Я работаю на андроиде проект, где у меня есть 2 пользовательского кокКак изменить андроид: записи список массива в блеснах динамически в Android
- государственного
- Город
я использую ниже кода, чтобы заполнить счетчик с помощью пользовательского списка.
XML код:

android:layout_width="100dp"
android:layout_height="wrap_content"
android:entries="@array/state"

Приведенный выше код работает нормально, но мне нужно изменить массив во время выполнения. Массив объявляется в файле XML, как этот
android:entries="@array/state"
Как я могу изменить этот массив во время выполнения? Любая помощь была бы ценной.
- Спасибо!
