What is a navigation component?
- Simplifying navigation code: The navigation component uses a declarative approach to define navigation paths in your app, reducing the need for boilerplate code and making it easier to manage navigation.
- Handling common scenarios: The navigation component provides built-in support for common navigation scenarios, such as handling the back button, passing data between destinations, and handling deep linking.
- Providing a visual editor: Android Studio includes a visual editor for the navigation component, which makes it easy to create and modify navigation graphs.
To use the navigation component in your app, you need to follow these steps:
- Add the navigation component to your project by including the following dependency in your app-level build.gradle file:
implementation "androidx.navigation:navigation-fragment-ktx:$version_navigation"
- Create a navigation graph by defining the destinations and navigation paths in an XML file. You can use the visual editor in Android Studio to create the graph or write the XML code manually.
- Define the navigation actions in your code by calling the NavController object to navigate between destinations. You can also use the NavigationUI class to set up common navigation patterns, such as the navigation drawer or bottom navigation.
- Connect your destinations to the navigation graph by adding a NavHostFragment to your layout and setting it up in your code.
By following these steps, you can use the navigation component to handle navigation in your Android app, providing a simple and consistent experience for your users.
