根据文件显示，一切似乎都很好。
然后我使用以下代码遍历内容：
public static ArrayList<GenericPhoto> extractPhotosFromTumblrContent(TumblrPhotoDataWrapper tumbrlData) {
ArrayList<GenericPhoto> mPictures = new ArrayList<>();
Toolkit.Logd(TAG, "Working on the tumblr '" + tumbrlData.getSource() + "' which has " + tumbrlData.getTumblrRootContent().getResponse().getPosts().size() + " posts...");
for (Post post : tumbrlData.getTumblrRootContent().getResponse().getPosts()) {
Toolkit.Logd(TAG, "The post with id " + post.getId() + " has " + post.getPhotos().size() + " photos");
for (Photo photo : post.getPhotos()) {
GenericPhoto wi = new GenericPhoto();
wi.setPostId(post.getId());
wi.setTimestamp(post.getTimestamp());
//wi.setCaption(photo.getOriginalSize().getUrl());
int totalAlternativeSizesOfPhotos = photo.getAltSizes().size();
//wi.setUrlSmall(photo.getAltSizes().get(totalAlternativeSizesOfPhotos - 2).getUrl());
//wi.setUrlLarge(photo.getOriginalSize().getUrl());
//wi.setUrlSmall(photo.getAltSizes().get(2).getUrl());
Toolkit.Logd(TAG, "The post id is " + post.getId() + " and it has " + totalAlternativeSizesOfPhotos + " alternative sizes");
mPictures.add(wi);
}
}
Toolkit.Logd(TAG, "I extracted " + mPictures.size() + " from the tumblr " + tumbrlData.getSource());
return mPictures;
}
只是浏览帖子的所有图片。
问题是即使映射正确地检测到每个帖子上有多少张照片（即2,5,8），它也会检测到0个替代尺寸并且没有照片的原始尺寸。就好像杰克逊完成所有工作时，每张照片的映射都不会发生。
我尝试使用jsonschema2pojo重新创建类，清理项目，清理缓存，但似乎没有任何工作。
可能是什么问题？我还应该在哪儿看？ 可以与Proguard合作吗？可以在Android Studio中配置项目吗？
杰克逊在解析RSS新闻源以及YouTube的JSON响应方面完美无瑕地工作，这让我觉得Photos类或某些组件的配置有问题。
非常感谢任何帮助。
