Android 带图片的列表: 列表布局

1，编写xml代码

<?xml version="1.0" encoding="utf-8"?>
<!--
数据 头部
-->
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="智慧校园"
        android:textSize="50dp"
        ></TextView>

        <ListView
            android:id="@+id/android:list"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            />



</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<!--
数据主体
-->

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <ImageView
        android:id="@+id/img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="26sp"/>
        <TextView
            android:id="@+id/info"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textSize="26sp"/>
    </LinearLayout>

</LinearLayout>

2，编写类

package com.example.listviewtest;

import androidx.appcompat.app.AppCompatActivity;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ListView;
import android.widget.SimpleAdapter;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class MainActivity2 extends ListActivity {
    private ListView list;
    private String[] title = {"软件2019级一班","软件2019级二班","软件2019级三班","软件2019级四班","软件2019级五班","软件2019级六班",};
    private String[] info = {"java","html","css","linux"};
    private  int[] imgId ={R.drawable.icon1,R.drawable.icon2,R.drawable.icon3,R.drawable.icon4};

    private List<Map<String,Object>> data;


     private SimpleAdapter adapter;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);
        list = getListView();

        adapter = new SimpleAdapter(this,getData(),R.layout.list_item,new String[]{"img","title","info"},new int[]{R.id.img,R.id.title,R.id.info});
        list.setAdapter(adapter);

    }

    private  List<Map<String,Object>> getData(){
//        data 实例化
        data = new ArrayList<Map<String,Object>>();

        for (int i = 0;i < imgId.length;i++){
            Map<String,Object> map = new HashMap<String, Object>();
            map.put("img",imgId[i]);
            map.put("title",title[i]);
            map.put("info",info[i]);

//            三个数据放入map
            data.add(map);
        }


        return  data;

    }
}
