问题描述

这是Android的少的问题,更Parse.com问题,但我需要你的帮助:

It's less android question and more Parse.com question, but I need your help:

我在我的应用程序表中的图像文件在Parse.com

I have an image file in a table in my application at Parse.com

该文件是好的,我可以手动下载并观看。

The file is ok, I can manually download it and watch it.

但是,试图开始使用的parseObject我alreay从服务器获取它的时候,我得到空

But when trying to get it using parseObject that I alreay get from server, I'm getting "null"

code:

  byte[] imageFile = parseObject.getBytes(Statics.COL_IMAGE_FILE);

我在做什么错了?

What am I doing wrong?

P.S。 :我可以看到的parseObjectestimatedData字段中的图像文件的数据/链接,但不能让他

p.s. : I can see the image file data/link in the parseObject "estimatedData" field, but can't get him.

推荐答案

如果 Statics.COL_IMAGE_FILE 是的 文件 列,你应该做到以下几点得到的byte []:

If Statics.COL_IMAGE_FILE is a File column, you should do the following to get byte[]:

ParseFile imageFile = (ParseFile)parseObject.get(Statics.COL_IMAGE_FILE);
imageFile.getDataInBackground(new GetDataCallback() {
  public void done(byte[] data, ParseException e) {
    if (e == null) {
      // data has the bytes for the image
    } else {
      // something went wrong
    }
  }
});
