Question

我正在创建一个包含firstname, lastname ,gender,date of birth,address1,address2 and mobile number的用户个人资料片段。

在这里，我的程序无法验证电话号码。即使我在手机号码字段中输入了10位数字，也会出现输入有效号码的错误。

这是我的代码。

Answer 1

删除此条件->

else if(!mobile_no.matches("[a-zA-Z]+")|| mobile_no.length()!=10){
                edittext_mob.setError("ENTER VALID NUMBER");
            }

并对其进行修改：

else if(mobile_no.length()!=10){
                edittext_mob.setError("ENTER VALID NUMBER");
            }

并在您初始化此editText的地方定义提及的那一行->

mobile_no.setInputType（InputType.TYPE_CLASS_NUMBER）;

Answer 2

更改

if(!mobile_no.matches("[a-zA-Z]+")|| mobile_no.length()!=10)

此

if(!mobile_no.matches("\\d+")|| mobile_no.length()!=10)

Answer 3

为什么要检查字符模式？试试这个

if(!(mobileNo.matches("\\d+")) || mobileNo.length != 10){
// Your message here
}

Answer 4

 else if(!mobile_no.matches("[a-zA-Z]+")|| mobile_no.length()!=10){
                    edittext_mob.setError("ENTER VALID NUMBER");

                }

此条件表明，如果mobile_no与“ a-z”或“ A-Z”不匹配，或者mobile_no.length不等于10，则显示错误
尝试删除“！”处于第一状态

else if(mobile_no.matches("[a-zA-Z]+")|| mobile_no.length()!=10){
                edittext_mob.setError("ENTER VALID NUMBER");

            }
