尝试为我的片段生成绑定类时出错

Question

我有以下 XML 文件，它是我的 Fragment 的布局 -

<?xml version="1.0" encoding="utf-8"?>

<layout>

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/white"
        android:orientation="vertical"
        android:padding="15dp"
        tools:context=".fragments.DashboardFragment">

        <androidx.viewpager2.widget.ViewPager2
            android:id="@+id/fragment_dashboard_viewpager"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </LinearLayout>

</layout>

FragmentDashboardBinding 类确实是自动生成的，但我不能使用它 -

class DashboardFragment : Fragment(R.layout.fragment_dashboard) {

    private lateinit var binding : FragmentDashboardBinding


    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        binding = FragmentDashboardBinding.inflate(inflater, container, false)
        return super.onCreateView(inflater, container, savedInstanceState)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
    }

}

我在尝试构建项目时遇到了我在顶部看到的错误，使其无法使用

我错过了一些东西。会是什么？

我已经按照我应该的方式包装了我的布局文件

我目前只需要视图绑定，不需要数据绑定。

请更改您的fragment 如下：

class DashboardFragment : Fragment() {

    private lateinit var binding : FragmentDashboardBinding

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        binding = DataBindingUtil.inflate(inflater, R.layout.fragment_dashboard, container, false)
        return binding.root
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
    }

}
