And for the second, you should update you data form your callback (onDataChange). So, inside your Adapter class create update method, which calls notifyDataSetChange, like this(for example):
(it's kotlin, but if you have any questions - ask)
fun updateData(newData: ArrayList<String>) {
itemsExample = newData
notifyDataSetChanged()
}(it's kotlin, but if you have any questions - ask)

oh, how long haven't i worked with filter :D

i think i am doing that take a look inside the filter method
Does it work?
J
Does it work?
the filter code works but the published results seems to be the problem i honestly cannot track what causes the adapter to display wrong data. I logged the filtered data going inside the mFilteredList and it seems to be accurate but after getting passed idk what happens.
J
Here is the filter

idk what is stack trace but here the error log, i knew it will crash since the list is not yet populated
So learn basic Java before jumping into Android and try googling error message before asking in a chat.

i understand the error here, i already told him it would cause me a crash if i'd place the adapter initialization before the firebase code

Ему, по факту, надо просто обновлять его список через коллбек, а он создавал для этого несколько адаптеров, когда дата менялась

how do you get new data for your adapter?
J
After being filtered the new arraylist data is then saved again to mFilteredList preceeded with notifyDataSetChanged
V
how do you get your unfiltered data?
J
firebase? using model? ArrayList<MyModel>?

you have heroes list, and filteredList.
the first - you have to get heroeslist. You have to create something like this:
and call it from onDataChange
