//创建一个NotificationManager的引用

String ns = Context.NOTIFICATION_SERVICE;

NotificationManager mNotificationManager = (NotificationManager)getSystemService(ns);

//定义Notification的各种属性

int icon = R.drawable.icon; //通知图标

CharSequence tickerText = "Hello"; //状态栏显示的通知文本提示

long when = System.currentTimeMillis(); //通知产生的时间，会在通知信息里显示

//用上面的属性初始化Nofification

Notification notification = new Notification(icon,tickerText,when);

/*

* 添加声音

* notification.defaults |=Notification.DEFAULT_SOUND;

* 或者使用以下几种方式

* notification.sound = Uri.parse("file:///sdcard/notification/ringer.mp3");

* notification.sound = Uri.withAppendedPath(Audio.Media.INTERNAL_CONTENT_URI, "6");

* 如果想要让声音持续重复直到用户对通知做出反应，则可以在notification的flags字段增加"FLAG_INSISTENT"

* 如果notification的defaults字段包括了"DEFAULT_SOUND"属性，则这个属性将覆盖sound字段中定义的声音

*/

/*

* 添加振动

* notification.defaults |= Notification.DEFAULT_VIBRATE;

* 或者可以定义自己的振动模式：

* long[] vibrate = {0,100,200,300}; //0毫秒后开始振动，振动100毫秒后停止，再过200毫秒后再次振动300毫秒

* notification.vibrate = vibrate;

* long数组可以定义成想要的任何长度

* 如果notification的defaults字段包括了"DEFAULT_VIBRATE",则这个属性将覆盖vibrate字段中定义的振动

*/

/*

* 添加LED灯提醒

* notification.defaults |= Notification.DEFAULT_LIGHTS;

* 或者可以自己的LED提醒模式:

* notification.ledARGB = 0xff00ff00;

* notification.ledOnMS = 300; //亮的时间

* notification.ledOffMS = 1000; //灭的时间

* notification.flags |= Notification.FLAG_SHOW_LIGHTS;

*/

/*

* 更多的特征属性

* notification.flags |= FLAG_AUTO_CANCEL; //在通知栏上点击此通知后自动清除此通知

* notification.flags |= FLAG_INSISTENT; //重复发出声音，直到用户响应此通知

* notification.flags |= FLAG_ONGOING_EVENT; //将此通知放到通知栏的"Ongoing"即"正在运行"组中

* notification.flags |= FLAG_NO_CLEAR; //表明在点击了通知栏中的"清除通知"后，此通知不清除，

* //经常与FLAG_ONGOING_EVENT一起使用

* notification.number = 1; //number字段表示此通知代表的当前事件数量，它将覆盖在状态栏图标的顶部

* //如果要使用此字段，必须从1开始

* notification.iconLevel = ; //

*/

//设置通知的事件消息

Context context = getApplicationContext(); //上下文

CharSequence contentTitle = "My Notification"; //通知栏标题

CharSequence contentText = "Hello World!"; //通知栏内容

Intent notificationIntent = new Intent(this,Main.class); //点击该通知后要跳转的Activity

PendingIntent contentIntent = PendingIntent.getActivity(this,0,notificationIntent,0);

notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

//把Notification传递给NotificationManager

mNotificationManager.notify(0,notification);

//1、创建一个自定义的消息布局 view.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="fill_parent" android:layout_height="fill_parent">

<ImageView android:id="@+id/image" android:layout_width="wrap_content"

android:layout_height="fill_parent" android:layout_marginRight="10dp" />

<TextView android:id="@+id/text" android:layout_width="wrap_content"

android:layout_height="fill_parent" android:textColor="#000" />

</LinearLayout>

//2、在程序代码中使用RemoteViews的方法来定义image和text。然后把RemoteViews对象传到contentView字段

RemoteViews contentView = new RemoteViews(getPackageName(),R.layout.view);

contentView.setImageViewResource(R.id.image,R.drawable.icon);

contentView.setTextViewText(R.id.text,”Hello,this message is in a custom expanded view”);

notification.contentView = contentView;

//3、为Notification的contentIntent字段定义一个Intent(注意，使用自定义View不需要setLatestEventInfo()方法)

Intent notificationIntent = new Intent(this,Main.class);

PendingIntent contentIntent = PendingIntent.getActivity(this,0,notificationIntent,0);

notification.contentIntent = contentIntent;

//4、发送通知

mNotificationManager.notify(2,notification);

//以下是全部示例代码

//创建一个NotificationManager的引用

String ns = Context.NOTIFICATION_SERVICE;

NotificationManager mNotificationManager = (NotificationManager)getSystemService(ns);

//定义Notification的各种属性

int icon = R.drawable.icon; //通知图标

CharSequence tickerText = "Hello"; //状态栏显示的通知文本提示

long when = System.currentTimeMillis(); //通知产生的时间，会在通知信息里显示

//用上面的属性初始化Nofification

Notification notification = new Notification(icon,tickerText,when);

RemoteViews contentView = new RemoteViews(getPackageName(),R.layout.view);

contentView.setImageViewResource(R.id.image, R.drawable.iconempty);

contentView.setTextViewText(R.id.text, "Hello,this is JC");

notification.contentView = contentView;

Intent notificationIntent = new Intent(this,Main.class);

PendingIntent contentIntent = PendingIntent.getActivity(this,0,notificationIntent,0);

notification.contentIntent = contentIntent;

//把Notification传递给NotificationManager

mNotificationManager.notify(0,notification);
