Я хочу создать более 1500 LyricsFullDetail в ListViewAdapter, но моя проблема в том, что я не хочу жестко кодировать полную информацию Lyrics в ListViewAdapter. java. Я хочу хранить все тексты песен и читать их из Strings. xml или папки с ресурсами. Файлы musi c сохраняются в папке raw. Я буду очень признателен, если вы поможете мне с примером fix.thanks Ниже приведены мои коды.
Это коды itemClick, которые я повторил 1500 раз, что дало мне «слишком большую ошибку кода»
Вот почему я изо всех сил пытаюсь сохранить его где-нибудь, как папка активов, и прочитать в ListViewAdapter
