【问题描述】：

Android 布局过去可以在我的旧计算机上正常加载，但是当我尝试在我的新笔记本电脑上从 GitHub 运行我的项目时，该应用程序在模拟器中运行得非常好。但是，我的一些布局显示像这样的空白屏幕：

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>

谷歌资料版本：com.google.android.material:material:1.2.1

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，它在某些布局中加载，但不是全部

我尝试再次构建项目，但没有成功。

添加新的 xml 布局文件可以正常工作，但原来的有问题。 代码没有错误，应用运行正常。

希望有人能够在这里找出问题所在。提前致谢

问题解决了。 这是android:autofillHints="" 的问题

【问题讨论】：

    标签： android xml android-studio android-layout


    【解决方案1】：

    首先做文件-> 与 gradle 文件同步， 如果之后问题仍未解决，请执行 文件 -> 使缓存无效并重新启动

    【讨论】：

      【解决方案2】：

      搜索了整个互联网后，我终于找到了问题所在。 感谢https://stackoverflow.com/a/66717456/14030881

      android:autofillHints="" 在我以前的 android studio 版本中没有留下错误。 但现在确实如此，希望这对将来的人有所帮助。

      【讨论】：

        【解决方案3】：

        构建 >> 清洁项目

        Gradle 调用完成后...

        构建 >> 重建项目
