所以我在jsonapi.org处理格式，我只是在我的字段中保持为空。不知道我做错了什么。
这是我试图解析的JSON的片段（它根本没有提交包含）
{
"jsonapi": {
"version": "1.0"
},
"meta": {
"page": "1",
"pages": "59",
"records": "588",

},
"data": [
{
"id": "2619621",
"type": "TalkThread",
"attributes": {
"name": "Cracked paint",

},
"links": {

},
{

"type": "TalkPost",
"attributes": {

}
}
]
},

"attributes": {
"name": "Property/DIY"
},
"links": {
"self": "property"
}
}
}
},
"site": {
"name": "site"
}
}
我已经建立了一个不按我的意图工作的模型类。
SearchTalkThread.java
import com.gustavofao.jsonapi.Annotations.Type;
import com.gustavofao.jsonapi.Models.Resource;
/**
* Created by bilalhaider on 15/05/2017.
*/
@Type("TalkThread")
public class SearchTalkThread extends Resource {
public String name;
public String created;
public String thread_view;
public String first_nick;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getCreated() {
return created;
}
public void setCreated(String created) {
this.created = created;
}
public String getThread_view() {
return thread_view;
}
public void setThread_view(String thread_view) {
this.thread_view = thread_view;
}
public String getFirst_nick() {
return first_nick;
}
public void setFirst_nick(String first_nick) {
this.first_nick = first_nick;
}
}
现在我正在使用github用户的faogustavo的JSONApi库（link），但它还没有计划好。我会得到ID，类型和链接但是关于它。
我的要求是：

任何人都可以帮助我找到我需要去的地方或我需要做什么吗？它一直在向我强调几天，我只是无法弄清楚我做错了什么！
编辑添加了用于获取JSON的其他类。我遇到的问题是在获取数据后解析数据。

而不是使用api.fromJson尝试下面的代码来解析Json。
public static final String JSON_ARRAY = "data";
public static final String KEY_ID = "id";
public static final String KEY_NAME = "name";
public static final String KEY_EMAIL = "link";
protected void parseJSON(){
JSONObject jsonObject=null;
try {
jsonObject = new JSONObject(json);
users = jsonObject.getJSONArray(JSON_ARRAY);
ids = new String[users.length()];
names = new String[users.length()];
emails = new String[users.length()];
for(int i=0;i<users.length();i++){
JSONObject jo = users.getJSONObject(i);
ids[i] = jo.getString(KEY_ID);
names[i] = jo.getString(KEY_NAME);
emails[i] = jo.getString(KEY_EMAIL);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
只是检查你是否得到了值。

您尝试获取的数据是动态的（来自Web服务）还是静态的（项目中包含的json文件）？
我已经浏览了您为JSONAPI提供的链接，在该代码中有MainActivity，其中有用于获取数据的代码，是否可以添加相同的代码。
