播放歌曲改变后，先将前一个播放的进度线程移除handler,
释放资源，解除绑定，重新绑定
binder.dorevmo();//handle.removeCallbacks(runnable);
binder.doRset();//mp.release();
unbindService(conn);
in.putExtra("path", m.get("path"));
bindService(in, conn, Context.BIND_AUTO_CREATE);
使用一个线程来执行seekbar的初始化，和播放完成回调方法的设置
new Thread(new Runnable() {//初始化seekbar
@Override
public void run() {
// TODO Auto-generated method stub
try {
Thread.sleep(500);
if (binder != null) {
binder.init(seekbar, new onMusicOver() {
@Override
public void onMusicOver() {
// TODO Auto-generated method stub
next(null);
}
});
