在 Android Studio 中膨胀 class android.support.v7.widget.Toolbar 时出错 - Java
Error inflating class android.support.v7.widget.Toolbar in Android Studio - Java
我正在我的应用程序中实施 material 设计。
每当我尝试扩充布局时，应用程序就会崩溃。
我在另一个测试项目中有完全相同的代码，并且工作得很好。
它应该通过 Firebase 检查是否有登录的用户，如果是的话直接进入主菜单。在任何一种情况下，如果用户尝试登录，它都会崩溃。
我看过很多类似的问题，但都是两年前的问题，图书馆也发生了很大变化，没有一个答案适合我的问题。

多亏了这个post我解决了它。
Error inflating class android.support.v7.widget.Toolbar?
问题是当我导入我正在使用的所有可绘制文件时，我不知道为什么 fu** Android Studio 决定在没有警告我的情况下将它们导入 v-24 文件夹.
我将它们移至非 v-24 版本并且它有效。
我正在我的应用程序中实施 material 设计。 每当我尝试扩充布局时，应用程序就会崩溃。 我在另一个测试项目中有完全相同的代码，并且工作得很好。
它应该通过 Firebase 检查是否有登录的用户，如果是的话直接进入主菜单。在任何一种情况下，如果用户尝试登录，它都会崩溃。
我看过很多类似的问题，但都是两年前的问题，图书馆也发生了很大变化，没有一个答案适合我的问题。

我将它们移至非 v-24 版本并且它有效。
