Calling notifyDatasetChanged on original Adapter inside RecyclerViewMaterialAdapter

[Mithrandir21]

I have been having an issue when I call the "notifyDataSetChanged()" directly on the original adapter (RecyclerView.Adapter) passed to the RecyclerViewMaterialAdapter. Nothing seems to happen. If I call the function on the wrapper, it works fine, but not on the original adapter given to the wrapper.

What could be the reason for this?

I have this issue too :(. I 'm trying to refresh data and it doesn't work. Only the last item in list is refreshed, other are in first state. Is RecyclerViewMaterialAdapter bad ?

[Mithrandir21]

I solved my issue by holding a reference to the original adapter (the one wrapped inside the RecyclerViewMaterialAdapter) and calling the "notifyDataSetChanged()" on that.

BUT the RecyclerViewMaterialAdapter seems to have a some internal functions starting with "mvp_" that call similar functions in the wrapped adapter. I think you should try to call "mvp_notifyDataSetChanged()" in the RecyclerViewMaterialAdapter to see if it works the way you want.

Thank you ! I have just solved my problem too, so my problem wasn't about nDSC but I wrong put data to fragments.

Hi all, can you help to post your code? I am facing the problem too. :(

So it should be simple, when you add any data to the adapter, you have to inform the adapter of changes. This is usually done by calling this function on any adapter:

adapter.notifyDataSetChanged();

But since MaterialViewPager wraps the original adapter inside another adapter, you cannot call notify the original adapter. You have to notify the "wrapping" MaterialViewPager adapter.

You can do this by calling the (this is the call you have to make, instead of the above).

wrapperAdapter.mvp_notifyDataSetChanged()

This call does the following:

public void mvp_notifyDataSetChanged()
{
    mAdapter.notifyDataSetChanged();
    notifyDataSetChanged();
}
