使用国家代码验证手机号码

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，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。它还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。

 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();
            }

但它不会为该数字返回 true。始终返回 false，即请输入正确的数字。

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>

如何做到这一点？谢谢。

试试这个例子...

android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity">

<EditText
    android:id="@+id/edtCountryCode"
    android:layout_width="wrap_content"

尝试使用PhoneNumberUtils 的isGlobalPhoneNumber() 方法来检测号码是否为有效电话号码。
