1.注册UI及验证逻辑实现

1.1 布局

【说明】属于业务逻辑，登陆的业务逻辑，新建sign，新建类；

【注意】如果在ScrollView布局中如果嵌套了其他的布局，则其他的布局的layout_height属性应该为wrap_content;

【增加依赖】

1.2 注册信息的验证和逻辑

【布局控件的查找】

【输入注册信息的验证】

21 
22         boolean isPass = true;
23 
24         if (name.isEmpty()) {
25             mName.setError("请输入姓名");
26             isPass = false;
27         } else {
28             mName.setError(null);
29         }
30 
31         if (email.isEmpty() || !Patterns.EMAIL_ADDRESS.matcher(email).matches()) {
32             mEmail.setError("错误的邮箱格式");
33             isPass = false;
34         } else {
35             mEmail.setError(null);
36         }
37 
38         if (phone.isEmpty() || phone.length() != 11) {
39             mPhone.setError("手机号码错误");
40             isPass = false;
41         } else {
42             mPhone.setError(null);
43         }
44 
45         if (password.isEmpty() || password.length() < 6) {
46             mPassword.setError("请填写至少6位数密码");
47             isPass = false;
48         } else {
49             mPassword.setError(null);
50         }
51 
52         if (rePassword.isEmpty() || rePassword.length() < 6 || !(rePassword.equals(password))) {
53             mRePassword.setError("密码验证错误");
54             isPass = false;
55         } else {
56             mRePassword.setError(null);
57         }
58 
59         return isPass;
60     }

【测试】进入到注册的界面；
