problem with 4 character country code

还没有人认领这个 Issue。

Hello! My problem is that I want to change the country code "Jamaica" from "+1" to "+1876", but when choosing a country code with a length of 4, the formatting fails, the last 4 digit of the country code goes to the edittext, and the formatting does not work right. Not to mention that the method "getfullnumberwithplus" country code remains "+1" and not "+1876" . I ask for help, preferably an ambulance). Thanks in advance.

选择 Jamaica 并将其国家代码从 +1 更改为 +1876，以重现该问题，然后跟踪 getfullnumberwithplus 周围的国家代码选择和电话号码格式化流程。当四字符代码保持完整、格式化正确使用 +1876，并且 getfullnumberwithplus 返回更新后的代码时，即表示完成。
