防止 BottomSheetDialogFragment 隐藏键盘

Question

If I have keyboard opened in current activity/fragment, when I present the BottomSheetDialogFragment, keyboard gets dismissed, but I want the keyboard to stay up in the background behind the BottomSheetDialogFragment. Is there a way to keep keyboard opened behind bottomSheetDialogFragment when I show the BottomSheetDialogFragment and prevent keyboard from being dismissed?

I am showing the BottomSheetDialogFragment like this:

modalBottomSheet.show(
                (activity as AppCompatActivity).supportFragmentManager,
                ModalBottomSheet.TAG + System.currentTimeMillis().toString()
)

I figured it out. In your BottomSheetDialogFragment's subclass, in the method: override fun setupDialog(dialog: Dialog, style: Int), do:

dialog.window?.setFlags(
            WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
            WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
