android - 将 Android Studio 升级到北极狐后膨胀片段时出错

Question

我看到 Jetpack Compose 已经退出测试版，所以我想我会升级到北极狐。Compose 看起来非常高效，我想将它添加到我当前的项目中。

然而，在升级我的项目后，我除了构建错误和崩溃之外什么都没有。据我所知，它在膨胀布局时遇到问题，然后导致lateinit property not initialized error. 由于某种原因，它似乎无法识别<include>我的布局文件中的标签，或者它的<androidx.appcompat.widget.Toolbar>标签。

我在某处阅读以将 AGP 和 Gradle 版本更新到 7，但这并没有改变任何东西。其他项目无需升级即可运行，但有时升级后也会崩溃。在其他出现相同错误的项目中，它总是看起来像它位于工具栏标签的末尾。我没有对我的代码进行任何更改，只对插件版本进行了更改，所以我不知道为什么它会出现以前工作正常的问题。

我完全迷路了。我已经与 SDK 斗争了一周，但没有得到任何结果。

我唯一的选择似乎是恢复到旧的 SDK 或尝试 Bumblebee Canary 7。

activity_main.xml

<androidx.drawerlayout.widget.DrawerLayout
    android:id="@+id/drawer_layout">

    <include
        android:id="@+id/nav_host_layout"
        layout="@layout/nav_host"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:visibility="visible"/> // line 24 in activity_main.xml

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/nav_view" />

</androidx.drawerlayout.widget.DrawerLayout>

导航主机.xml

<LinearLayout>

<include
    layout="@layout/view_main_app_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="visible" />

<include
    layout="@layout/view_search_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="gone" />

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <fragment
        android:id="@+id/nav_host_fragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        app:defaultNavHost="true"
        app:navGraph="@navigation/navigation" /> // line 37 in nav_host.xml
</FrameLayout>

MainActivity.kt

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setTheme(R.style.Theme_MyApp_NoActionBar)
    setContentView(R.layout.activity_main)  // debug show it starts blowing up here
