To implement heterogeneous layouts inside the RecyclerView, most of the work is done within the RecyclerView.Adapter. Note: Refer Implementing a Heterogeneous ListView guide on how to inflate multiple item types within a ListView. This guide will explain how to inflate multiple view types inside your RecyclerView widget based on the item type. RecyclerView can also be used to inflate multiple view types in situations where your list might be heterogeneous, in the sense, based on the response from the server, there might be a requirement for inflating different types of layouts (example: Consider facebook home feed where there are a variety of stories such as a status update, location update, single image, image album, video, etc). We will be building on top of the classes from the above guide so it is very important that you have the basic RecyclerView up and running. The UI from the above code is something like below.Make sure you are familiar with RecyclerView by going through the following guide for basic usage of a RecyclerView. We have to add the following dependency in our app > adle file before we can use RecyclerView. But beware this is a really simple and basic RecyclerView implementation.Īlso Read : Learn EventBus, The LocalBroadcastManager Alternative TECHENUM Adding recyclerview dependency
Let us look at how to implement these things one by one. Finally, we will need our item as a POJO or any form you like.Then, we will define an Interface to add update and remove item values.RecyclerView.Adapter requires a RecyclerView.ViewHolder to isolate each row and better mange them.Then, we will need to create a RecyclerView.Adapter implementation.First, we must create a RecyclerView instance in the XML layout.Let us first see what we will be needing to make RecyclerView display items in list. Let us first see what are the steps that we must go through in order to implement RecyclerView. RecyclerView will show only the items which the user is currently looking at.Īlso it is worth noting RecyclerView is really much more straight froward once you grasp the basic idea behind it.
No matter the amount of items you have in your Adapter. It is because RecyclerView does a much better memory management out of the box. If you have just started out with Android Development, this might be a general question on your mind. Why use RecyclerView in the first place ? Why use RecyclerView in the first place ?.
