An analysis of Android Recyclerview.

The appearance of Recyclerview can replace the ListView. The use of Recyclerview is very flexible, the division of labor is more explicit, adapter is used to show the view of item, Viewholder keeps each item and handles the interaction.

Below is the layout of item.

Here is the oncreate in activity,

Then the main is the processing in adapter.

In Oncreateviewholder, the main object is to create Viewholder objects, and to pass view views to Viewholder,onbindviewholder is to display the data in the item's view, among other things.

In Viewholder, events are passed through an interface to the activity to handle. Such a clear division of labor, eliminating the ListView in the Convertview.settag and Gettag operations.
