Android:从解析文件加载图像视图 [英] Android : load an imageview from a Parsefile

问题描述

我正在尝试通过"objectId "找到一个 ParseObject，然后检索图像"ImageFile "，然后将其加载到 imageview，它不起作用，我正在获取 USER 字符串，你能帮我吗有了这个，当我使用另一个查询时它会起作用:query.find()

I'm trying to find a ParseObject by " objectId ", then retrieve the image " ImageFile " and then Load it to the imageview, it doesn't work and i'm getting the USER String, can you help me out with this, it works when i use another query like : query.find()

      ParseImageView mealImage = (ParseImageView) findViewById(R.id.icon);

    ParseQuery<ParseObject> query1 = ParseQuery.getQuery("Annonces");


    query1.getInBackground("ux3Af0cwEx", new GetCallback<ParseObject>() {
      public void done(ParseObject Annonces, ParseException e) {


             photoFile = (ParseFile) Annonces.get("ImageFile");
             text1.setText((CharSequence) Annonces.get("USER"));

      }
    });
    mealImage.setParseFile(photoFile);
    mealImage.loadInBackground(new GetDataCallback() {
        @Override
        public void done(byte[] data, ParseException e) {

        }
    });

    }

推荐答案

imageview中显示图片的代码:

The code for displaying image in imageview:

ParseFile image = (ParseFile) userData.getParseFile("user_image");

然后调用下面的函数.

loadImages( photoFile, mealImage);

<小时>

private void loadImages(ParseFile thumbnail, final ImageView img) {

    if (thumbnail != null) {
        thumbnail.getDataInBackground(new GetDataCallback() {
            @Override
            public void done(byte[] data, ParseException e) {
                if (e == null) {
                    Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
                    img.setImageBitmap(bmp);
                } else {
                }
            }
        });
    } else {
        img.setImageResource(R.drawable.menu);  
    }
}// load image
