Android上的Activity销毁时如何停止正在运行的线程? [英] How to stop a running thread when Activity on destroy at Android?

问题描述

我在Android活动中使用了一些线程对象.但是，当Activity销毁时，这些线程不会自行停止.我的线程停止代码如下:

I used some thread objects in my Android activity. But these threads do not stop itself when Activity on destroy. My code for thread-stopping as following:

@Override
public void onDestroy() {
    super.onDestroy();
    thread.interrupt();
}

以上代码不仅适用于线程对象停止，而且还会引发InterruptedException.在没有异常的情况下停止正在运行的线程的正确方法是什么?

Above code is not only working for thread object stopping but also throws an InterruptedException. What's the correct way to stop a running thread without exceptions?

线程对象抛出InterruptedException时不是错误吗?

is it not an error when thread object throws InterruptedException?

推荐答案

尝试这种方式:

volatile boolean stop = false;

public void run() {
    while ( !stop ) {
     log.v("Thread", "Thread running..." );
      try {
      Thread.sleep( 1000 );
      } catch ( InterruptedException e ) {
      log.v("Thread","Thread interrupted..." );
      }
    }
}

@Override
public void onDestroy() {
    stop = true;
    super.onDestroy();

}

和

@Override
public void onDestroy() {
    thread.interrupt();
    super.onDestroy();   
}
