android中的布局和视图格式

Question

我创建了一个使用 google plus 登录的应用程序！因此，当我使用 google plus 登录时，它会显示获取的个人资料名称、电子邮件 ID 和个人资料图片！

但我的问题是布局或您可以说格式不正常！

我想要除了电子邮件 ID 和个人资料名称之外的个人资料图片！ 个人资料图片一直到页面的末尾，我必须使用滚动视图才能通过滚动来显示它，否则它不会显示！请帮忙 ！！我不能附上截图，因为它需要 10 个声望！！

看到了吗？ ，我必须向下滚动才能看到此按钮

相反，我希望格式是这种方式，特别是对于分辨率较低的小屏幕尺寸设备，因为这必须向下滚动
