//效果图

简单的listview，关键是ArrayAdapter中布局和数据的适配。android.R.layout.simple_list_item_1系统自带的样式，可以根据自己的要求更改布局样式。List<String>ls = new ArrayList<String>() 用于显示的数据。

//SimpleAdapter 适配Listview

//layout

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="horizontal" android:layout_width="match_parent"

android:layout_height="match_parent">

<ImageView

android:id="@+id/img2"

android:layout_height="wrap_content"

android:layout_width="wrap_content"

/>

<LinearLayout

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:orientation="vertical">

<TextView

android:id="@+id/title2"

android:layout_width="wrap_content"

android:layout_height="wrap_content" />

<TextView

android:id="@+id/price"

android:layout_width="wrap_content"

android:layout_height="wrap_content"/>

</LinearLayout>

</LinearLayout>

//关键代码设置listview

SimpleAdapter adapter1 =new SimpleAdapter(this,lm,R.layout.simple2, new String[]{"title","img","price"},new int[]{R.id.title2,R.id.img2,R.id.price});

setListAdapter(adapter1);

//得到数据

public List<Map<String, Object>> getData2()

{

Map<String,Object>value =new HashMap<String,Object>();

List<Map<String,Object>>lm =new ArrayList<Map<String,Object>>();

value.put("title","苹果");

value.put("img",R.drawable.aphone);

value.put("price","价格：5800");

lm.add(value);

value =new HashMap<String,Object>();

value.put("title", "三星");

value.put("img",R.drawable.sphone);

value.put("price","价格：4800");

lm.add(value);

value =new HashMap<String,Object>();

value.put("title","华为");

value.put("img",R.drawable.hphone);

value.put("price","价格：6000");

lm.add(value);

return lm;

}

//SimpleCursorAdapter适配Listview 用于数据库数据的显示

//关键代码

//获得一个指向系统通讯录数据库的Cursor对象获得数据来源

Cursor cursor = getContentResolver().query(Contacts.People.CONTENT_URI,null,null,null,null);

startManagingCursor(cursor);

//实例化列表适配器

ListAdapter la = new SimpleCursorAdapter(this,android.R.layout.simple_list_item_2,cursor,new String[]{Contacts.People.NAME,Contacts.People.NUMBER},new int[]{android.R.id.text1,android.R.id.text2});

setListAdapter(la);
