      "Likes": [

      ]

  ]
}

我可以在Adapter_messages查看吗？

            txt_authorname = (TextView)itemView.findViewById(R.id.txt_authorname);
            txt_message = (TextView)itemView.findViewById(R.id.txt_message);
            txt_type = (TextView)itemView.findViewById(R.id.txt_type);
            txt_likes = (TextView)itemView.findViewById(R.id.txt_likes);
            likeButton = (LikeButton)itemView.findViewById(R.id.likebutton);
            favoritebutton = (LikeButton)itemView.findViewById(R.id.favoritebutton);
            img_copy = (ImageView)itemView.findViewById(R.id.img_copy);

            img_whatsapp = (ImageView)itemView.findViewById(R.id.img_whatsapp);
        }
    }


}

这是我的自定义数组列表

import java.util.ArrayList;

public class Item_Messages {


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


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

和类ShowMessages

    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);
        JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, Information.URL_Messages + type, null, new Response.Listener<JSONObject>() {
            @Override
            public void onResponse(JSONObject response) {
                try {


                    for (int x = 0; x < response.getJSONArray("posts").getJSONObject(x).length() ; x++) {
                        item_messages.add(new Item_Messages(response.getJSONArray("posts").getJSONObject(x).getString("id"),response.getJSONArray("posts").getJSONObject(x).getString("userid"),response.getJSONArray("posts").getJSONObject(x).getString("authorname"),response.getJSONArray("posts").getJSONObject(x).getString("message"),String.valueOf(response.getJSONArray("posts").getJSONObject(x).getJSONArray("Likes").length()),response.getJSONArray("posts").getJSONObject(x).getString("type")));
                    }
                } 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(jsonObjectRequest);



    }
}
