android - 为什么BottomSheetBehavior抛出java.lang.IllegalArgumentException : Illegal state argument: 2 when I'm trying to set state to STATE_SETTLING

Question

我有一种方法可以对 map 单击采取措施，当我单击 map 时，该方法试图将状态设置为STATE_SETTLING，但它会抛出IllegalArgumentException
我已经检查了它是否不在STATE_HIDDEN或STATE_SETTLING中的状态，并且isHideable是true，但是它正在抛出java.lang.IllegalArgumentException: Illegal state argument: 2
。我试图将状态设置为STATE_EXPANDED，STATE_HALF_EXPENDED，这些状态运行良好，但不是我想要的。

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
    }

    }
}

问题解决了，我需要稍微更改一下代码，而我尝试将状态设置为STATE_SETTLING时会抛出IllegalArgumentException，我只是将代码更改为zonesViewModel.merchantInfoBottomLayout!!.state = BottomSheetBehavior.STATE_COLLAPSED而不是zonesViewModel.merchantInfoBottomLayout!!.state = BottomSheetBehavior.STATE_SETTLING
