无法找到此logcat消息中的问题
我似乎无法在此logcat消息中找到崩溃的根源。 我真的希望有人能够帮助它。 如果不是不担心。 以下是我在应用程序崩溃之前得到的消息:(我真的很抱歉这么久）

}
在你的崩溃看看这条线。
co.uk.mednet.mednet_ghana.model.User.getTitle()' on a null object reference
我想你还没有初始化 用户 。
检查您的初始化，或者如果您从服务器接收它，请确保检查用户模型是否为空 。
问题的根源在这里：
尝试在co.uk.mednet.mednet_ghana.fragments.PatientInofrmationFragment.onCreateView（PatientInofrmationFragment.java）的空对象引用上调用虚拟方法'java.lang.String co.uk.mednet.mednet_ghana.model.User.getTitle（）' ：76）at
异常是一个NullPointerException：
java.lang.NullPointerException：尝试在空对象引用上调用虚拟方法'java.lang.String co.uk.mednet.mednet_ghana.model.User.getTitle（）'
您正尝试在空实例上调用.getTitle（）方法。
这里抛出了异常：
co.uk.mednet.mednet_ghana.fragments.PatientInofrmationFragment.onCreateView（PatientInofrmationFragment.java）
在第76行
