Create a Stub Custom Adapter

First, let us create a stub implementation of a RestaurantAdapter that will be where we put our logic for creating our own custom rows. That can look like this, implemented as an inner class of LunchList:
class RestaurantAdapter extends ArrayAdapter<Restaurant> {
RestaurantAdapter() {
super(LunchList.this,
android.R.layout.simple_list_item_1,
model);
}
}
We hard-wire in the android.R.layout.simple_list_item_1 layout for now, and we get our Activity and model from LunchList itself.
We also need to change our adapter data member to be a RestaurantAdapter, both where it is declared and where it is instantiated in onCreate(). Make these changes, then rebuild and reinstall the application and confirm it.
