Android通知时间格式如何更新？

我正在使用自定义RemoteView for AndroidNotification,我想模仿系统行为.

Android如何更新其通知时间格式 – 设置后是否会更改？我怎么能模仿这种行为？

最佳答案

鉴于您自己提供了答案,我不确定您是否还在寻找答案.但是,如果您希望实现原始目标,则可能需要

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
        }
    }
};
