when i used this it remove one element with animation

{

    notificationItems.remove(0);

    adapterForNotification.notifyItemRemoved(0);                        

    adapterForNotification.notifyItemRangeRemoved(0,count-1);

}

when i used this it remove all element without animation

count = adapter.getItemCount();

for(int i = 0 ; i < count; ++i){

    notificationItems.remove(0);

    adapterForNotification.notifyItemRemoved(0);

    adapterForNotification.notifyItemRangeRemoved(0,count-1)

}

count = adapter.getItemCount();



for (int i = 0 ; i < count; ++i){

    notificationItems.remove(0);

}

adapterForNotification.notifyItemRangeRemoved(0, count-1)

You shouldn't be using both notifyItemRemoved() and notifyItemRangeRemoved(). Only use one at a time.

If you want to remove one item:

notificationItems.remove(index);

adapterForNotification.notifyItemRemoved(index);

If you want to remove all items:

int origCount = notificationItems.size();

notificationItems.clear();

adapterForNotification.notifyItemRangeRemoved(0, origCount - 1);

If you want to remove a range of items:

notificationItems.subList(startIndex, endIndex).clear();

adapterForNotification.notifyItemRangeRemoved(startIndex, endIndex);

EDIT:

If you want to remove each item one by one and show the removal animation for each, try this:

for (int i = 0; i < notificationItems.size(); i++) {

    notificationItems.remove(i);

    adapterForNotification.notifyItemRemoved(i);

}
