java - 如何通过单击 android 中的按钮完成一个循环后继续 R.raw.audio 声音

Question

我的程序只工作一次，但我想每次都继续播放声音，我有 98 个音频，当我单击按钮和 1,2,3,.....97, 98 时，它播放得很好，但在 98 之后,1,2,3 第二个循环中不播放声音。如何在下一个循环中继续播放声音？我们将不胜感激您的帮助。谢谢 我的代码:

我认为您缺少 currentAudio 的翻转。

currentAudio = ++currentAudio % audios.length;
 AND
currentAudio = (--currentAudio + audios.length) % audios.length;
