使用国家/地区代码验证手机号码 [英] Validate Mobile number with the country code

问题描述

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.

I want to validate the mobile number user enters. I have two edit texts one for the code i.e. +91,0 etc and another for the phone number.

我有一个问题，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.另外，还应使用代码和编号对其进行验证.

I have a question that how to stop entering the numbers in edit text if more than 10 numbers being entered by the user. Also it should get validated with code and the number.

我尝试使用此代码进行验证.

I tried the validation with this code.

 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();
            }

但是该数字不能返回true.始终返回false，即请输入正确的数字.

But it dose not return true for the number. Always returns false i.e. please enter the correct number.

编辑数字文本:

            <EditText
                android:layout_width="30dp"
                android:layout_height="match_parent"
                android:ems="10"
                android:id="@+id/editText_code"
                android:layout_marginLeft="20dp"
                android:background="@android:color/transparent"
                android:hint="+91"
                android:textSize="14sp"
                android:phoneNumber="true" />


      <EditText
                android:layout_width="match_parent"
                android:layout_height="40dp"
                android:hint="MOBILE NO"
                android:singleLine="false"
                android:layout_below="@+id/linearLayoutFirstName"
                android:layout_toRightOf="@+id/linearLayoutFirstName"
                android:layout_toEndOf="@+id/linearLayoutFirstName"
                android:background="@android:color/transparent"
                android:layout_gravity="center"
                android:textSize="12sp"
                android:layout_marginLeft="05dp"
                android:id="@+id/mobileNo"
                android:phoneNumber="true" />
        </LinearLayout>

如何执行此操作?谢谢.
