Android学习第三天--listview方式七

跟六有点不同

主xml

<RelativeLayout 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"
    tools:context=".MainActivity" >

<ListView
        android:id="@+id/listview1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

</RelativeLayout>

放置内容的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="match_parent" >

    <ImageView
        android:id="@+id/iv_headid"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

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

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

</LinearLayout>

实体类

package cn.core.entity;

import java.util.HashMap;
import java.util.Map;

public class Students {
    private Integer stuId;
    private String stuName;
    private String stuTelephone;
    private Map<String,String> map;
    private Integer stuHead;
    
    public Students() {
        super();
    }
    public Students(Integer stuId, String stuName, String stuTelephone, Integer stuHead) {
        super();
        this.stuId = stuId;
        this.stuName = stuName;
        this.stuTelephone = stuTelephone;
        this.stuHead = stuHead;
    }




    public Map<String,String> getMap() {
        
        map =new HashMap<String,String>();
        map.put("stuHead", String.valueOf(stuHead));
        map.put("stuName", stuName);
        map.put("stuTelephone", stuTelephone);        
        
        return map;
    }
    
    
    
    public Integer getStuId() {
        return stuId;
    }
    public void setStuId(Integer stuId) {
        this.stuId = stuId;
    }
    public String getStuName() {
        return stuName;
    }
    public void setStuName(String stuName) {
        this.stuName = stuName;
    }
    public String getStuTelephone() {
        return stuTelephone;
    }
    public void setStuTelephone(String stuTelephone) {
        this.stuTelephone = stuTelephone;
    }
    
}
