Android studio ListView应用设计

一、添加ListView控件：

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    tools:layout_editor_absoluteX="1dp" />

二、类文件Country.java：

package com.july.listviewapp;

public class Country {
    private String name;
    private int icon;


    public Country(String name,int icon){
        this.name = name;
        this.icon = icon;
    }

    public String getName(){
        return name;
    }

    public void setName(String name){
        this.name = name;
    }

    public int getIcon(){
        return  icon;
    }

    public void setIcon(int icon){
        this.icon = icon;
    }

}

三、子布局文件：

<?xml version="1.0"
