Android通知时间格式如何更新？

所以,有些代码有点像这样：

class MyCLeverThing extends service (say) {

    // Your stuff here

    private static intentFilter timeChangeIntentFilter;
    static {
        timeChangeIntentFilter = new IntentFilter();
        timeChangeIntentFilter.addAction(Intent.ACTION_TIMEZONE_CHANGED);
        timeChangeIntentFilter.addAction(Intent.ACTION_TIME_CHANGED);
    }

    // Somewhere in onCreate or equivalent to set up the receiver
    registerReceiver(timeChangedReceiver,timeChangeIntentFilter);

    // The actual receiver
    private final BroadcastReceiver timeChangedReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context,Intent intent) {
        final String action = intent.getAction();

        if (action.equals(Intent.ACTION_TIME_CHANGED) ||
            action.equals(Intent.ACTION_TIMEZONE_CHANGED))
        {
            updateWidgets();  // Your code to rebuild the remoteViews or whatever
        }
    }
};
