Android RecycleView搜索列表内容(OkHttp网络请求)
1.添加网络权限
<uses-permission android:name="android.permission.INTERNET"/>
2.导入第三方库
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.squareup.okhttp3:okhttp:3.12.1'
debugImplementation 'com.squareup.okhttp3:logging-interceptor:3.12.1'
implementation 'com.google.code.gson:gson:2.8.5'
implementation 'com.github.bumptech.glide:glide:4.9.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
//添加CircleImageView依赖
implementation 'de.hdodenhof:circleimageview:2.1.0'
3.界面布局
自定义列表样式，在drawable文件上新建一个名为border.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="20dp"
android:topRightRadius="20dp"
android:bottomRightRadius="20dp"
android:topLeftRadius="20dp"
android:bottomLeftRadius="20dp"/>
<stroke
android:color="#CDCDCD"
android:width="1dp"/>

<androidx.recyclerview.widget.RecyclerView
android:id="@+id/r1"

4.功能实现
定义一个DateModel类
解析JSON数据，进行网络请求
public class DateModel implements Serializable {
}
新建一个Adapter类
package com.example.note5;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import com.bumptech.glide.Glide;
import java.util.List;
import de.hdodenhof.circleimageview.CircleImageView;
public class Adapter extends RecyclerView.Adapter<Adapter.ViewHolder>{
private List<DateModel.DataBean> list;
private MainActivity mainActivity;
public Adapter(List<DateModel.DataBean> list,MainActivity mainActivity)
{
this.list=list;
this.mainActivity=mainActivity;
}
@NonNull
@Override
public Adapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view= LayoutInflater.from(parent.getContext()).inflate(R.layout.list,parent,false);
ViewHolder viewHolder=new ViewHolder(view);
return viewHolder;
}
@Override
public void onBindViewHolder(@NonNull Adapter.ViewHolder holder, int position) {
DateModel.DataBean dataBean=list.get(position);
holder.t1.setText(dataBean.getJobs_name());
holder.t2.setText(dataBean.getWage());
holder.t3.setText(dataBean.getEducation_str());
holder.t4.setText(dataBean.getCompany_name());
holder.t5.setText(dataBean.getDistrict_str());
Glide.with(mainActivity).load(dataBean.getCompany_logo()).into(holder.i1);
}
@Override
public int getItemCount() {
return list.size();
}
public class ViewHolder extends RecyclerView.ViewHolder
{
private TextView t1,t2,t3,t4,t5;//文本框id
private CircleImageView i1;
public ViewHolder(@NonNull View itemView) {
super(itemView);
t1=itemView.findViewById(R.id.t1);//绑定id
t2=itemView.findViewById(R.id.t2);//绑定id
t3=itemView.findViewById(R.id.t3);//绑定id
t4=itemView.findViewById(R.id.t4);//绑定id
t5=itemView.findViewById(R.id.t5);//绑定id
i1=itemView.findViewById(R.id.i1);//绑定id
}
