Best Approach To Communicate Between Fragment/activity And Recyclerview.adapter?

My fragment: public class FragmentSort extends Fragment { @BindView(R.id.sortRecyclerView) RecyclerView sortRecyclerView; protected RecyclerView.Adapter adapter; @Nullabl

Solution 1:

An alternative would be to create a listener interface like this:

publicinterfaceOnStoreItemClickListener {

    publicvoidonStoreItemClicked(Store item);    

}

Then, in your Adapter, you declare a field of type OnStoreItemClickListener and you create a setter method for it.

When you detect a click, you simply check if your listener is set and call the onStoreItemClicked() method.

You can register a listener via the setter from wherever you need.
