如何在Kotlin中查看绑定多个布局

android {
    ...
    viewBinding {
        enabled = true
    }
}

<!-- layout_one.xml -->
<LinearLayout ...>
    ...
</LinearLayout>

<!-- layout_two.xml -->
<RelativeLayout ...>
    ...
</RelativeLayout>

// 在 Activity 中
private lateinit var bindingOne: LayoutOneBinding
private lateinit var bindingTwo: LayoutTwoBinding

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    bindingOne = LayoutOneBinding.inflate(layoutInflater)
    bindingTwo = LayoutTwoBinding.inflate(layoutInflater)
    
    setContentView(bindingOne.root) // 设置第一个布局为当前布局
    
    // 访问第一个布局中的视图
    val textViewOne = bindingOne.textView
    val buttonOne = bindingOne.button
    
    // 切换到第二个布局
    setContentView(bindingTwo.root)
    
    // 访问第二个布局中的视图
    val textViewTwo = bindingTwo.textView
    val buttonTwo = bindingTwo.button
}

// 在 Fragment 中
private var _bindingOne: LayoutOneBinding? = null
private var _bindingTwo: LayoutTwoBinding? = null
private val bindingOne get() = _bindingOne!!
private val bindingTwo get() = _bindingTwo!!

override fun onCreateView(
    inflater: LayoutInflater,
    container: ViewGroup?,
    savedInstanceState: Bundle?
): View {
    _bindingOne = LayoutOneBinding.inflate(inflater, container, false)
    _bindingTwo = LayoutTwoBinding.inflate(inflater, container, false)
    
    val rootView = bindingOne.root // 设置第一个布局为当前布局
    
    // 访问第一个布局中的视图
    val textViewOne = bindingOne.textView
    val buttonOne = bindingOne.button
    
    // 切换到第二个布局
    _bindingTwo?.let { binding ->
        _bindingOne = null // 释放第一个布局的绑定
        rootView = binding.root
    }
    
    // 访问第二个布局中的视图
    val textViewTwo = bindingTwo.textView
    val buttonTwo = bindingTwo.button
    
    return rootView
}

override fun onDestroyView() {
    super.onDestroyView()
    _bindingOne = null
    _bindingTwo = null
}
