ListView作为Android最常用但是却最难用的控件之一,有很多神奇的用法.我之前也有写过一个例子,稍微不那么简单了一点.
[Android原生item的伸缩效果]:http://www.cnblogs.com/stareblankly/p/4958062.html

• 简单的ListView的应用.

private Integer[] data={1,1,1,1,1,1,1,1,1,1,1,1,1,1,1};@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_main);ArrayAdapter<Integer> adapter=new ArrayAdapter<Integer>(MainActivity.this, android.R.layout.simple_list_item_1,data);((ListView)findViewById(R.id.lv)).setAdapter(adapter);}

• 定制ListView界面
  1.我们新建一个furit_item.xml作为我们自定义listview的item.

<?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" ><ImageViewandroid:id="@+id/furit_image"android:layout_width="wrap_content"android:layout_height="wrap_content" /><TextViewandroid:id="@+id/fruit_name"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center"android:layout_marginLeft="10dp" /></LinearLayout>

2.然后我们新建一个Furit.class作为数据适配的实体类.

public class Fruit {private String name;private int imageId;public String getName() {return name;}public void setName(String name) {this.name = name;}public int getImageId() {return imageId;}public void setImageId(int imageId) {this.imageId = imageId;}public Fruit(String name, int imageId) {super();this.name = name;this.imageId = imageId;}
}

3.新建一个FruitAdapter.class适配器用来适配listview.

public class FruitAdapter extends ArrayAdapter<Fruit>{private int resourceid;public FruitAdapter(Context context, int textViewResourceId,List<Fruit> objects) {super(context,textViewResourceId, objects);resourceid=textViewResourceId;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {Fruit fruit=getItem(position);View view=LayoutInflater.from(getContext()).inflate(resourceid, null);TextView tv=(TextView) view.findViewById(R.id.fruit_name);ImageView iv=(ImageView) view.findViewById(R.id.furit_image);iv.setImageResource(fruit.getImageId());tv.setText(fruit.getName());return view;}
}

4.然后初始化我们要显示的数据.

private List<Fruit> fruitList=new ArrayList<Fruit>();Fruit fruit=new Fruit("1", R.drawable.ic_launcher);
fruitList.add(fruit);
fruit=new Fruit("2", R.drawable.ic_launcher);
fruitList.add(fruit);
fruit=new Fruit("3", R.drawable.ic_launcher);
fruitList.add(fruit);
......

5.最后就只剩下使用了.

protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);init();FruitAdapter adapter=new FruitAdapter(this, R.layout.fruit_item, fruitList);((ListView)findViewById(R.id.lv)).setAdapter(adapter);}

• ListView的item的点击事件

((ListView)findViewById(R.id.lv)).setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {Fruit fruit=fruitList.get(position);Toast.makeText(MainActivity.this, fruit.getName(), Toast.LENGTH_SHORT).show();}});
