Android ListView详解(4)

                R.layout.personitem, 
                new String[] { "personid", "name", "age" }, new int[]{R.id.personid,R.id.personname,R.id.personage}); 
        listView.setAdapter(simpleAdapter); 
         
        /*
         * 这是通过游标在ListView控件上显示数据,需要注意的是主键字段名id应改为_id，否则会报错
        Cursor cursor = personService.getRawScrollData(0, 10);
        SimpleCursorAdapter simpleCursorAdapter = new SimpleCursorAdapter(this, R.layout.personitem,
                cursor,
                new String[] { "_id", "name", "age" }, new int[]{R.id.personid,R.id.personname,R.id.personage});
        listView.setAdapter(simpleCursorAdapter);
        */ 
        //为item选项设置监听 
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
 
            public void onItemClick(AdapterView<?> parent, View view, int position, 
                    long id) { 
                ListView listView = (ListView)parent; 
                Map<String,String> map = (HashMap<String, String>)listView.getItemAtPosition(position); 
                Log.i("DBActivity", map.get("age")); 
            } 
             
        }); 
 
    } 
}
