二進制 XML 文件第 24 行：錯誤膨脹類 com.google.android.material.navigation.NavigationView

我正在嘗試運行我的應用程序，但它不斷輸出此消息：

此錯誤似乎是由於我用於主要活動的布局中的 NavigationView 膨脹錯誤而發生的，但我找不到原因。 我所有的屬性和可繪制對象都正確鍵入並且可用。 僅供參考，我使用 homepage.xml 作為我的活動布局和 main_menu.xml 作為我的導航布局。

提前致謝。

編輯：發現錯誤

我使用的屬性 ?attr/textColor 旨在用於設置單獨的明暗模式字體，但從錯誤中可以看出，這並沒有真正起作用。 不過，設置 android:textColor 屬性效果很好。

確保在你的: build.gradle(Module: app) 中添加這些依賴項

implementation 'androidx.navigation:navigation-fragment:2.0.0'
implementation 'androidx.navigation:navigation-ui:2.0.0'
