我试图通过停止线程来停止，但没有成功.有任何想法吗?预先感谢您的帮助

I tried to stop by stopping the thread but it was unsuccessful. Any ideas? Thank you in advance for your help

这是我的代码:

   public void startTimer() {
    startTime = System.currentTimeMillis();
    final Handler handler = new Handler();
    task =new Thread() {
        @Override
        public void run() {
            long millis = System.currentTimeMillis()-startTime;
            long secs = millis / 1000 % 60; // seconds, 0 - 59
            long mins = millis / 1000 / 60 % 60; // total seconds / 60, 0 - 59
            long hours = millis / 1000 / 60 / 60; // total seconds / 3600, 0 - limitless

            timeString = String.format("%02d:%02d:%02d", hours, mins, secs);
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    mtvtimer.setText(timeString);
                }
            });

            handler.postDelayed(task, 1000);

        }


    };
    task.start();


    }

推荐答案

鉴于 Thread.stop 已弃用，您唯一的选择是添加一些您自己的信号，例如您希望它停止时设置的布尔变量.

Given that Thread.stop is deprecated, the only option you have is to add some signalling of your own, like a boolean variable that you set when you want it to stop.

例如

boolean stop = false;
public void startTimer() {
    startTime = System.currentTimeMillis();
    final Handler handler = new Handler();
    task =new Thread() {
        @Override
        public void run() {
            if (stop) {
                return;
            }
            long millis = System.currentTimeMillis()-startTime;
            long secs = millis / 1000 % 60; // seconds, 0 - 59
            long mins = millis / 1000 / 60 % 60; // total seconds / 60, 0 - 59
            long hours = millis / 1000 / 60 / 60; // total seconds / 3600, 0 - limitless

            timeString = String.format("%02d:%02d:%02d", hours, mins, secs);
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    mtvtimer.setText(timeString);
                }
            });

           handler.postDelayed(task, 1000);
    }

然后从其他地方设置 stop = true 来停止它.(这是一个粗略的示例代码，只是为了让想法通过)

And from somewhere else, you set stop = true to stop it. (this is a rough example code, just to get the idea through)
