在从列表视图中的行检查复选框时，也会选择其他几个复选框。 （在android中）

Question

在从列表视图中的行检查复选框时，也会选择其他几个复选框。 （在android中）。有谁知道为什么会出现这个问题？这是我的源代码：

            dbHelper db1 = new dbHelper(WaterPopup.this);

    waterList = new ArrayList<HashMap<String, Object>>();

    map1 = new HashMap<String, Object>();

    Cursor c1 = db1.getMenuDetailsData(SubMenuID);
    c1.moveToFirst();
    while (c1.isAfterLast() == false) {

        if (c1.getString(3).substring(0).equals("I")) {
            map1.put("WaterOptionID", c1.getString(5).substring(0)) ;
              map1.put("CheckBox",cb);
              map1.put("WaterOptionName", c1.getString(0).substring(0));
              map1.put("MinusImg",R.drawable.minus_30+"");
              map1.put("Quantity","1");
              map1.put("PlusImg",R.drawable.plus_30+"");
              map1.put("Currency","$");
              map1.put("Price", c1.getString(2).substring(0));
              map1.put("OrderStatusImg",R.drawable.round_25+"");

            waterList.add(map1);
            map1 = new HashMap<String, Object>();
        }

        c1.moveToNext();
    }
    c1.close(); 


        mSchedule = new SimpleAdapter(WaterPopup.this, waterList, R.layout.waterlistitem,
                new String[] {"WaterOptionID","CheckBox", "WaterOptionName", "MinusImg", "Quantity","PlusImg","Currency", "Price", "OrderStatusImg"}, 
                   new int[] {R.id.wateroptionID_tv,R.id.orderWater_cb, R.id.wateroptionName_tv, R.id.minussign_btn, R.id.Qty_tv, R.id.plusimage_btn,R.id.currency_tv,R.id.price_tv,R.id.orderStatus_btn});
        OrderWaterItem.setAdapter(mSchedule);

Answer 1

SimpleAdapter仅支持TextViews：

构造函数中'to'参数的描述：

“应该在”from“参数中显示列的视图。这些应该都是TextViews 。此列表中的前N个视图将被赋予前N列的值from参数。“

您必须覆盖适配器。这并不难。看这里：
