我想将图像添加到gridView。我从Parse.com拉我的内容。我不会将它们放在资源文件夹中，所以我找不到有用的教程。这是我迄今为止的代码;使用parse.com添加图像库

progressDialog = ProgressDialog.show(manager.this, "", "Loading images...", true); 
    ParseQuery<ParseObject> query = ParseQuery.getQuery("fightGallery"); 
    query.findInBackground(new FindCallback<ParseObject>() { 
     @Override 
     public void done(List<ParseObject> parseObjects, com.parse.ParseException e) { 
      if (e == null) { 
       int i = 0; 
       final int size = parseObjects.size(); 
       while (i < size) { 
        ParseFile fileObject = parseObjects.get(i).getParseFile("image"); 
        fileObject.getDataInBackground(new GetDataCallback() { 
         @Override 
         public void done(byte[] bytes, ParseException e) { 
          if (e == null) { 
           Log.d("Data", "We have data successfully"); 
           Bitmap bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length); 
           ImageView img = (ImageView) findViewById(R.id.imageView); 
           img.setImageBitmap(bmp); 
           Log.d("IMAGES", "IMAGES LOADED SUCCESSFULLY"); 
           progressDialog.dismiss(); 
          } else { 
           Log.d("ERROR: ", "" + e.getMessage()); 
           progressDialog.dismiss(); 
          } 
         } 
        }); 
        i++; 
       } 
      } else { 
       Log.d("ERROR:", "" + e.getMessage()); 
       progressDialog.dismiss(); 
      } 
     } 
    });
