Question

我想验证用户输入的手机号码。我有两个编辑文本，一个用于代码，即+ 91,0等，另一个用于电话号码。

我有一个问题，即如果用户输入的数字超过10个，如何停止在编辑文本中输入数字。它也应该通过代码和数字进行验证。

我尝试使用此代码进行验证。

new Gson().toJson(user, ModelSendFilters.class)

但是这个数字并不是真的。始终返回false，即请输入正确的数字。

编辑数字文本：

 private boolean isValidMobile(String phone)
{
    return android.util.Patterns.PHONE.matcher(phone).matches();
}

 else if (!isValidMobile(code.getText().toString()+mobileNo.getText().toString()))
            {
                Toast.makeText(RegisterActivity.this,"Please enter correct Mobile No.",Toast.LENGTH_LONG).show();
            }

怎么做？谢谢。

Answer 1

尝试使用isGlobalPhoneNumber() PhoneNumberUtils方法检测某个号码是否为有效电话号码。
