定制ListView的界面

一、步骤

1.初始化数据；

2.提供一个自己定制的Adapte；

3.找到ListView控件；

4.给ListView设置适配器

二、直接上代码

1.Fruit.java

package com.zhc.listviewtest;public class Fruit {private String name;//成员变量nameprivate int imageId;//这个构造函数在MainActivity中的初始化水果数据initFruits的会被重写，参数重新赋值。public Fruit(String name, int imageId) {this.name = name;//将参数name赋值给成员变量namethis.imageId = imageId;}public String getName() {return name;}public int getImageId() {return imageId;}}

2.fruit_item.xml

<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" >    <ImageView        android:id="@+id/fruit_image"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <TextView        android:id="@+id/fruit_name"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:layout_marginLeft="10dp" /></LinearLayout>

3.FruitAdappter.java

package com.zhc.listviewtest;import java.util.List;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ArrayAdapter;import android.widget.ImageView;import android.widget.TextView;public class FruitAdappter extends ArrayAdapter<Fruit> {private int resourceId;//重写父类ArrayAdapter的一组构造函数，用于将上下文、ListView子项布局的id和数据传递进来。public FruitAdappter(Context context,  int textViewResourceId,List<Fruit> objects) {super(context, textViewResourceId, objects);resourceId = textViewResourceId;//textViewResourceId的值是由MainActivity里面的构造函数（new FruitAdappter（））传过来的R.layout.fruit_item}//重写父类的getView方法，这个方法在每个子项被滚动到屏幕内的时候会被调用。@Overridepublic View getView(int position, View convertView, ViewGroup parent) {Fruit fruit=getItem(position);//获取当前项的Fruit实例View view = LayoutInflater.from(getContext()).inflate(resourceId, null);ImageView fruitImage = (ImageView) view.findViewById(R.id.fruit_image);TextView fruitName =(TextView) view.findViewById(R.id.fruit_name);fruitImage.setImageResource(fruit.getImageId());//设置显示的图片fruitName.setText(fruit.getName());//设置显示的文字return view;}}

4.MainActivity.java

package com.zhc.listviewtest;import java.util.ArrayList;import java.util.List;import android.os.Bundle;import android.widget.ListView;import android.app.Activity;public class MainActivity extends Activity {private List<Fruit> fruitList= new ArrayList<Fruit>();@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//1.初始化水果数据initFruits();//2.提供一个自己定制的Adapter（跟android提供的适配器ArrayAdapter的原理是一样的）FruitAdappter adapter = new FruitAdappter(MainActivity.this, R.layout.fruit_item, fruitList);//3.找到ListView控件ListView listView = (ListView) findViewById(R.id.list_view);//4.给ListView设置适配器listView.setAdapter(adapter);}private void initFruits() {Fruit apple=new Fruit("Apple",R.drawable.ic_launcher);fruitList.add(apple);Fruit banana=new Fruit("Banana",R.drawable.ic_launcher);fruitList.add(banana);Fruit orange=new Fruit("Orange",R.drawable.ic_launcher);fruitList.add(orange);Fruit watermelon=new Fruit("Watermelon",R.drawable.ic_launcher);fruitList.add(watermelon);Fruit pear=new Fruit("Pear",R.drawable.ic_launcher);fruitList.add(pear);Fruit grape=new Fruit("Grape",R.drawable.ic_launcher);fruitList.add(grape);Fruit pineapple=new Fruit("Pineapple",R.drawable.ic_launcher);fruitList.add(pineapple);Fruit strawberry=new Fruit("Strawberry",R.drawable.ic_launcher);fruitList.add(strawberry);Fruit cherry=new Fruit("Cherry",R.drawable.ic_launcher);fruitList.add(cherry);Fruit mango=new Fruit("Mango",R.drawable.ic_launcher);fruitList.add(mango);Fruit mango1=new Fruit("Mango1",R.drawable.ic_launcher);fruitList.add(mango1);Fruit mango2=new Fruit("Mango2",R.drawable.ic_launcher);fruitList.add(mango2);Fruit mango3=new Fruit("Mango3",R.drawable.ic_launcher);fruitList.add(mango3);Fruit mango4=new Fruit("Mango4",R.drawable.ic_launcher);fruitList.add(mango4);}}

5.activity_main.java

<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"    >    <ListView        android:id="@+id/list_view"        android:layout_width="match_parent"        android:layout_height="match_parent"        /></RelativeLayout>

三、最终的效果图
