Answer 5

目测是MusicService   start之后没有解绑的问题。

Answer 6

我把我的MusicService的完整代码放上来，麻烦帮我看下，谢谢

//private String path="";

//该服务不存在需要被创建时被调用，不管startService()还是bindService()都会启动时调用该方法
@Override
public void onCreate() {
super.onCreate();

mPlayer = MediaPlayer.create(getApplicationContext(), R.raw.pm);
mPlayer.start();
//设置可以重复播放
mPlayer.setLooping(true);
}

@Override

super.onDestroy();
}
//其他对象通过bindService 方法通知该Service时该方法被调用
@Override
