使用SimpleAdapter填充ListView

在Android中，ListView是用来显示一个列表的控件。每一行列表都是一个独立的元素。这种控件既可以方便的显示从系统中其他应用读取出来的数据，也可独立的为各行元素设置监听器。

效果图

1、先定义item

xml version="1.0" encoding="utf-8"?>
<LinearLayout
 xmlns:android=""
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
 <TextView
   android:layout_width="80dip"
   android:layout_height="wrap_content"
   android:id="@+id/personid"
 />
 <TextView
   android:layout_width="100dip"
   android:layout_height="wrap_content"
   android:id="@+id/name"
/>
 <TextView
   android:layout_width="fill_parent"
   android:layout_height="wrap_content"
   android:id="@+id/amount"
 />
LinearLayout>

2、通过适配器把数据绑定到listview中，点击某一行数据显示编号

方式一：

List<HashMap<String, Object>> data=new ArrayList<HashMap<String,Object>>();
       for(Person person :persons){
         HashMap<String, Object> hashMap=new HashMap<String, Object>();
         hashMap.put("id", person.getPersonId());
         hashMap.put("name", person.getName());
         hashMap.put("amount", person.getAmount());
         data.add(hashMap);
 }
SimpleAdapter adapter=new SimpleAdapter(this,data,R.layout.item,new String[]{"id","name","amount"},new int[]{R.id.personid,R.id.name,R.id.amount});              listView.setAdapter(adapter);
 listView.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView> parent, View view,
   int position, long id) {
   ListView myListView=(ListView)parent;
   HashMap<String, Object> item=(HashMap<String, Object>)myListView.getItemAtPosition(position);
   Toast.makeText(DBActivity.this, item.get("id").toString() , Toast.LENGTH_SHORT).show();
    }
  }
);

方式二：用游标的方式

Cursor cursor=personService.getCursor(0, 15);        //要求字段中要有_id  设计表的时候的主键为_id
SimpleCursorAdapter cursorAdapter=new SimpleCursorAdapter(this,R.layout.item,cursor,new String[]{"_id","name","amount"},new   int[]{R.id.personid,R.id.name,R.id.amount});
listView.setAdapter(cursorAdapter);
listView.setOnItemClickListener(new OnItemClickListener(){
/**
 * parent当前所点击的listview对象
 * view当前所点击的条目
*/
@Override
 public void onItemClick(AdapterView> parent, View view,
   int position, long id) {
   ListView myListView=(ListView)parent;
   Cursor data=(Cursor)myListView.getItemAtPosition(position);//根据位置移动游标
   int m=data.getInt(data.getColumnIndex("_id"));
   Toast.makeText(DBActivity.this, String.valueOf(m) , Toast.LENGTH_SHORT).show();
    }
  }
);
