Android 布局未加载

Question

Android 布局过去在我的旧电脑上加载得很好，但是当我试图在我的新笔记本电脑上从 GitHub 运行我的项目时，应用程序运行在模拟器中完全没问题。但是，我的一些布局显示空白屏幕，如下所示：

xml代码：

<?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_main"
        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:itemIconTint="@color/teal_700"
        app:headerLayout="@layout/nav_header_main"
        app:menu="@menu/activity_main_drawer" />
</androidx.drawerlayout.widget.DrawerLayout>

Google Material 版本：com.google.android.material:material:1.2.1

布局错误：

我尝试在互联网上搜索这些错误，但找不到与我的问题相关的任何答案。

奇怪的是，它加载了一些布局，但不是所有布局

我再次尝试构建项目，但没有成功。

添加新的 xml 布局文件工作正常，但原始文件存在问题。代码没有错误，应用运行没问题。

希望有人能够找出这里的问题。提前致谢

问题已解决。这是 android:autofillHints=""

的问题

Answer 1

首先做文件->与gradle个文件同步，如果此后问题仍未解决，则执行文件 -> 使缓存无效并重新启动

Answer 2

找遍全网，终于找到了问题所在。感谢

因为 android:autofillHints="" 没有在我以前的 android 工作室版本中留下错误。但现在它确实如此，希望这对将来的人有所帮助。

Answer 3

构建 >> 清理项目

在 Gradle 调用完成后...

构建 >> 重建项目
