Android字段验证的实例代码

先给大家展示效果图：

setContentView(R.layout.activity_main); 
initView(); 
setListener(); 
validateForm(); 
} 
//格式验证 
private void validateForm() { 
// 1. 先创建个表单Form类用来装控件 
form = new Form(); 
// 非空验证 
// 2. 然后创建Validate类，将被验证控件传入 
Validate notEmptyValidate = new Validate(etAccount); 
// 3. 将这个Validate类addValidator加入（如：非空类型NotEmptyVerifior）类型验证类 
NotEmptyValidator notEmpty = new NotEmptyValidator(this);

// 二选一 
OrTwoRequiredValidate orTwoRequiredValidate = new OrTwoRequiredValidate(

//密码验证

//城市不能为空

emailValidate.addValidator(emailValidator); 
// 重复密码确认 
// ConfirmValidate confirmValidate = new ConfirmValidate(et_password1, 
// et_password2); 
// 网址 
 
// 4. Form表单addValidates这个Validate类即可

// 5. 最后调用form.validate()验证即可，返回true表示验证通过。
