Android dialog能设置延迟或者倒计时吗?

Question

protected void dialog() {
AlertDialog.Builder builder = new Builder(VideoViewActivity.this);
builder.setMessage("是否进入下一视频");

builder.setTitle("提示");

builder.setPositiveButton("确认", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
CategoryVideo categoryvideo = new CategoryVideo();
categoryvideo.runnext();

}

});

builder.setNegativeButton("取消", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();

}
});

builder.create().show();

现在做个播放器 需求是一首歌结束后弹出dialog是否进入下一首，如果不选择那么10秒后自动跳的下一首。
应该怎么做呢？？？？基本的已完成，求教高手~~~~~~~~~
