Я использую пользовательский listview, который имеет 2 разных макета для одного элемента.элементы в пользовательском listview не перерабатываются с новыми данными json android
Мои данные JSON:
{
"status": "success",
"response": [
{
"store_id": "1",
"store_name": "Prashant Stores",
"items": [
{
"item_id": "1",
"item_name": "Kellogs Cornflakes",
"item_price": "75",
"item_size": "500 mg",
"item_quantity": "1",
"item_total": "75",
"delivery_boy_status_id": "3",
"delivery_boy_status": "Delivered",
"is_available": "1"
},
{
"item_id": "2",
"item_name": "Chocos",
"item_price": "75",
"item_size": "1 kg",
"item_quantity": "1",
"item_total": "75",
"delivery_boy_status_id": "3",
"delivery_boy_status": "Delivered",
"is_available": "1"
}
]
},
{
"store_id": "5",
"store_name": "Corner Stores",
"items": [
{
"item_id": "4",
"item_name": "Chocos",
"item_price": "400",
"item_size": "1 kg",
"item_quantity": "1",
"item_total": "400",
"delivery_boy_status_id": "1",
"delivery_boy_status": "To be Collected",
"is_available": "1"
}
]
}
],
"message": ""
}

ш hen scroll my listview Последний элемент в списке не дает мне обновленного значения из данных.
Я вижу значение второго пункта в списке, повторенном для последнего.

Я думаю, вы должны двигаться 'для (int i = 0; i
, если я это сделаю .. th e items count получают увеличение макета при прокрутке –
@karthikkolanji перемещают цикл for вне условия if и записывают его ниже блока else и не забывают писать viewHolder.container.removeAllViews() перед циклом for. –
