Java Android应用程序登录和登录问题
我正在开发一个android应用程序，其中有一个sigin和注册选项。当新用户第一次进入应用程序时，他需要注册。。当他按下sigin选项时，他被引导到帐户创建页面。在那里他需要输入用户名、密码和手机号码。所有这三个值都存储在sqlite（应用程序内存）中，并创建一个密码并发送到用户提供的手机号码。下一个页面是注册页面，用户的用户名和密码和他收到的密码一起被检查。我做这个过程是为了验证手机号码。因此，我的问题是，一旦用户创建了帐户，返回登录选项并输入用户名和密码。。他正在引导到应用程序的第一页。。。因为当帐户创建过程完成时，他的详细信息会保存在应用程序数据库中以供验证。所以用户不需要验证密码。。那么，有没有办法只在注册过程之后才能查看登录按钮呢。。或者类似的事情。。。我在这里发布了siginactivity、signupactivity和register活动。。请检查，如果发现任何错误，请帮助我 注册活动Java Android应用程序登录和登录问题,java,android,sqlite,login,Java,Android,Sqlite,Login,我正在开发一个android应用程序，其中有一个sigin和注册选项。当新用户第一次进入应用程序时，他需要注册。。当他按下sigin选项时，他被引导到帐户创建页面。在那里他需要输入用户名、密码和手机号码。所有这三个值都存储在sqlite（应用程序内存）中，并创建一个密码并发送到用户提供的手机号码。下一个页面是注册页面，用户的用户名和密码和他收到的密码一起被检查。我做这个过程是为了验证手机号码。因此，我的问题是，一旦用户创建了帐户，返回登录选项并输入用户名和密码。。他正在引导到应用程序的第一页。。
