Question

我在Android Studio 3.4中预览生成的导航抽屉布局时遇到问题。

这是activity_home.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout 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"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_home"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:headerLayout="@layout/nav_header_home"
        app:menu="@menu/activity_home_drawer" />

</androidx.drawerlayout.widget.DrawerLayout>

我已经尝试了其他建议，但是没有一个与我遇到的问题相匹配。

我试图重新加载预览，清理，重建项目，但到目前为止，这些操作均无效。

我现在完全被困住了。

我遇到了类似的问题，并将Studio更新到3.4.2可以解决此问题。

Answer 2

您是否尝试过文件→“使缓存无效/重新启动”？

请注意，可能需要一段时间才能重新启动。
