|
+1- The RecyclerView object: The overall container for your user interface is a RecylerView object that you add to your layout(You can add this object to your layout after adding its dependency to your build.gradle file).
|
|
|
+
|
|
|
+2- Layout manager: The RecyclerView fills itself with views provided by a layout manager. There are 3 different types of layout managers that can be used:
|
|
|
+
|
|
|
+ LinearLayoutManager which lays out items vertically or horizontally
|
|
|
+ GridLayoutManager that lays out items in a grid
|
|
|
+ StaggeredGridLayoutManager which lays out items in a staggered grid formation
|
|
|
+
|
|
|
+Also, we can implement our own layout manager
|
|
|
+
|
|
|
+3- ViewHolder: The views in the list are represented by the view holder. Each view holder is in charge of displaying a single item with a view. We create a view holder object by extending our class from ReclerView.ViewHolder.
|
|
|
+
|
|
|
+4- Adapter: An adapter manages the ViewHolder objects. It creates not only ViewHolders as needed, but also binds the ViewHolders with their data. We create an adapter by extending our class from RecyclerView.Adapter.
|
|
|
+
|
|
|
+5- List of datasets: A list of datasets that we want to show in our RecyclerView. In this tutorial, we use a list of Strings.
