Android studio ListView应用设计

一、添加ListView控件：

复制代码

<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：

复制代码

<?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"
    android:orientation="vertical"
    android:padding="5dp">

    <ImageView
        android:id="@+id/icon"
        android:layout_width="80dp"
        android:layout_height="64dp"
        android:layout_centerInParent="false"
        android:src="@drawable/china_icon" />

    <TextView
        android:id="@+id/TextView"
        android:layout_width="80dp"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="china"
        android:textSize="18sp" />

</LinearLayout>

四、Adapter文件：

五、MainActivity.java文件：

复制代码

    context = MainActivity.this;
    listView = findViewById(R.id.listView);

    countryList = new ArrayList<Country>();
    countryList.add(new Country("china",R.drawable.china_icon));
    countryList.add(new Country("germany",R.drawable.germany_icon));
    countryList.add(new Country("finland",R.drawable.finland_icon));
    countryList.add(new Country("mexico",R.drawable.mexico_icon));
    countryList.add(new Country("india",R.drawable.india_icon));

    countryAdapter = new CountryAdapter((List<Country>) countryList,context);
    listView.setAdapter(countryAdapter);

    listView.setOnItemClickListener(MainActivity.this);
}

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
    Toast.makeText(context,"您点击了第" + i + "项",Toast.LENGTH_SHORT).show();
}
