When the user touches an item in the RecyclerView, you can handle that event by adding a bit of code in one of the component’s methods. RecyclerView supports the most common events you might want to handle, such as click and long-click events. When using the older ListView, you put your event handing code in the activity or fragment that "owns" the list. With RecyclerView, that code goes in the adapter that manages the visual presentation.
- [Instructor] When the user touches an item…in the recycler view, you can handle that event…by adding a bit of code in one of the adapter's methods.…With the list view component,…you add code to handle list view events…in the class that owns the list view…rather than the adapter or the list view itself.…With the recycler view,…you put it into the data item adapter.…First, you need a reference to the view…that represents a single data item.…And the easiest way to get that is to expose that…as a member of the view holder class.…
I'll go to the view holder and I'll add a new public field…and I'll set its type as view and then I'll name it m view.…And then I'll set its reference in the constructor method.…I'm already getting a reference to it named item view…as an argument.…So I'll say m view equals item view.…Now, that view reference will be available…to the rest of the adapter.…Next, I'll go to the method on bind view holder.…This is where you supply the data…that you want to display to the user…and it's also where you set up your event handlers.…
