Why BottomSheetBehavior throws java.lang.IllegalArgumentException: Illegal state argument: 2 when I'm trying to set state to STATE_SETTLING

I have a method which take action against map click, when i click on map, method trying to set the state to STATE_SETTLING but it's throwing IllegalArgumentException

I have checked the state if it's not in STATE_HIDDEN or STATE_SETTLING & isHideable is true, but it's throwing java.lang.IllegalArgumentException: Illegal state argument: 2 . I have tried to set the state to STATE_EXPANDED, STATE_HALF_EXPENDED, those state are working well, but not that i want.

fun onMapClickListener(zonesViewModel: ZonesViewModel){
    if(zonesViewModel.merchantInfoBottomLayout!!.state != BottomSheetBehavior.STATE_HIDDEN || zonesViewModel.merchantInfoBottomLayout!!.state != BottomSheetBehavior.STATE_SETTLING){
        zonesViewModel.merchantInfoBottomLayout!!.isHideable = true
        zonesViewModel.merchantInfoBottomLayout!!.state = BottomSheetBehavior.STATE_SETTLING
    }

    }
}

Solution

  • Problem is solved, I needed to change my code a little bit, while I was trying to set state to STATE_SETTLING it's throwing IllegalArgumentException, I've just changed my code to:

    zonesViewModel.merchantInfoBottomLayout!!.state = BottomSheetBehavior.STATE_COLLAPSED

    instead of

    zonesViewModel.merchantInfoBottomLayout!!.state = BottomSheetBehavior.STATE_SETTLING`
