        builder.setContentTitle("标题");
        builder.setContentText("内容");
        builder.setSmallIcon(R.drawable.ic_launcher);

        progress+=10;
        if(progress>100){
            progress = 100;
            timer.cancel();　　
        }

        notification = builder.build();
        manager.notify(2, notification);
    }
}, 1000    , 1000);

自定义：

NotificationCompat.Builder builder = new NotificationCompat.Builder(MainActivity.this);
builder.setContentTitle("标题");
builder.setAutoCancel(true);
builder.setSmallIcon(R.drawable.ic_launcher);
// 创建RemoteView并显示在通知中
RemoteViews views = new RemoteViews(getPackageName(), // 当前所在应用的包
        R.layout.notification);
views.setTextViewText(R.id.textview, "普通文本");
views.setImageViewResource(R.id.image, R.drawable.ic_launcher);
builder.setContent(views);// 设置自定义的通知
notification = builder.build();
manager.notify(3, notification);
