Android字段验证的实例代码

先给大家展示效果图：

}
//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

//手机号不能为空

// et_password2);
// 网址
/*Validate urlValidate = new Validate(et_url);

// 4. Form表单addValidates这个Validate类即可
form.addValidates(notPassword);

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