java - 中断一个线程

Question

我正在编写一个程序来使用语音命令移动玩具车我正在使用线程同时发送数据，问题是当我使用命令退出时我无法中断我的线程，请提供帮助。

if(response.equals("stop"))
   {
         motorLeft = 0;
         motorRight =0;
         (new Thread(new Runnable()
           {@Override
               public  void run()
               {
                   while (!Thread.interrupted())
                       try
                       {
                           Thread.sleep(1000);
                           runOnUiThread(new Runnable() // start actions in UI thread
                           {

                               @Override
                               public void run()
                               {
                                  // displayData(); // this action have to be in UI thread
                                 if(BT_is_connect) bl.sendData(String.valueOf( commandLeft+motorLeft+"\r"+commandRight+motorRight+"\r"));

                               }
                           });
                       }
                       catch (InterruptedException e)
                       {
                           // ooops
                       }
               }
           })).start(); // the while thread will start in BG thread
      }
      else

      {
         if(response.equals("exit"))   
            Thread.interrupted();


         }

Answer 1

例如使用变量

volatile  boolean interrupted = false;

然后使用该变量来停止

 while (!interrupted)
 {
         try
         {
            Thread.sleep(1000);
            runOnUiThread(new Runnable() // start actions in UI thread
            {
                @Override
                public void run()
                {
                    // displayData(); // this action have to be in UI thread
                    if(BT_is_connect) bl.sendData(String.valueOf(commandLeft+motorLeft+"\r"+commandRight+motorRight+"\r"));

                }
            });
        }
         catch (InterruptedException e)
        {
             // ooops
        }       
 }

因此，当您想中断线程时，只需将 interrupted 变量更改为 true

interrupted = true;
