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);
