How to use BottomSheetDialog?

Question

I want to try BottomSheetDialog introduced in Android Support Library 23.2 but it doesn\'t seem to work correctly. Here is what the doc says:

Answer 1

Instead of having a separate class, you can simply create an instance for BottomSheetDialog in your Activity/Fragment like following and you can use it. It is very easier and simpler I think.

val dialog = BottomSheetDialog(this)
val bottomSheet = layoutInflater.inflate(R.layout.bottom_sheet, null)

bottomSheet.buttonSubmit.setOnClickListener { dialog.dismiss() }

dialog.setContentView(bottomSheet)
dialog.show()
