I am able to open my BottomSheetDialogFragment with
val bottomSheet = BottomSheetFragment()
bottomSheet.show(fragmentManager!!, "BottomSheet")
but it only opens to show half of its content - I would like it to expand on opening to the full height of the screen without having to drag it up.
I have looked around and it seems one way is to set the BottomSheetBehavior state to STATE_EXPANDED, but I have not been able to find a solution on how to do this in Kotlin.
Any help would be appreciated!
You can set the BottomSheetBehavior state by placing this inside
onViewCreated of your BottomSheetDialogFragment.
dialog.setOnShowListener { dialog ->
val d = dialog as BottomSheetDialog
val bottomSheet = d.findViewById<View>(R.id.design_bottom_sheet) as FrameLayout
val bottomSheetBehavior = BottomSheetBehavior.from(bottomSheet)
bottomSheetBehavior.state = BottomSheetBehavior.STATE_EXPANDED
}
You may also want to set the peek height to the height of your dialog to prevent the dialog getting stuck half way when attempting to dismiss it.
bottomSheetBehavior.peekHeight = bottomSheet.height
