我的应用程序正在使用新的 AndroidX 框架，并且在设置com.google.android.material.navigation.NavigationView（在我的 activity_main.xml 文件中）时，出现此错误：

谢谢你帮我解决这个问题！

PS：我已经查看了可能的重复问题，而答案涉及android.support图书馆。但是，由于我没有在我的代码中使用支持或设计库，因此该解决方案不适用于我。的android.support版本NavigationView和安卓素材版本NavigationView不同。

我也尝试使用此链接来提供帮助，但找不到答案：https ://material.io/develop/android/components/navigation-view/

尝试删除 nav_header_main.xml 文件中的所有大图像（背景、图标、...）！

改变你的风格如下

<style name="AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

将您的清单更改为

 <application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name_real"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"
    tools:ignore="GoogleAppIndexingWarning">
    <activity android:name=".SignIn" android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:theme="@style/AppTheme.NoActionBar"
        android:name=".MainActivity"
        android:label="@string/title_activity_main"/>
</application>
