modelView中有两个函数，它们都在影响textview.如何在MVVM中只运行一个

Question

private fun renderA(state :AViewModel.State?){
        when (state){
            is AViewModel.State.Success -> {
                if (state.description.isNotEmpty()) binding.textView1.text = state.description
            }
            else ->{
            }
        }
    }
private fun renderB(state :BViewModel.State?){
        when (state){
            is BViewModel.State.Success -> {
                if (state.description.isNotEmpty()) binding.textView1.text = state.description
            }
            else ->{
            }
        }
    }

这两个功能都在影响textView1
如何阻止它们互相覆盖
它们都来自不同的模型视图和观察者
如何优先考虑renderA：
如果发生renderA，则renderB文本视图部分不应在Clean Code架构中执行？

    private fun renderA(state :AViewModel.State?){
        when (state){
            is AViewModel.State.Success -> {
               setDescription(state.description)
            }
            else ->{
            }
        }
    }
    private fun renderB(state :BViewModel.State?){
        when (state){
            is BViewModel.State.Success -> {
                setDescription(state.description)
            }
            else ->{
            }
        }
    }
fun setDescription(description: String) {
   if(description.isNotEmpty() && binding.textView1.text.isEmpty()){
          binding.textView1.text = description
   }
}
