Recyclerview generic adapter — Android

<p>RecyclerView is a powerful widget for displaying lists and grids in Android applications. To maximise code reusability and maintainability, it&rsquo;s crucial to build a flexible and generic adapter that can work with various data types effortlessly. In this blog post, we&rsquo;ll explore the implementation of a GenericListAdapter class that simplifies the process of creating RecyclerView adapters for different data models.</p> <h2>Understanding the Code Snippet</h2> <p>The provided code snippet introduces an abstract class called GenericListAdapter. Let&rsquo;s break down its key components and understand how it enables us to create a reusable adapter:</p> <pre> abstract class GenericListAdapter&lt;T&gt;(diffUtil: DiffUtil.ItemCallback&lt;T&gt;) : ListAdapter&lt;T, RecyclerView.ViewHolder&gt;(diffUtil), Filterable</pre> <p>The class is abstract and takes a generic type parameter &lsquo;T,&rsquo; representing the data type that the adapter will work with. It extends the ListAdapter class with the data type &lsquo;T&rsquo; and a DiffUtil.ItemCallback to handle data updates efficiently. Additionally, it implements the Filterable interface, indicating that it supports filtering functionality.</p> <p><a href="https://towardsdev.com/recyclerview-generic-adapter-android-13b86778b404">Visit Now</a></p>
