How to stop a running thread when Activity on destroy at Android?

Question

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:

Answer 1

try this way:

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();

}

and

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