android timer 强制结束,如何停止/取消android CountDownTimer

CountDownTimer.cancel()方法似乎不起作用。这是另一个没有解决方案的线程Timer does not stop in android。

我建议你使用Timer来代替。它更灵活，可随时取消。这可能是类似的东西：

public class MainActivity extends Activity {

TextView mTextField;

long elapsed;

final static long INTERVAL=1000;

final static long TIMEOUT=5000;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

mTextField=(TextView)findViewById(R.id.textview1);

TimerTask task=new TimerTask(){

@Override

public void run() {

elapsed+=INTERVAL;

if(elapsed>=TIMEOUT){

this.cancel();

displayText("finished");

return;

}

//if(some other conditions)

// this.cancel();

displayText("seconds elapsed: " + elapsed/1000);

}

};

Timer timer = new Timer();

timer.scheduleAtFixedRate(task, INTERVAL, INTERVAL);

}

private void displayText(final String text){

this.runOnUiThread(new Runnable(){

@Override

public void run() {

mTextField.setText(text);

}});

}

}
