RecyclerView With Android DataBinding

In I/O 2015 Google announced a data binding library for Android. With Data Binding, you create an ongoing link between an element in the user interface and a value. Data Binding is the process that establishes a connection between the application UI and business logic.

In this post we will learn how to integrate recyclerview with android Data Binding.

Step 1 : Enable dataBinding in your module level gradle, here is how your build.gradle should look like.

Step 2 : Create POJO/Model class called User with 3 parameters name, profile_image & age.

Step 3 : Create a layout for Recycler list items

Here user will be model class reference variable, you can have any number of variables as you need. <layout> will contain your model class information using which you will notify your controls about value they are going to show.

Step 4 : Create an adapter for Recyclerview called UserAdapter

Here
binding = DataBindingUtil.bind(itemView); will create binding for your recycler_item layout and return view.
binding.setUser(user); will set User data to recycler items.

Step 5 : Write xml code for your activity/fragment layout

Step 6 : Write your code in activity/fragment to attach adapter to Recyclerview.

Output :
