的情况下：

1. 包含通用布局（不是合并节点），我们需要为包含的部分分配 ID，这样在绑定中我们将可以访问包含的子部分

这种方式在您的活动代码中：

private lateinit var exampleBinding: ActivityExampleBinding  //activity_example.xml layout

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    exampleBinding = ActivityExampleBinding.inflate(layoutInflater)
    setContentView(exampleBinding.root)
    //we will be able to access included layouts view like this
    val includedView: View = exampleBinding.yourId.idOfIncludedView
//[...]
}

1. 在外部布局中包含合并块。我们无法为其添加 ID，因为合并块不是视图。假设我们有这样的永恒合并布局（merge_layout.xm）：

   <?xml version=”1.0” encoding=”utf-8”?>
   xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" tools:showIn="@layout/activity_example">

   <TextView
       android:id="@+id/some_view"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="Hello World" />
   

要正确绑定这样的合并布局，我们需要：

在您的活动代码中：

private lateinit var exampleBinding: ActivityExampleBinding  //activity_example.xml layout
private lateinit var mergeBinding: MergeLayoutBinding  //merge_layout.xml layout

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    exampleBinding = ActivityExampleBinding.inflate(layoutInflater)
    //we need to bind the root layout with our binder for external layout
    mergeBinding = MergeLayoutBinding.bind(exampleBinding.root)
    setContentView(exampleBinding.root)
    //we will be able to access included in merge layout views like this
    val mergedView: View = mergeBinding.someView
//[...]
}
