5.1 ListView vs. RecyclerView
RecyclerVieware two different layouts that can be used to display a list of objects, but it is often difficult to tell which one is being used in a mobile app.
Typically the implementation of a
ListViewis simpler than a
RecyclerViewbut are less performant. For apps like those you built in HW4 and will build in HW5 where there are minimal calculations, a
ListViewis perfectly serviceable.
We used both types of layouts in Eatery:
Looking at a list in an app for the first time, it’s difficult to tell whether the screen is made with a list view or a recycler view. In fact, to the user, there is almost no visual difference between a list made with either layouts.
The main difference between the two layouts stems from how they handle performance. In the industry, it is highly recommended to use a recycler view unless you are building a very simple list that does not require heavy computations, as previously mentioned.
