设置排序过滤器时没有结果

Question

我是Android和解析的新手。我已经将一些图片上传到我的解析后端，并希望在我的应用中显示它们。

我知道图像在那里并且可以访问，因为当我禁用我的过滤器时，我得到了我想要的结果。我已经查看了我的代码，所有内容都检查出来，但没有结果。我有什么可以忽略的？

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_feed);

final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linearLayout);
Intent intent = getIntent();
final String activeUserName = intent.getStringExtra("username");

setTitle(activeUserName + "'s Feed");    

ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("Image");
//query.whereEqualTo("username", activeUserName);
//query.orderByDescending("createdAt");

query.findInBackground(new FindCallback<ParseObject>() {
                         @Override
                         public void done(List<ParseObject> objects, ParseException e) {
                           if (e == null) {
                             if (objects.size() > 0) {
                               for (ParseObject object : objects) {
                                 ParseFile file = (ParseFile) object.get("image");

                             file.getDataInBackground(new GetDataCallback() {
                               @Override
                               public void done(byte[] data, ParseException e) {
                                 if (e == null && data != null) {
                                   Bitmap bitmap = BitmapFactory.decodeByteArray(data, 0, data.length);

                                   ImageView imageView = new ImageView(getApplicationContext());
                                   imageView.setLayoutParams(new ViewGroup.LayoutParams(
                                     ViewGroup.LayoutParams.MATCH_PARENT,
                                     ViewGroup.LayoutParams.WRAP_CONTENT
                                   ));
                                   imageView.setImageBitmap(bitmap);

                                   linearLayout.addView(imageView);
                                 }
                               }
                             });
                           }
                         } else {
                           Toast.makeText(UserFeedActivity.this, activeUserName + " " + getString(R.string.feed_no_images), Toast.LENGTH_SHORT).show();
                         }
                       }
                     }
                   }

）; }
