我有两个TextView的一个小部件显示时间和日期。

I have a widget with two TextView showing the time and date.

我只是希望这批code的发生每秒：

I simply want this batch of code to happen every second:

views.setOnClickPendingIntent(R.id.rl, pendingIntent);
java.util.Date noteTS = Calendar.getInstance().getTime();
String time = "kk:mm";
String date = "dd MMMMM yyyy";

views.setTextViewText(R.id.tvTime, DateFormat.format(time, noteTS));
views.setTextViewText(R.id.tvDate, DateFormat.format(date, noteTS));

所以，我需要一个简单的方法，在小部件定期更新的TextView所以时间的变化比标准的30分钟以上。谢谢

So I need a simple way to update TextView periodically in the widget so the time changes more than the standard 30 mins. Thanks

您可以创建处理程序和的Runnable ，然后让处理程序在指定的时间重新启动的Runnable 。你的程序可能是这样的：

you may create Handler and Runnable, and then let the Handler to restart your Runnable at the specified interval. your program might look like this:

private Handler mHandler = new Handler();

@Override
public void onResume() {
    super.onResume();
    mHandler.removeCallbacks(mUpdateClockTask);
    mHandler.postDelayed(mUpdateCLockTask, 100);
}

@Override
public void onPause() {
    super.onPause();
    mHandler.removeCallbacks(mUpdateClockTask);
}

private Runnable mUpdateClockTask = new Runnable() {
    public void run() {
        updateClock();
        mHandler.postDelayed(mUpdateClockTask, 1000);
    }
};

和里面的 updateClock（）你做你的所有UI更新。我想这一切都发生在活动与适当的的onPause（）/ onResume（）通话中。

and inside updateClock() you do all your UI updates. I suppose all this happens inside the Activity with the appropriate onPause()/onResume() calls.
