Question

我想在主活动的下面代码中调用pauseThread方法阻止currentcore整数计数。一些示例代码将不胜感激。如果那不可能，那么他们是否可以停止点击按钮？也许暂停线程？

public class ScoreThread extends Thread {

private boolean counter;
private int currentscore;
Handler scorehandler = new Handler();
private TextView playerscore;

 ScoreThread(TextView v, Boolean b) {
    playerscore = v;
    counter = b;
}

public void pauseThread() throws InterruptedException {
    counter = false;
}

public void resumeThread() throws InterruptedException {
    counter = true;
}


public void run() {
    currentscore = 0;
    new Thread(new Runnable() {
        @Override
        public void run() {
            while(counter == true) {
                currentscore = currentscore + 1;

                scorehandler.post(new Runnable() {
                    @Override
                    public void run() {
                        playerscore.setText("" + currentscore);
                    }
                });
                try{ Thread.sleep(50);} catch (InterruptedException e) {e.printStackTrace();}
            }
        }
    }).start();
}
}

您应该使用一个线程来执行计算。调用另一个线程是没用的。我简要介绍了如何实现目标

class Score extends Thread {

    private boolean counter;
    private int currentscore = 0;

    public void stopThread() throws InterruptedException {
        counter = false;
    }

    @Override
    public void run() {
        while (counter) {
            currentscore = currentscore + 1;
            //Do rest of your work  
            try {
                Thread.sleep(50);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

}

在你的主动作中当你想开始计算时

  Score score = new Score();
        score.start();

当你想要停止线程时，例如从mainactivity调用线程的方法使用以下

try {
            //        your stop event
            score.stopThread();
        } catch (InterruptedException ex) {
            Logger.getLogger(NewClass.class.getName()).log(Level.SEVERE, null, ex);
        }
