Integrating the Navigation Component with other Android components is essential for developing a seamless user experience. The Navigation Component simplifies the implementation of navigation within an app and works well with various Android components such as Fragments, Activities, and ViewModels.
Here’s a simple example of how to integrate the Navigation component with a Fragment and a ViewModel:
// In your build.gradle file, make sure to include necessary dependencies
implementation "androidx.navigation:navigation-fragment-ktx:2.3.5"
implementation "androidx.navigation:navigation-ui-ktx:2.3.5"
// Sample Fragment Code
class MyFragment : Fragment() {
private lateinit var viewModel: MyViewModel
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
viewModel = ViewModelProvider(this).get(MyViewModel::class.java)
return inflater.inflate(R.layout.fragment_my, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
// Set up Navigation
val navController = findNavController()
val navHostFragment = navController.getCurrentDestination()
}
}
// ViewModel Code
class MyViewModel(application: Application) : AndroidViewModel(application) {
// ViewModel logic goes here
}
