Answer 1

In your RecyclerView adapter class, for example MyRecyclerViewAdapter, make a constructor with the following params.

MyRecyclerViewAdapter(Context context, List data) {
    this.mInflater = LayoutInflater.from(context); // <-- This is the line most people include me miss
    this.mData = data;
}

mData is the data that you'll pass to the adapter. It is optional if you have no data to be passed. mInflater is the LayoutInflater object that you have created and you use in the OnCreateViewHolder function of the adapter.

After this, you attach the adapter in the MainActivity or wherever you want to on the main/UI thread properly like

MyRecyclerViewAdapter recyclerAdapter;
OurDataStuff mData;

    ....
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //Like this:

        RecyclerView recyclerView = findViewById(R.id.recyclerView);
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerAdapter = new RecyclerAdapter(this, mData); //this, is the context. mData is the data you want to pass if you have any
        recyclerView.setAdapter(recyclerAdapter);
    }
   ....
