throwIndexOutOfBoundsException

Hi

I have the same issue with this code.

The line where the code throws is the following

public void addItem(int position, Atividades model) {
        atividadesList.add(position, model);
        notifyItemInserted(position);
    }

The log

It looks like notifyItemInstered is not called :/

Error while opening the project

Hello, the project showing the following error while I try to open it.

generate mBinding

hi
I found something in your project. your layout with data tag is item_example but in your main activity code you write private ActivityMainBinding mBinding;
but i found that it should be like this private ItemExampleBinding mBinding;
And becuz of that mBinding.recyclerView cant find recyclerView.
i think something is missing.
Thank you for your help
I'm waiting for the answer.

ItemExampleBinding

Hi
ItemExampleBinding class is not exists !!!

Do you really need to have 3 quadratic algorithms instead of notifyDataSetChanged()?

In your ExampleAdapter class you used 3 functions, that is quadratic

one of them is
`

private void applyAndAnimateAdditions(List<ExampleModel> newModels) {
    for (int i = 0, count = newModels.size(); i < count; i++) {
        final ExampleModel model = newModels.get(i);
        if (!mModels.contains(model)) {
            addItem(i, model);
        }
    }
}

`

Since mModels is a List, you have O(n) when use contains() method (so may be you should change it to HashSet).
Is it really beneficial to use your approach?
If you have 1000 items, you will have to go through 1000000 items two times.
But if you use notifyDataSetChanged(), you only need to redraw only visible items and walk through 1000 items only.
Or may be I don't understand something.

cannot resolve symbol ItemExampleBinding

When I open your project, it occurs an error in exampleadapter at ItemExampleBinding. I don't know why

Slow algorithm with Big Array List

Hi! Great project, I really do appreciate your work!

I have a performance problem with your filtering algorithm if I use a big ArrayList (almost 400k words) to filter.

Precisely, it lags and it takes some time to filter the word I'm searching for.

Do you have any suggestion on that?
That might be useful for a lot of people dealing with a lot of entries.

Thank you and have a nice day!

IndexOutOfBoundsException

When I try to delete text from the searchView, it throws a IndexOutOfBoundsException.

Searchable-RecyvlerView with GridView

Hello I implemented your demo and it works fine, but there are moments that the animation messes up...

I've done two screenshoots refering the problem take a look :

When I type something and the result is : http://i.imgur.com/Evsbf6i.png

BUT when I press back to hide the keyboard it goes : http://i.imgur.com/MoLJ8Lm.png

Do you know what exactly is the problem? Also I've oppened a post on Stackoverflow that is about your post : http://stackoverflow.com/questions/34889264/recyclerview-add-emptyview

Thanks.

Clicking items

Hi, I'm researching your Searchable-RecyclerView but I would like make clickable items (filtered o not filtered). So I implement View.OnClickListener in ExampleAdapter but I'm not sure if it is the best approach to your project. If you have to add, this feature what do you think is the right way make it possible?

Regards,

Fragment doesn't show recycler view items by default.

I followed your code to make a filter in my fragment. Here is the stackoverflow question I asked. I am sorry to bother you here but I couldn't find a way to get to contact you for this problem.

Extra items appear when searching and persist

Whenever I trigger the search view and type something in, items disappear as expected but then new items (regurgitated from the previous and visible ones) appear to replace them and don't go away after exiting the Search view.

These new items also refuse to disappear when I relaunch the Search view and type in a query that would hide them.

I have absolutely NO idea what code could be causing the problem.

Multiple comparators not possible

EDIT:
Changing my Google searches around a bit, I realised I don't need another comparator but additional filters - https://stackoverflow.com/a/37207601/956975

---

Hi, this is perhaps more a question than an issue - apologies if I'm messing with your Github stats by posting this as an "issue".

Thanks for this great solution to the problem of searching in a RecyclerView. It's easy, slick and just works!

BUT, I would like to be able to not just compare one field of a model.

In your example, you're comparing the text field of your Model class. The ALPHABETHICA_COMPARATOR does this in the activity and this comparator is sent to the Adapter.

How can I create a second comparator in the activity, which is then passed to the Adapter and then the user is able to search by text field of the model or id field of the model.

I hope this makes sense.
