如何获取和显示Wordpress特色媒体和作者图像？

JMA*_*R B 9 java android android-layout wordpress-rest-api

我正在创建一个显示WordPress帖子的Android应用程序.目前,该应用程序正在显示标题和副标题(3行文字)但是,它没有显示特色图像.我也很想得到作者的图像(如果可能的话),但我更担心特色图像.我试图谷歌,但我可能会问错误的问题.我也试图获得图像路径,但它根本不起作用.根据JSON特色图片包含一个id,这个id可以用来获取路径.但是,没有运气.

编辑: 我试图在RecycleViewAdapter.class中添加此代码,但仍然没有运气

Glide.with(mContext).load(response.body().getMediaDetails().getSizes().getThumbnail().getSourceUrl())
                    .into(imageView);

编辑 - 所以,有人给我发了一些细节.但我仍然没有得到它.我最后一次尝试创建Android应用程序是在2014-2015.以下是详细信息:

是的,您可以从WordPress网站上获取所有内容.WordPress商店博客帖子图像在另一张桌子上.所以按照这一步

1)使用REST APi获取博客帖子.它将是一个JSON数组.

2)检查每个json对象,每个都有这个JSON对象 - Links - > WpFeaturedmedia ---> object(0) - > Href

3)此Href是博客文章的图像索引.

4)将此href传递给适配器..

5)内部适配器类再次使用另一个改进调用此href url

6)此改造的响应将包含博客文章的所有图像(多种尺寸).response.body().getMediaDetails().getSizes().getThumbnail().getSourceUrl()

7)将它传递给glide方法(仅限adpater类)Glide.with(mContext).load(response.body().getMediaDetails().getSizes().getThumbnail().getSourceUrl()).into(imageView);

最后,适配器中的响应POJO不是您在活动中使用的响应POJO.为图片网址创建另一个POJO.

好吧，经过一些研究后，我发现您只需_embed在网址末尾进行连接，您就可以获得特色图像以及带有图像的作者简介。

这是演示网址

从那里您可以获取_embed对象内的作者数据
