Android's RecyclerView example misunderstanding

I'm trying to follow the example here:

https://developer.android.com/training/material/lists-cards.html#RecyclerView

And there's a part which isn't very clear to me.

@Override
    public BlogPostAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                                   int viewType) {
        // create a new view
        View v = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.my_text_view, parent, false);
        ViewHolder vh = new ViewHolder(v);
        return vh;
    }

In this part, they are inflating a layout with "my_text_view". I'm having trouble recreating this layout. If I create a single xml file "my_text_view.xml" with a just a TextView, it won't compile. If I surround my TextView with "LinearLayout" I will fail to cast it to TextView for the example to work. Create just a just a TextView with an ID and trying to inflate it will fail since that method takes a Layout as a parameter not a view.

How could I make this my_text_view layout for this example to work?

It should compile using just a TextView inside the layout file. Just make sure to add the xmlns:

<?xml version="1.0" encoding="utf-8"?>
<Textview xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/text_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

If you would want to wrap it inside a parent layout, when setting the viewHolder, you need to obtain the textview you're interested in from the view you inflate. You can obtain it by calling

view.findViewById(R.id.text_view);
