What is ViewBinding in Android SDK?

ViewBinding is a feature in the Android SDK that allows developers to more easily interact with views in their layouts. It generates a binding class for each XML layout file, enabling type-safe access to views, reducing boilerplate code, and improving performance. Particularly useful for handling views in the UI, ViewBinding eliminates the need for calls to findViewById, and it provides compile-time safety, ensuring that views exist at the time of binding.

How to Enable ViewBinding

To enable ViewBinding in your Android project, follow these steps:

  1. Open your `build.gradle` (Module) file.
  2. Add the following code inside the `android` block:
android { ... viewBinding { enabled = true } }

Using ViewBinding

Here is an example of how to use ViewBinding in an Activity:

// In your activity class class MainActivity : AppCompatActivity() { private lateinit var binding: ActivityMainBinding override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) binding = ActivityMainBinding.inflate(layoutInflater) setContentView(binding.root) binding.textView.text = "Hello ViewBinding!" } }
