android - 通过单击通知打开图库文件夹

Question

我使用此代码发送通知。

  public static void sendNotificationPhoto(Context context, Class<?> activityTarget)
        {
            Log.i( TAG , "Send Photo Notification");

            NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
            Notification notifyDetails = new Notification(R.drawable.ic_plusone_standard_off_client, "New Alert!", System.currentTimeMillis());
            Intent intent = new Intent(context, activityTarget);

            int id = NOTIFICATION_ID_PHOTO;
            String contentText = "Slave Picture Is Now Available!";


            PendingIntent contentIntent = PendingIntent.getActivity(context.getApplicationContext(), id, intent, PendingIntent.FLAG_ONE_SHOT);
            notifyDetails.setLatestEventInfo(context.getApplicationContext(), context.getString(R.string.app_name), contentText, contentIntent);
            mNotificationManager.notify(id, notifyDetails);
        }

但现在我不需要打开另一个 Activity ，而是打开特定画廊的文件夹。是否可以通知？

你可以这样做

Intent intent = new Intent(Intent.ACTION_VIEW,ImageUri);
ImageUri = "content://media/external/images/media/1210"`

在pendingIntent中调用这个intent

PendingIntent contentIntent = 
     PendingIntent.getActivity(context.getApplicationContext(),
                               id,
                               intent,
                               PendingIntent.FLAG_ONE_SHOT
     );

上面的Imageuri是为了表示。之后这对我有用多次尝试其他选项。如果你提供这个 Intent 不起作用file.getpath 或 file.getabsolutepath

我试过使用 Uri.fromFile 并且成功了:

intent = new Intent(Intent.ACTION_VIEW,Uri.fromFile(fileName));
