错误:在androidX中膨胀类com.google.android.material.navigation.Navig

Question

我的应用程序在API 26级或更高级别以上工作，但在API 26级以下停止工作。请帮帮我…

为什么XML在膨胀类时返回错误，并在较低的API级别停止工作？

我尝试了这些方法，但没有奏效：

如果您使用的是android Studio中的默认导航抽屉模板代码，请检查您的代码中使用的com.google.android.material.navigation.NavigationView中的可绘制资源和颜色资源，可能是在activity_main.xml中。检查可绘制文件是否位于res/drawable文件夹中，而不是res/drawable-v21中。检查您是否在NavigationView中使用了android:backgroundTint((或android:src或类似功能。由于它们在安卓API 21级以下不工作，请改用app:backgroundTint或app:srcCompat。

Answer 1

请确保将Drawerlayout库添加到build.gradle(：app(文件中，以便使用Drawerlayout。如果没有，请打开build.gradle(：app(文件并添加：实现"；androidx.drawerlayout：drawerlayout:1.1.1"；

在AndroidX NavigationView中需要这些依赖项，还可以查看文档以获取更多信息
