Android kotlin: Material button rounded corners example

This class supplies updated Material button rounded corners example styles for the button in the constructor. The widget will display the correct default Material styles without the use of the style flag.
All attributes from MaterialButton are supported. Do not use the android:background attribute. MaterialButton manages its own background drawable, and setting a new background means Material button change color example can no longer guarantee that the new attributes it introduces will function properly. If the default background is changed, Material Button cannot guarantee well-defined behavior.
At MainActivity.kt

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val context = this
        button2.setOnClickListener {
            button2.cornerRadius = 16.toDp(context)
        }
    }
}
fun Int.toDp(context: Context):Int = TypedValue.applyDimension(
    TypedValue.COMPLEX_UNIT_DIP,this.toFloat(),context.resources.displayMetrics
).toInt()
