android - 当我点击注册按钮时，它应该将我重定向到下一页，但这并没有发生

问题描述

所以，基本上当我点击注册按钮时，它应该将我重定向到下一页。我尝试了各种方法，但没有奏效。即使没有错误，当我点击按钮时，它仍然被点击但没有被定向到下一页.我已经粘贴了下面的所有代码。任何帮助将不胜感激。

这是我的 new_user_login.xml 文件。

解决方案

您的问题是registration() 方法只设置onClickListener，它不会调用它。

似乎您没有设置 onclicklistener，即使您设置了第二个（创建 toast）也可能会覆盖它。

因此，要么调用registration（）而不是另一个，要么调用另一个onClickListener内部的注册，没有onClick的东西（因为代码应该被执行，如果你在监听器内部则不需要onClick）
