Java-如何在其他活动中登录Google之后保存Google个人资料

概述我是Android编程新手.我成功集成了Google登录并成功将数据传递给另一个活动.但是,当我通过导航抽屉返回活动时,我在其中传递了数据,因此播出了空白屏幕.我想在该活动中保存用户个人资料.我想通过永久单击应用程序中的“保存”按钮以显示为用户个人资料来保存用户详细信息.请帮助我

我是Android编程新手.我成功集成了Google登录并成功将数据传递给另一个活动.但是,当我通过导航抽屉返回活动时,我在其中传递了数据,因此播出了空白屏幕.我想在该活动中保存用户个人资料.我想通过永久单击应用程序中的“保存”按钮以显示为用户个人资料来保存用户详细信息.请帮助我解决这个问题.谢谢,提前提供解决方案.

这是我的Java文件和XML文件.
