У меня есть приложение, в котором у меня есть кнопка, текст заголовка которой отображает название страны и код при нажатии на нее. то есть отображается IN +91. при нажатии кнопки открывается всплывающее окно, в котором перечислены все страны с названием и кодом страны. Теперь, кроме этого, у меня есть текстовое поле номера мобильного телефона, которое будет отображать номер мобильного телефона при выборе из списка контактов. Рядом с мобильным текстовым полем у меня есть кнопка, которая открывает список контактов по умолчанию, теперь, что я хочу, скажем, я выбрал контакт, номер которого +919998536042, тогда номер 9998536042 должен отображаться в текстовом поле, а текст заголовка кнопки должен отображать IN + 91. то есть расширение из списка контактов должно совпадать с кодом страны в массиве списков стран, который я использовал для отображения списка стран. Пожалуйста, помогите мне. Я застрял. и еще одна вещь, скажем, я нажал на кнопку In +91 и выбрал, например, US +1, затем я выбрал контакт, который не имеет расширения, тогда текст заголовка кнопки останется таким же, как US +1, и если расширение найдено для пример +91, затем какое-то число, затем текст заголовка кнопки будет IN + 91
изображения моего приложения для лучшего понимания: 
, теперь нажимая IN +91, открывается вверх выбора, показанного на скриншоте 2
