Java 找到属性uid的两个区分大小写冲突的getter或字段

我试图通过用户名搜索用户，我添加了搜索栏、列表视图、适配器等等，但我遇到的问题是，当我在搜索字段“Find two Getter or fields with conflicting case sensitivity for property:uid”中输入用户名时，出现了这个错误，我不知道如何解决它。 这是我的日志

这可能是由于

Users.java

中的字段和方法大写所致。尝试修复它。你能发布你的“Users.java”吗？似乎有两个getter或两个字段具有相同的名称，但大小写不同（正如@josepraveen所提到的）。还要记住，java类通常不是多重的。其罚款有一个集合用户；但是你不想有像Users=newusers（）这样的东西；您的名字应该遵循Java代码标准（例如，您会注意到代码片段中的突出显示是不正确的，因为您没有遵循标准）；特别是，类以大写开头，成员（字段/方法）以小写开头。Sun定义了基本标准，但现在几乎所有样式都是上的次要变体。我添加了Users.java。谢谢，我解决了这个问题@Josepraven:）这可能是由于
