android.view.InflateException：二进制XML文件第10行：错误膨胀了类android.support.v7.widget.Toolbar

Question

我正在尝试设置警报管理器应用程序，但是每当我运行我的应用程序时，都会弹出一个运行时异常，告诉我工具栏不能膨胀，我似乎也无法弄清楚原因。

我注释掉了xml中工具栏的代码以及mainactivity，以尝试调试该应用程序。但对于浮动操作按钮，我也会在布局中看到相同的错误，这向我表明问题不是工具栏，而是其他问题。

这是logcat：

Answer 1

支持status:

可能是个问题

请将您的媒体库降级为v7:28.0.0，然后查看问题是否仍然存在

例如：

27.1.0

您还需要更改编译版本并将构建工具也更改为27。

implementation 'com.android.support:appcompat-v7:27.1.0' // appcompat library
implementation 'com.android.support:design:27.1.0'
implementation 'com.android.support:recyclerview-v7:27.1.0'

同步后，重建并清理您的项目
