大家是如何给recyclerview 的item点击时添加选中状态的，这边添加item选中状态会造成卡顿，严重掉帧。

数据源实体Bean继承BaseObservable

定义变量，用liveData
@get:Bindable
var checked = MutableLiveData(false)

data class BeanModel():androidx.databinding.BaseObservable(){
@get:Bindable
var checked = MutableLiveData(false)
}

在改变选中状态的时候直接设置
xx.checked.postValue(true/false)
or
xx.value = true/false
