导航抽屉在 android 棒棒糖中不工作
Navigation drawer not working in android lollipop
我在我的项目 Android 设计库中使用了导航视图，但我遇到了问题。从 API 15 到 20 一切正常，就像假设的那样，但是当我尝试 API 21 (5.0) 及更高版本时，即使没有显示汉堡包按钮，它也无法正常工作。而且我找不到问题出在哪里。有没有人遇到过类似的问题？我正在使用 C# 在 xamarin 中工作。这是代码：

如果有人将来遇到类似问题，这就是我的问题的解决方案。正如我猜测的那样，问题不在代码中。我通过组件添加了设计库，但这不是最新版本，您将在 android lollipop 或更高版本中遇到错误，因此通过 NuGet 包添加它或进行更新，您将获得最新版本。
我在我的项目 Android 设计库中使用了导航视图，但我遇到了问题。从 API 15 到 20 一切正常，就像假设的那样，但是当我尝试 API 21 (5.0) 及更高版本时，即使没有显示汉堡包按钮，它也无法正常工作。而且我找不到问题出在哪里。有没有人遇到过类似的问题？我正在使用 C# 在 xamarin 中工作。这是代码：

如果有人将来遇到类似问题，这就是我的问题的解决方案。正如我猜测的那样，问题不在代码中。我通过组件添加了设计库，但这不是最新版本，您将在 android lollipop 或更高版本中遇到错误，因此通过 NuGet 包添加它或进行更新，您将获得最新版本。
