Question

我遇到了json的问题

[
  {
    "id": "1",
    "userid": "1831",
    "authorname": "WhatsApp",
    "message": "There are only two times that I want to be with you: Now and Forever.",
    "likes": "2",
    "type": "romantic",
    "yourlikes": "0"
  },
  {
    "id": "2",
    "userid": "1831",
    "authorname": "WhatsApp",
    "message": "My six word love story: “I can’t imagine life without you.”",
    "likes": "1",
    "type": "romantic",
    "yourlikes": "0"
  },
  {
    "id": "3",
    "userid": "1831",
    "authorname": "WhatsApp",
    "message": "You have no idea how much my heart races when I see you.",
    "likes": "3",
    "type": "romantic",
    "yourlikes": "1"
  },
  {
    "id": "4",
    "userid": "1831",
    "authorname": "WhatsApp",
    "message": "Since the time I’ve met you, I cry a little less, laugh a little harder and smile all the more, just because I have you, my life is a better place.",
    "likes": "0",
    "type": "romantic",
    "yourlikes": "0"
  }
]

您可以看到以下内容：

"yourlikes": "1"

当我按消息显示时，它是0

CODE

public class ShowMessages extends AppCompatActivity {

    String type;
    ArrayList<Item_Messages> item_messages = new ArrayList<>();
    RecyclerView rv_message;




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




        Intent intent = getIntent();
        type = intent.getStringExtra("type");




        RequestQueue requestQueue = Volley.newRequestQueue(this);
        JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.GET, Information.URL_Messages + Information.userid + "&type=" + type, null, new Response.Listener<JSONArray>() {
            @Override
            public void onResponse(JSONArray response) {
                try {
                    for(int x = 0 ; x < response.length() ; x++)
                    {
                        item_messages.add(new Item_Messages(response.getJSONObject(x).getString("id"),response.getJSONObject(x).getString("userid"),response.getJSONObject(x).getString("authorname"),response.getJSONObject(x).getString("message"),response.getJSONObject(x).getString("likes"),response.getJSONObject(x).getString("type"),response.getJSONObject(x).getString("yourlikes")));
                    }

                    Toast.makeText(ShowMessages.this, "" + response.getJSONObject(2).getString("yourlikes"), Toast.LENGTH_SHORT).show();
                } catch (JSONException e) {
                    e.printStackTrace();
                }

                rv_message = (RecyclerView)findViewById(R.id.rv_message);
                rv_message.setLayoutManager(new LinearLayoutManager(ShowMessages.this,LinearLayoutManager.VERTICAL,false));
                Adapter_Messages adapterview = new Adapter_Messages(ShowMessages.this, item_messages);
                rv_message.setAdapter(adapterview);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {

            }
        });
        requestQueue.add(jsonArrayRequest);



    }
}

自定义数组列表

import java.util.ArrayList;

public class Item_Messages {


    String id,userid,authorname,message,likes,type,yourlikes;


    public Item_Messages(String id, String userid, String authorname, String message, String likes, String type, String yourlikes) {
        this.id = id;
        this.userid = userid;
        this.authorname = authorname;
        this.message = message;
        this.likes = likes;
        this.type = type;
        this.yourlikes = yourlikes;
    }
}

为什么在结果中显示0而非1的任何想法？我搜索了很多，没有找到任何与此问题相关的问题问题是否在php文件中？除了以下所有数据都正确显示：

"yourlikes": "1"
or
"yourlikes": "0"

请你试着帮我，谢谢你。
