MVVM and Android
Explore the MVVM architecture in Android development. Understand how Models, ViewModels, and Views interact using LiveData and Room to build maintainable, loosely coupled applications. Gain insight into data management, lifecycle awareness, and separation of concerns within Android projects.
Introduction to MVVM in Android
We’ll be going through the same illustration again, but this time, we’ll learn how all this is integrated into Android through actual code.
We’ll accomplish this by looking at some code snippets from the MVVM structure, which are intended to give us a general understanding of what we mean when we say we’re developing loosely coupled code. We’ll limit our attention to the primary classes connected with this architecture.
Model
The model class is simply a data source from which our data is gathered and supplied to the ViewModel, which then provides it to the View, which is either a Fragment or an Activity.
The model is composed of the following components:
The data model/data class
The data model (or class) is a class that’s only used to ...
