android - 如何为 Android 同步状态图标制作动画？

Question

我只想启动和停止状态栏中的同步图标。我认为这将是一个使用 NotificationManager 的简单调用，但我无法在 Web 或 SO 上找到文档或示例问答。

我找到了我的答案......

这显示了如何设置和取消 stat_notify_sync 图标。

private void showNotification(String authority) {
    Object service = getSystemService(NOTIFICATION_SERVICE);
    NotificationManager notificationManager = (NotificationManager) service;
    int icon = android.R.drawable.stat_notify_sync;
    String tickerText = null;
    long when = 0;
    Notification notification = new Notification(icon, tickerText, when);
    Context context = this;
    CharSequence contentTitle = "mobi"; //createNotificationTitle();
    CharSequence contentText = "bob"; //createNotificationText();
    PendingIntent contentIntent = createNotificationIntent();
    notification.when = System.currentTimeMillis();
    notification.flags |= Notification.FLAG_ONGOING_EVENT;
    notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
    notificationManager.notify(mNotificationId, notification);
}

private void cancelNotification() {
    Object service = getSystemService(NOTIFICATION_SERVICE);
    NotificationManager nm = (NotificationManager) service;
    nm.cancel(mNotificationId);
}
