HarmonyOS实战—实现注册登录和修改密码页面

文章目录

• 1. 注册登录页面
• 2. 修改密码页面

1. 注册登录页面

• 设置的要求如下：
  
• 新建项目：TextApplication
• 上面的数值单位都是 px ，所以要转换成 vp 和 fp
• 在 1920*1080 分辨率下，1px = 1/3vp
• P40：1080*2340 的分辨率跟上面的 1920*1080 差不多，所以就可以用1：3 的关系来转换
• 有关 px,vp,fp 三者的关系可以看看我之前写的博文：https://xdr630.blog.csdn.net/article/details/119299891
• 快速格式化页面对齐：Ctrl + Alt + L
