我有像 facebook 这样的帖子，如果他启用或禁用，我如何检查我喜欢的按钮
我的json

}
我可以在 Adapter_messages 上查看吗？
我的适配器

}
holder.img_facebook.setOnClickListener(new View.OnClickListener() {

@Override

});
}
@Override
public int getItemCount() {

}
class AdapterHolder extends RecyclerView.ViewHolder
{
CircleImageView profile_image_message;
TextView txt_message,txt_type,txt_likes,txt_authorname;

ImageView img_copy,img_facebook,img_whatsapp;
public AdapterHolder(View itemView) {
super(itemView);

txt_authorname = (TextView)itemView.findViewById(R.id.txt_authorname);
txt_message = (TextView)itemView.findViewById(R.id.txt_message);

likeButton = (LikeButton)itemView.findViewById(R.id.likebutton);
favoritebutton = (LikeButton)itemView.findViewById(R.id.favoritebutton);

img_facebook = (ImageView)itemView.findViewById(R.id.img_facebook);
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
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.LinearLayoutManager;

import com.android.volley.toolbox.Volley;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import java.util.ArrayList;
import es.dmoral.toasty.Toasty;
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);
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);
}
}
4 天前，我正在尝试以自己的方式检查它或任何想法，但没有任何结果我希望得到想法或好的解决方案，提前致谢
我不知道这是否最好，但我就是这样做的。
String idsLikedThis;
for(int i = 0; i < like.size(); i++)
idsLikedThis = like.get(i)+",";
idsLikedThis = idsLikedThis.substrings(0, idsLikedThis.length() - 1);
String id,userid,authorname,message,likes,idsLikedThis,type;
public Item_Messages(String id, String userid, String authorname, String message, String likes, String idsLikedThis, String type) {
this.id = id;
this.userid = userid;
this.authorname = authorname;
this.message = message;
this.likes = likes;
this.idsLikedThis = idsLikedThis
this.type = type;
}
ArrayList<String> idsLikedThis = Arrays.AsList(item_messages.idsLikedThis.split(","));
if(idsLikedThis.contains("users id"))
button.enable
