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"/>
</shape>

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:orientation="horizontal">


        <TextView
            android:id="@+id/zp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_weight="1"
            android:gravity="center"
            android:text="招聘"
            android:textColor="#000"
            android:textSize="18sp" />
        <LinearLayout
            android:layout_weight="7"
            android:layout_width="0dp"
            android:background="#2CCACACA"
            android:layout_marginLeft="10dp"
            android:layout_height="wrap_content">
            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:src="@mipmap/photo5"/>
            <EditText
                android:id="@+id/e1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:background="@android:color/transparent"
                android:maxLength="20"
                android:textSize="13sp"
                android:textColor="#000"
                android:imeOptions="actionSearch"
                android:singleLine="true"
                android:hint="搜索你感兴趣的职位"/>
        </LinearLayout>

    </LinearLayout>

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/r1"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </androidx.recyclerview.widget.RecyclerView>

</LinearLayout>

新建一个列表文件命名为list.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="130dp"
    android:background="@drawable/border2"
    android:layout_marginTop="10dp"
    android:padding="5dp"
    android:orientation="vertical">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <TextView
            android:id="@+id/t1"
            android:layout_weight="1"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:singleLine="true"
            android:padding="10dp"
            android:textSize="15sp"
            android:text="导购"/>
        <TextView
            android:id="@+id/t2"
            android:layout_weight="1"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:gravity="end"
            android:textColor="#078CF6"
            android:textSize="18sp"
            android:text="4k-6k"/>
    </LinearLayout>

        <TextView
            android:id="@+id/t3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:layout_marginLeft="10dp"
            android:textSize="12sp"
            android:text="中专/中技/高中"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/i1"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:padding="10dp"/>
        <TextView
            android:id="@+id/t4"
            android:layout_width="210dp"
            android:layout_height="wrap_content"
            android:text="东莞市创靓家居装饰材料有限公司常平分公司"
            android:layout_gravity="center"
            android:ellipsize="end"
            android:layout_marginLeft="5dp"
            android:singleLine="true"/>
        <TextView
            android:id="@+id/t5"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginLeft="15dp"
            android:text="广东省 - 东莞市"/>
    </LinearLayout>

</LinearLayout>

界面展示

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 {
}

在这里插入图片描述
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
        }
    }
