سلام به دوستان برنامه نویس اندرویدی.
چندی پیش درخواست کمک برای نشون دادن داده ها توی لیست ویوو با استفاده از Async Task فرستادم که جوابی نشنیدم .
اما اون کد رو نوشتم و بدون خطا اجرا شد اما هیچی توی لیست ویو نشون نمیده. دوستان اگه کسی میدونه چرا این خطا رو میده بهم بگه لطفا خیلی ضروریه . واسه پروژست.
این logcat هست :
