisUntilFinished) { 

    } 

    public void onFinish() { 

     AlertDialog.Builder alert = new AlertDialog.Builder(
       CountDownTimerActivity.this); 
     alert.setMessage("Loading..."); 
     alert.setPositiveButton("OK", 
       new DialogInterface.OnClickListener() { 

        @Override 
        public void onClick(DialogInterface dialog, int which) { 
        // t.interrupt(); 
     t.stop(); 
        } 
       }); 
     alert.show(); 
    } 
}; 

public void mDeclaration() { 
    for (int i = 0; i < 100000; i++) { 
     System.out.println("Printing OK" + i); 
    } 
} 

}
