如何在解析中加载图像

Question

我在解析中有一个类photo，并且在我的项目中有一个。

所以我从photo想加载图像并将其与trade_id设置为我imageviews。 告诉我我该怎么做，请！

做这样

ParseQuery<ParseObject> queryPhoto = ParseQuery.getQuery("photo"); 
    queryPhoto.whereEqualTo("trade_id",trade_id); 
    queryPhoto.findInBackground(new FindCallback<ParseObject>() { 
     @Override 
     public void done(List<ParseObject> listPhoto, ParseException e) { 
      // TODO Auto-generated method stub 
      if(e == null){ 
       for (ParseObject photo : listPhoto){ 
        ParseFile parseFile = (ParseFile)photo.get("imageFile"); 
        final String imageName =photo.getString("imageName"); 
        if (parseFile != null) { 
          parseFile.getDataInBackground(new GetDataCallback() { 

           @Override 
           public void done(byte[] data, ParseException e) { 
            // TODO Auto-generated method stub 
            if (data != null && e == null) { 
              Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0,data.length); 
              if(imageName.equals("image1")) 
                imageVIew1.setImageBitmap(bitmap); 
               else if(imageName.equals("image2")) 
                imageVIew2.setImageBitmap(bitmap); 
               else if(imageName.equals("image3")) 
                imageVIew3.setImageBitmap(bitmap); 
               else if(imageName.equals("image4")) 
                imageVIew4.setImageBitmap(bitmap);          } 
           } 
          }); 
         } 
       } 
      } 
     } 
    });

@kishore jethava is also right but you can also get url from parse then load that url into imageview with the help of any library like Glide or Picassio or even you can download the image manually from the provided url. 

ParseQuery<ParseObject> queryPhoto = ParseQuery.getQuery("photo"); 
     queryPhoto.whereEqualTo("trade_id",trade_id); 
     queryPhoto.findInBackground(new FindCallback<ParseObject>() { 
      @Override 
      public void done(List<ParseObject> listPhoto, ParseException e) { 
       // TODO Auto-generated method stub 
       if(e == null){ 
        for (ParseObject photo : listPhoto){ 
         ParseFile parseFile = photo.getParseFile("imageFile"); 
         if(parseFile!=null) 
         { 
          final String imageULr=parseFile.getUrl(); 
         Glide.with(context).load(imageULr).into(imageView); 
         } 
         } 
        } 
       } 
      } 
     });
