使用定时器怎么样?

private Timer timer = new Timer();
private TimerTask timerTask;
timerTask = new TimerTask() {
 @Override
 public void run() {
    //refresh your textview
 }
};
timer.schedule(timerTask, 0, 10000);

通过 timer.cancel() 取消它.在你的 run() 方法中，你可以使用 runOnUiThread();

Cancel it via timer.cancel(). In your run() method you could use runOnUiThread();

更新:

我有一个实时评分应用程序，它使用此计时器每 30 秒更新一次.它看起来像这样:

I have a livescoring app, which uses this Timer to update it every 30 sec. It looks like this:

private Timer timer;
private TimerTask timerTask;

public void onPause(){
    super.onPause();
    timer.cancel();
}

public void onResume(){
    super.onResume();
    try {
       timer = new Timer();
       timerTask = new TimerTask() {
          @Override
          public void run() {
         //Download file here and refresh
          }
       };
    timer.schedule(timerTask, 30000, 30000);
    } catch (IllegalStateException e){
       android.util.Log.i("Damn", "resume error");
    }
}
