First, open your app/build.gradle file
Inside the android{} block of app/build.gradle, add the following:
buildFeatures { viewBinding = true }
Sync project with gradle files.
In your activity or fragment, define the following class-wide property:
private lateinit var binding: FragmentorActivityNameBinding
Replace the FragmentorActivityNameBinding above with the appropriate binding class name. Tip: The binding class name is based on the XML file’s name. For example, if your XML file name is activity_main.xml, the binding class name should be ActivityMainBinding. Or, if your file name is fragment_main.xml, the binding class name should be FragmentMainBinding.
In your activity, the onCreate function should look like this:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMainBinding.inflate(layoutInflater)
val view = binding.root
setContentView(view)
}
Otherwise, if using view binding in a fragment, your onCreateView should look like this:
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View {
binding = FragmentMainBinding.inflate(inflater, container, false)
binding.lifecycleOwner = viewLifecycleOwner
binding.viewModel = mainViewModel
return binding.root
}
