设置自定义通知栏无效

设置CustomPushNotificationBuilder = new CustomPushNotificationBuilder(this,R.layout.jpush_notification_layout,R.id.icon,R.id.title,R.id.text);
builder.statusBarDrawable = R.drawable.push_notification;
builder.layoutIconDrawable = R.drawable.push_notification;
JPushInterface.setPushNotificationBuilder(2,builder);
后，发送通知栏编号为2的通知，在app中能接受到，但是通知栏里面不显示。发送默认的通知可以接受到，并且在状态栏中显示

另外，res中设置了res/drawable-xxxx/jpush_notification_icon这个文件，但是jpush_notification_icon不显示
