Public class RVAdapter extends RecyclerView. I have created a method setFilter, we call this method inside onQueryTextChange method of SearchView.onQueryTextListener interface by passing filtered data list and inside this method make a call to notifyDataSetChanged() api which will do the filtering magic.In our example, here's where you have to set the String values to TextView. onBindViewHolder() : This Method This method is very similar to the getView method of a ListView's adapter.

This is done by inflating the layout using LayoutInflater, passing the output to the constructor of the custom ViewHolder.

onCreateViewHolder() : Inside this method we specify the layout that each item of the RecyclerView should use.

getItemCount() : This method return the number of items present in the data.

RecyclerView.Adapter has three abstract methods that we must override.

Add a constructor to the custom adapter so that it has a handle to the data that the RecyclerView displays, As our data is in the form of a List.

Open adle (Module:app) file and add the following implementation ‘ :recyclerview-v7:26.1. This adapter follows the view holder design pattern, which means that you have to define a custom class that extends RecyclerView.ViewHolder (This pattern minimizes the number of calls to the costly findViewById method.). To use RecyclerView, we need to add recycler view dependency.

Create A Class RVAdapter and this class Must Extend RecyclerView.Adapter.If something else would be useful I'll be happy to add it.
