activity_login.xml

Question

我正在开发一个Android应用程序，我正在使用Fabric / Crashlytics推送给测试人员。

我自己在2台物理设备上彻底测试了我的应用程序：

Samsung Galaxy Tab Pro运行4.4.2（API 19）
LG G3正在运行5.0.1（API 21）

我最近将一个版本的应用程序推送给了一个测试人员。她的设备是：

三星Galaxy S4运行5.0.1（API 21）

我正在尝试使用登录/注册Activity / Fragment系列。我通过Crashlytics收到崩溃报告，其中包含以下信息：

以下是日志的摘录：

我在这里查看了与InflateException相关的其他几篇帖子，但这些帖子似乎都不适用于我的情况。

例如：

This question and answer似乎突出了包命名问题，这在我的项目中不是问题。
This question and answer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this question以确定我的问题是否可能与使用AppCompatActivity有关，但到目前为止我还没有看到任何有问题的内容。

所以，基本上，让我感到困惑的是我在任何一台设备上都没有这个问题，而且我不太了解Android以便在她的系统上看到任何东西（也是运行5.0.1的三星手机），就像我的那样）会有问题。有什么我想念的吗？如何找出实际问题是什么？

InflateException，因为Fragment没有创建视图

activity_login.xml

LoginActivity.java

fragment_login.xml

fragment_login.xml中的第70行

LoginFragment.java
