在OrderHistoryActivity Activity中，在XML中使用RecyclerView并在OrderHistoryActivity.java中创建对象。

创建item.xml文件

注：它要求你正在使用activity_order_history (OrderHistoryActivity xml文件)的viewHolder错误。<?xml version="1.0" encoding="utf-8"?>

android:orientation="vertical" android:layout_width="match_parent"

android:layout_height="wrap_content">

android:id="@+id/orderid"

android:layout_width="wrap_content"

android:layout_height="wrap_content"/>

现在将OrderHistoryRecyclerAdapter.java修改为：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 {

private List data;

public OrderHistoryRecyclerAdapter(List 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);

}

}

}

现在在onResponse方法中这样做。....

@Override

public void onResponse(Call call, Response 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);

}

});

}

...

就是这样。
