视图绑定无权访问片段 [英] View binding does not have access to fragment

问题描述

我有一个带有 ConstraintLayout 和片段的活动:

I have an activity with ConstraintLayout and fragment on it:

<androidx.constraintlayout.widget.ConstraintLayout 
 ...attributes....
>
  <fragment
     android:id="@+id/containerView"
     app:navGraph="@navigation/some_navigation"
     ...other attributes...
   />

  ...other views...

我在活动代码中使用视图绑定:

I'm using view binding in the activity code:

  binding = ActivityMainBinding.inflate(layoutInflater)

这里的问题是我无法访问 binding.containerView.在 fragment 的情况下，我应该使用 findViewById 吗?

the issue here that i have no access to the binding.containerView. Does in case of fragment I should use findViewById ?

推荐答案

Fragment tag ( ) is not a view 它充当 容器用于其他视图，因此您无法像其他视图一样访问它...

Fragment tag ( <fragment>) is not a view it act as a container for other views, So you cannot access it like other views...

当您尝试使用 binding

相反，您可以使用，

supportFragmentManager.findFragmentById(R.id.containerView)
