Android 因片段未创建视图而引发的充气异常

我正在开发一个Android应用程序，我正在使用Fabric/Crashlytics向测试人员推出它

我自己已经在2台物理设备上彻底测试了我的应用程序：

三星Galaxy Tab Pro运行4.4.2（API 19）

LG G3运行5.0.1（API 21）

我最近向一个测试人员推出了我的应用程序的一个版本。她的设备是：

• 运行5.0.1（API 21）的三星Galaxy S4

我有一个登录/注册

活动

/

片段

系列，她正在尝试使用。我通过Crashlytics获得一份崩溃报告，其中包含以下信息：

以下是日志的摘录：

以下是我的LoginActivity和LoginFragment文件的压缩版本：

activity_login.xml fragment_login.xml 我已经看过这里的其他几篇与

InflateException

相关的文章，但它们似乎都不适用于我的情况

例如：

似乎突出了包命名的问题，这在我的项目中不是问题

正在处理代码行顺序不正确的问题，这在我的项目中不是问题

我查看了一下，试图确定我的问题是否与使用

AppCompatActivity

有关，但到目前为止，我还没有发现任何问题

---

所以，基本上，让我困惑的是，我的两台设备上都没有这个问题，而且我对安卓也不太了解，以至于在她的系统（也是运行5.0.1的三星手机，像我的一样）上看不到任何有问题的东西。有什么我遗漏的吗？如何追踪实际问题？

LoginFragment没有创建视图

请提供在片段中充气和设置视图的代码您是否使用与您正在设置的视图大小相比大小较大的图像文件，如果是，请尝试调整这些图像的大小…@DavidMedenjak添加了它。在片段xml的第70行是什么？@JawadLeWywadi我将在我的问题中添加这些信息。请参见编辑。
