Ошибка: (145, 40) ошибка: не удается найти символьную переменную activity_maps

Question

Я пытаюсь реализовать внутреннее местоположение во втором основном действии. Я получаю следующие ошибки. Я хочу, когда вы нажмете кнопку внутренней навигации, чтобы иметь карту в помещении и показать свое местоположение в помещении. Спасибо заранее

Answer 1

Почему вы импортировать R из другого пакета? Из вашего кода я вижу, что вы импортируете R из com.lightcurb.example, который представляет собой другой пакет.

Таким образом удалить,

import com.lightcurb.example.R; 

от Вашего импорта.

Обратите внимание, что вам не нужно импортировать R, так как это файл R.java, который создается после успешного завершения сборки. И, если у вас есть какие-либо ошибки (т. Е. Красная подчеркивание под R), то это означает, что в вашем проекте есть некоторая ошибка сборки. Если, так что, пожалуйста, проверьте свои файлы xml, файлы градиента и т. Д.
