ListView Checkbox取值问题，贴代码，求前辈解决

Question

贴一下代码：
望各位前辈指点啊，代码实现了获取手机联系人的功能，但现在面临的问题是如何防止list滑动时混乱的发生，以及如何取listview值？public class Getcontacts extends Activity {
   
    private ListView contactList;
        
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.getcontacts);
   
    contactList = (ListView) findViewById(R.id.contactList);
    contactList.setItemsCanFocus(false);
    contactList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    //cb=(CheckBox)findViewById(R.id.contactsCheckBox);  
   
    getContactsList();
   
    }
   
   
    private void getContactsList() {
   
        ArrayList<HashMap<String, Object>> contactsListItem = new ArrayList<HashMap<String, Object>>();      
         
        Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);     
        while (cursor.moveToNext())   
        {   
         HashMap<String, Object> map = new HashMap<String, Object>();
         String phoneName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
         map.put("nameTxt", phoneName);
         
         String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));  
         String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));  
           
            if (hasPhone.compareTo("1") == 0)   
            {  
                Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null);      
                while (phones.moveToNext())   
                {     
                 String strphoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));      
                 String  phoneNumber="";   
                         phoneNumber+=strphoneNumber+" ";
                         map.put("numberTxt", phoneNumber);
                 }      
                phones.close();      
            }      
   
            contactsListItem.add(map);
    }
        SimpleAdapter contactListAdapter = new SimpleAdapter(this, contactsListItem,R.layout.contactslistitem,new String[] {"nameTxt", "numberTxt"}, new int[] {R.id.nameTxt,R.id.numberTxt});
        //ArrayAdapter<HashMap<String, Object>> contactListAdapter = new  ArrayAdapter<HashMap<String, Object>>(this, android.R.layout.simple_list_item_multiple_choice, contactsListItem);        contactList.setAdapter(contactListAdapter);
      
        cursor.close();  
        
        contactList.setOnItemClickListener(new OnItemClickListener() {
            
            @Override
            public void onItemClick(AdapterView<?>parent, View view, int position, long id)
            {
               
             //如何取值？   
            }            
            
        });
        
    }}

Answer 1

试试  @Override
  public void onItemClick(AdapterView<?>parent, View view, int position, long id)
  {
    
    HashMap<String, Object> phonernumber=  contactsListItem.get(position);
  }

Answer 2

你在getContactsList中保存一个值得数组,假设为 val_arr (定义为成员变量)
然后再onItemClick中, 用哪个position这个position就是第几个item被调用.var_arr[position]就是你要的值. ok?

Answer 3

HashMap<String, Object> phonernumber= contactsListItem.get(position);
