通知栏设置

一般在service里设置

    

public static NotificationManager nm;

private String _title;
private String _artist;

/**
     * 当开始播放时，通知栏显示当前播放信息
     */
    private void ShowNotifcation() {
        nm = (NotificationManager) getApplicationContext().getSystemService(
                Context.NOTIFICATION_SERVICE);//获取通知栏系统服务对象
        notification = new Notification();// 实例化通知栏
        notification.icon = R.drawable.icon;// 为通知栏增加图标
        notification.defaults = Notification.DEFAULT_LIGHTS;// 默认灯
        notification.flags |= Notification.FLAG_AUTO_CANCEL;// 永远驻留
        notification.when = System.currentTimeMillis();// 获得系统时间
        notification.tickerText = _title;
        notification.tickerText = _artist;
        Intent intent2 = new Intent(getApplicationContext(),
                PlayMusicActivity.class);
        intent2.putExtra("_ids", _ids);
        intent2.putExtra("_titles", _titles);
        intent2.putExtra("_artists", _artists);
        intent2.putExtra("position", position);
        PendingIntent contentIntent = PendingIntent.getActivity(
                getApplicationContext(), 0, intent2,
                PendingIntent.FLAG_UPDATE_CURRENT);
        notification.setLatestEventInfo(getApplicationContext(), "播放中", _title,
                contentIntent);
        nm.notify(0, notification);

    }
