我遇到的问题是检查声音文件何时加载。在onCreate方法中,请注意最后一个while循环。理论上,据我所知,一旦加载了声音,代码就应该继续。然而,应用程序永远不会离开while循环,并且会一直在其中迭代。我相信我可能误解了声音池的onLoadCompleteListener,并错误地实现了它。我想确保我的应用程序不会离开onCreate方法,直到五种声音全部加载完毕
我发现,确保我想要的声音只在加载后播放的唯一方法是使用onStart方法中显示的while循环。在加载之前,play方法始终返回零。但是,我不喜欢这种方法,因为每次我想播放声音时都必须使用这种方法。可能效率也很低。我决定使用MediaPlayer。以使用更多资源为代价,相对容易的实现和更广泛的控制播放的方法保证了这种转变 以下是我的实施的简要概述:
MediaPlayer mediaPlayer = MediaPlayer.create(this, R.raw.readysetgo);
...
mediaPlayer.start();
while (mediaPlayer.isPlaying()) {} //wait until finished to move on
