【问题描述】：
我在让我的音板应用程序正常运行时遇到了一些问题。我已经切换到使用这种方法而不是使用 MediaPlayer，因为 soundpool 是为这种应用程序设计的。然而，我遇到了这个应用程序的问题，当我点击一个按钮时，有时会播放声音，但不是一直播放。感觉很随意。
我有一个 OnLoadCompleteListener，它的状态为“0”，根据 SoundPool 类文档，这意味着成功。不过，情况似乎并非如此。我已经为应用程序中的按钮创建了所有正确的 OnClick 属性。我有大约 40 多种 .MP3 格式的声音，它们的平均容量都在 50 到 100kbs 之间。
我也在这个应用程序前面加载了一个启动画面，这让声音有更多时间在后台加载（我假设）。我已经在多个模拟器和实时设备上尝试过这个。这些声音似乎在 Nexus 设备上播放的频率更高，但在我迄今为止测试过的任何三星 Galaxies 和 OnePlus 设备上都没有。
感觉我已经非常接近完成这项工作了，所以任何简单的指针都会对我有很大帮助。再次感谢。这是我目前所拥有的：
