kotlin in how to set without findviewbyid
To set up a view in Kotlin without using findViewById
, you can leverage Kotlin Android Extensions or View Binding. Here are the steps to achieve this:
Step 1: Enable Kotlin Android Extensions or View Binding in your project's build.gradle file.
For Kotlin Android Extensions:
android {
...
androidExtensions {
experimental = true
}
}
For View Binding:
android {
...
viewBinding {
enabled = true
}
}
Step 2: Import the necessary class for accessing views.
For Kotlin Android Extensions:
import kotlinx.android.synthetic.main.activity_main.*
For View Binding:
import com.example.app.databinding.ActivityMainBinding
Step 3: Access the view directly by its ID.
For Kotlin Android Extensions:
textView.text = "Hello, Kotlin!"
For View Binding:
val binding = ActivityMainBinding.inflate(layoutInflater)
binding.textView.text = "Hello, Kotlin!"
That's it! By following these steps, you can set up views without using findViewById
in Kotlin. This approach simplifies your code and makes it more concise and readable.
