如何设置Android同步状态图标的动画？

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.

Answer 1

我找到了答案......

http://libs-for-android.googlecode.com/svn-history/r46/trunk/src/com/google/android/accounts/AbstractSyncService.java

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);
}

要获得动画同步图标,您可以使用android.R.drawable.ic_popup_sync图标.例如,使用更新的通知构建器,您可以使用以下内容:

Notification notification = new NotificationCompat.Builder(mContext)
        .setContentTitle("my-title")
        .setContentText("Loading...")
        .setSmallIcon(android.R.drawable.ic_popup_sync)
        .setWhen(System.currentTimeMillis())
        .setOngoing(true)
.build();
