How can I change default black dim background “color” (not the amount of dim) of Dialog?

Answer 1

This worked for me:

val dialog = AlertDialog.Builder(context)
                .setView(view)
                .setCancelable(true)
                .setPositiveButton(R.string.done_label, { dialog, _ -> dialog.dismiss() })
                .create()
        dialog.window.setDimAmount(0f)
        dialog.show()

dialog.window.setDimAmount(0f) is the key.
