Невозможно различить два фрагмента с событиями щелчка диаграммы

Question

Я реализовал две круговые диаграммы в двух разных фрагментах. Всякий раз, когда я нажимаю на круговую диаграмму, она вызывает события щелчка второго фрагмента на обоих фрагментах.

Вот мой код MainActivity.java.

Answer 1

К сожалению, сейчас мы не знаем, что именно происходит с диспетчеризацией событий во фрагментах. Но я хотел бы обратить ваше внимание на то, что существует возможный обходной путь. Щелчок на диаграмме возвращает правильное имя и значение точки. Только название фрагмента неверно. Имя жестко закодировано в обработчике события щелчка. Так что если имя фрагмента не требуется в выводе, вы можете просто удалить его. Если имя требуется, вы можете применить конкретный идентификатор к фрагменту, а затем получить этот идентификатор из представления активного фрагмента. Это должно решить проблему как временное решение.
