java如何在启动另一个音频时停止媒体播放器？
我正在尝试开发一个应用程序。此应用程序中有12个按钮。每个buton播放一个不同的音频。每三个按钮的颜色相同。我不想一起玩同样的颜色。但是我想和不同颜色的人一起玩
现在他们都在一起玩。我怎样才能停止播放相同的颜色

首先，您需要检查颜色是否相同
True或false boolean可以工作，但需要编写大量代码
我会推荐MediaPlayer的不同实例，比如mediaplayer1和mediaplayer2
相同的颜色在MediaPlayer的同一实例上运行。使用isplay（）检查当前是否播放相同的颜色。如果为真，则什么也不做；如果为假，则启动它。你会明白的
如果您的奥迪文件始终相同，SoundPool类也会有所帮助。SoundPool需要的代码比示例中的代码少得多，而且更可靠
