Saripaar 验证库引发"找不到规则"错误

Question

我正在尝试在我的项目中使用 Saripaar 验证，但它抛出以下错误：

java.lang.IllegalStateException：未找到规则。您必须在 至少要验证一个规则。如果您使用的是自定义批注，请使 确保您已使用"Validator.register()"注册它们 方法。

我的体系结构将处理视图的责任分离到一个类中，例如对于 LoginActivity，我有 LoginView，这是我处理视图逻辑(如 ButterKnife 注入、事件侦听等)的地方。在本课程中，我有我的注释字段。我的登录视图如下所示：

public void setContext(LoginActivity context) {

}
}

根据我的猜测，图书馆正在尝试在我的活动中查找这些字段，并且由于它们不存在，因此它会抛出此错误。

有没有办法根据我正在处理的架构使用此库？

Answer 1

使用validator = new Validator(this)代替validator = new Validator(context);
