需要在Android的Listview中從getadapter獲取逐列值

我已經使用下面給出的代碼填充了listview，但是我無法從列表中取回值，因爲getadpter編寫了一個對象。從對象中我無法獲得逐個列值。需要在Android的Listview中從getadapter獲取逐列值

代碼填充列表視圖：

String pkManifest = manifest.pkManifestNo; 
     ArrayList<HashMap<String, String>> alist = new ArrayList<HashMap<String, String>>(); 
     HashMap<String, String> map = new HashMap<String, String>(); 
     manifest_helper = new manifest_helper(this); 

    cursor = manifest_helper.GetDeliveriesAgainstManifest(pkManifest); 
    cursor.moveToFirst(); 

    for (int i = 0; i < cursor.getCount(); i++) { 

     map = new HashMap<String, String>(); 
     map.put("Deliv_Address", 
       cursor.getString(cursor.getColumnIndex("Address"))); 
     map.put("Deliv_Time", 
       cursor.getString(cursor.getColumnIndex("Time"))); 
     map.put("Deliv_Order", 
       cursor.getString(cursor.getColumnIndex("DeliveryOrder"))); 
     map.put("Deliv_IsCustomerPickup", 
       cursor.getString(cursor.getColumnIndex("IsCustomerPickup"))); 
     map.put("Deliv_FKDeliveryStatus", 
       cursor.getString(cursor.getColumnIndex("FKDeliveryStatus"))); 
     map.put("Deliv_PKDelivery", 
       cursor.getString(cursor.getColumnIndex("PKDelivery"))); 
     alist.add(map); 
     cursor.moveToNext(); 
    } 
    sd = new SimpleAdapter(this, alist, R.layout.deliveries_list_row, 
      new String[] { "Deliv_Address", "Deliv_Time", 
        "Deliv_Order", "Deliv_IsCustomerPickup", 
        "Deliv_FKDeliveryStatus", "Deliv_PKDelivery" }, 
      new int[] { R.id.tv_Deliv_Address, R.id.tv_Deliv_Time, 
        R.id.tv_Deliv_Order, 
        R.id.tv_Deliv_IsCustomerPickup, 
        R.id.tv_Deliv_FKDeliveryStatus, 
        R.id.tv_Deliv_PKDelivery }); 
    //selectedAdapter = new SelectedAdapter(this, 0, alist); 
    //selectedAdapter.setNotifyOnChange(true); 

    ListDeliveries.setAdapter(sd);

代碼用於獲取關於onItemSelected值是這樣寫的：

private OnItemSelectedListener mDeviceSelectedListener = new OnItemSelectedListener() { 
    public void onItemSelected(AdapterView<?> av, View v, int arg2,long arg3) { 
    Object o = av.getAdapter().getItem(arg2); 
     String keyword = o.toString(); 
    MessageBox("You selected: " + keyword);   
}

private OnItemClickListener mDeviceClickListener = new OnItemClickListener() { 
     public void onItemClick(AdapterView<?> av, View v, int arg2, long arg3) { 
      HashMap result = (HashMap) av.getAdapter().getItem(arg2); 
      pkDelivery = result.get("Deliv_PKDelivery").toString(); 
      pbDeliveryOrder=result.get("Deliv_Order").toString(); 

      isCustomerPickup=result.get("Deliv_IsCustomerPickup").toString(); 
      if ("false".equals(isCustomerPickup)) 
      {    
       customerPickup="false"; 
       pbPickUp="false";   
      } 
      else 
      { 
       customerPickup="true"; 
       pbPickUp="true"; 
      } 
      launchDelivery_header(pkDelivery); 

     } 

    };

這可以通過獲取適配器值到完成哈希映射並逐個獲取它
