How i get the OnGroupExpandListener() & OnChildClickListener() ?

When creating an ExpandableRecyclerAdapter.ListItem, is it possible to set a property so that it is expanded by default, instead of calling expandItems on each of them after finish with setItems()?

Thanks

Hi there,
Thanks for your prompt response.

I'm going to show users a selected state for children rows. but Library each time user open parent row, insert new row and change the position! then when user scroll the list, may have see multiple row is selected!!

I'm using SparseBooleanArray to map integer to Boolean for this goal. but when position had change this solution is worthless!

How you handle it?

like this

Hi there,

First, thank you very much for your great library, it saves me a lot of time and it is really tough and stable !

However, I'm encountering an issue in production on version 0.9.3. I can't reproduce it on my side but perhaps this stack trace could help you ? The index of 4 is just an example, it apparently happen in many situations.

Fatal Exception: java.lang.IndexOutOfBoundsException: Index: 4, Size: 4 at java.util.ArrayList.get(ArrayList.java:437) at com.innodroid.expandablerecycler.ExpandableRecyclerAdapter.isExpanded(ExpandableRecyclerAdapter.java:160) at com.innodroid.expandablerecycler.ExpandableRecyclerAdapter.toggleExpandedItems(ExpandableRecyclerAdapter.java:91) at com.innodroid.expandablerecycler.ExpandableRecyclerAdapter$HeaderViewHolder.handleClick(ExpandableRecyclerAdapter.java:78) at com.innodroid.expandablerecycler.ExpandableRecyclerAdapter$HeaderViewHolder$1.onClick(ExpandableRecyclerAdapter.java:72) at android.view.View.performClick(View.java:6312) at android.view.View$PerformClick.run(View.java:24811) at android.os.Handler.handleCallback(Handler.java:790) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:171) at android.app.ActivityThread.main(ActivityThread.java:6649) at java.lang.reflect.Method.invoke(Method.java) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:547) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:824)

There is no particular device affected by this issue, affecting all brands, on Android 5->8 during the last 30 days.

Do you have any idea on why or how this could happen?

Again, thank you for your great work, and in advance for your help :).

Hi,

I need to close the previously opened parentview in list items.

For eg:

1. I opened first parent view
2. when i click 2 parent view..i need to close 1 parent view.

This is my requirement ...how to achieve this?

Hello,

I have implemented the expandable Recycler view & its working fine. I am having a functionality that I need to refresh the child items with respect to parent item click. How to achieve it?

Greetings!

I'm trying to use this lib with GridLayoutManager.
But when I've done this, the result was not as I expected.

When all tabs are expanded thats fine. In other cases it's looked wired.
I use this code in my Activity.

final GridLayoutManager manager = new GridLayoutManager(this, 2);
        recycler.setLayoutManager(manager);

        final PeopleAdapter adapter = new PeopleAdapter(this);
        recycler.setAdapter(adapter);

        manager.setSpanSizeLookup(new GridLayoutManager.SpanSizeLookup() {
            @Override
            public int getSpanSize(int position) {
                return adapter.isHeader(position) ? manager.getSpanCount() : 1;
            }
        });

Hi there
There is a issue with this adapter, I've to get categories and their subcategories from rest API.
As usual after parsing and making my List and assign that to Adapter, I use notifyDatasetChanged() method to notify Adapter.
Issue is there! Adapter does not recognize the change!

another odd action: notifyDatasetChanged() close the open parent but the arrow still remain in it's open state! ( When I populated the adapter with fake data like yours sample app ).

Is there any custom method for this?

I have use your class for creating an expandable list and its work nice. I changed that arrow rotate 180 degrees, instead of 90, but now when i scroll down and scroll back (list have about 20 items) arrow is not in rotating position.

can i use it on api level 14 or below?

please help
