Как создать Recycler View с помощью Retrofit + Moshi

/ 25 января 2020

Я пытаюсь добавить представление рециркулятора к ответу json.

Я могу успешно напечатать данные, полученные через ответ, в тосте, но я не уверен, как передать их по адаптеру RecyclerView , Большинство из них говорят о Конвертере Gson и ни одного на Моши

Я искал inte rnet некоторое время, но я был беспомощен.

Мне интересно, как передать данные из myactivity (OrderHistoryActivity) в RecyclerViewAdapter (OrderHistoryRecyclerAdapter).

Вот мой код

OrderHistoryActivity 

package com.tesmachino.saycure;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;

import retrofit2.Response;

public class OrderHistoryActivity extends AppCompatActivity {

    ApiService service;
    TokenManager tokenManager;

    Call<OrderHistoryResponse> call;
    private static final String TAG = "OrderHistoryActivity";

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

        tokenManager = TokenManager.getInstance(getSharedPreferences("prefs", MODE_PRIVATE));
        service = RetrofitBuilder.createServiceWithAuth(ApiService.class, tokenManager);
    }


    @Override
    protected void onResume() {

        call = service.orderHistory();

        call.enqueue(new Callback<OrderHistoryResponse>() {
            @Override
            public void onResponse(Call<OrderHistoryResponse> call, Response<OrderHistoryResponse> response) {
                Toast.makeText(OrderHistoryActivity.this, "" + response.body().getData(), Toast.LENGTH_SHORT).show();

            }

            @Override
            public void onFailure(Call<OrderHistoryResponse> call, Throwable t) {
                Log.w(TAG, "onFailure: " + t.getMessage());
                Toast.makeText(OrderHistoryActivity.this, "Please Try again after some time", Toast.LENGTH_SHORT).show();

            }

    @Override

Любая помощь по этому вопросу была бы очень признательна. Если мой вопрос неясен, пожалуйста, дайте мне знать, я был бы рад перефразировать его. Пожалуйста, объясните мне, как это работало в конце

  • В вашем OrderHistoryActivity действии возьмите RecyclerView в XML и создайте объект в OrderHistoryActivity.java.

  • создать item.xml файл Примечание. Требуется, поскольку вы используете activity_order_history (файл OrderHistoryActivity xml) для viewHolder, что неверно. 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/orderid"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>



</LinearLayout>
  • Сейчас Измените OrderHistoryRecyclerAdapter. java как: 

package com.tesmachino.saycure;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;

import com.tesmachino.saycure.entities.OrderHistory.OrderHistoryResponse;

import java.util.ArrayList;
import java.util.List;

import retrofit2.Call;


public class OrderHistoryRecyclerAdapter extends RecyclerView.Adapter<OrderHistoryRecyclerAdapter.ViewHolder> {

 private List<OrderHistoryGet> data;


  public OrderHistoryRecyclerAdapter(List<OrderHistoryGet> data){
          this.data = data;
   }
    @NonNull
    @Override
    public OrderHistoryRecyclerAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item.xml, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull OrderHistoryRecyclerAdapter.ViewHolder holder, int position) {

      OrderHistoryGet obj = data.get(position);

      holder.order_id.setText(obj.getId()+"");

    }

    @Override
    public int getItemCount() {

        return data.size();
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        private TextView order_id;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            order_id = (TextView) itemView.findViewById(R.id.orderid);

        }
    }
}

Теперь в методе onResponse сделайте это. 

   ....

@Override
public void onResponse(Call<OrderHistoryResponse> call, Response<OrderHistoryResponse> response) {
                Toast.makeText(OrderHistoryActivity.this, "" + response.body().getData(), Toast.LENGTH_SHORT).show();
     runOnUiThread(new Runnable() {
            @Override
            public void run() {
                OrderHistoryRecyclerAdapter adapter = new OrderHistoryRecyclerAdapter(response.body().getData());

      //This recyclerView object should create before,  like      findViewById(R.id.recyclerViewIdinXML)


         RecyclerView.LayoutManager manager=new LinearLayoutManager(getContext());
        ((LinearLayoutManager) manager).setOrientation(LinearLayoutManager.VERTICAL);
        recyclerView.setLayoutManager(manager);
         recyclerView.setAdapter(adapter);


            }
        });
    }

   ...

Вот так.

...
