public class Notification extends Object
implements Parcelable java.lang.Object ???? android.app.Notification Class Overview

A class that represents how a persistent notification is to be presented to the user using theNotificationManager.

The Notification.Builder has been added to make it easier to construct Notifications.

1、創(chuàng)建NotificationManager對Notification進行管理：

NotificationManager?mNotificationManager?=?(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

2、創(chuàng)建Notification：

Notification?mNotification?=?new?Notification.Builder(getApplicationContext())
		.setContentTitle("notification")
		.setContentText("content")
		.setSmallIcon(R.drawable.ic_launcher)
		.setLargeIcon(mBitmap)
		.setContentIntent(mPendingIntent)
		.setDefaults(Notification.DEFAULT_ALL)
		.build();

3、用NotificationManager的notify()方法將通知顯示：

//void?android.app.NotificationManager.notify(int?id,?Notification?notification)
//id：?An?identifier?for?this?notification?unique?within?your?application.
	mNotificationManager.notify(2,mNotification);

此時Notification還不能響應點擊。

接下來用PendingIntent實現(xiàn)點擊：

Intent?intent?=?new?Intent(this,NotificationActivity.class);
//PendingIntent?android.app.PendingIntent.getActivity(Context?context,?int?requestCode,?Intent?intent,?int?flags)
PendingIntent?mPendingIntent?=?PendingIntent.getActivity(this,?0,?intent,?PendingIntent.FLAG_CANCEL_CURRENT);

用Notification.Builder.setContentIntent()：

Notification?mNotification?=?new?Notification.Builder(getApplicationContext())
		.setContentIntent(mPendingIntent)

部分關鍵代碼：

//getResources()在onCreate()里,否則報空指針context為空
		//Resources?android.content.Context.getResources()
		Intent?intent?=?new?Intent(this,NotificationActivity.class);
		//PendingIntent?android.app.PendingIntent.getActivity(Context?context,?int?requestCode,?Intent?intent,?int?flags)
		PendingIntent?mPendingIntent?=?PendingIntent.getActivity(this,?0,?intent,?PendingIntent.FLAG_CANCEL_CURRENT);
		//將qq.jpg轉(zhuǎn)化為Bitmap，使用它設置大圖標
		Bitmap?mBitmap=BitmapFactory.decodeResource(getApplicationContext().getResources(),?R.drawable.qq);
		NotificationManager?mNotificationManager?=?(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
		
		Notification?mNotification?=?new?Notification.Builder(getApplicationContext())
		.setContentTitle("notification")
		.setContentText("content")
		.setSmallIcon(R.drawable.ic_launcher)
		.setLargeIcon(mBitmap)
		.setContentIntent(mPendingIntent)
		.setDefaults(Notification.DEFAULT_ALL)
		.build();
		/*int?DEFAULT_ALL?Use?all?default?values?(where?applicable).?
		int?DEFAULT_LIGHTS?Use?the?default?notification?lights.?
		int?DEFAULT_SOUND?Use?the?default?notification?sound.?
		int?DEFAULT_VIBRATE?Use?the?default?notification?vibrate.?
		?*/
		/*setLights(int?argb,?int?onMs,?int?offMs)?
Set?the?desired?color?for?the?indicator?LED?on?the?device,?as?well?as?the?blink?duty?cycle?(specified?in?milliseconds).
		setSound(Uri?sound)?
Set?the?sound?to?play.
setVibrate(long[]?pattern)?
Set?the?vibration?pattern?to?use.
long[]?vibrates={0,1000,1000,1000}?notification到來時震動1s停止1s再震動1s
vibrates[0]:靜止時長
vibrates[1]:振動時長
vibrates[2]：靜止時長
....?*/
		//void?android.app.NotificationManager.notify(int?id,?Notification?notification)
		//id：?An?identifier?for?this?notification?unique?within?your?application.
		mNotificationManager.notify(2,mNotification);		

將qq.jpg轉(zhuǎn)化為Bitmap

Bitmap?mBitmap=BitmapFactory.decodeResource(getApplicationContext().getResources(),?R.drawable.qq);

還可以設置Notification到來時的振動，聲音，燈光效果
Notification.Builder setLights(int argb, int onMs, int offMs)Set the desired color for the indicator LED on the device, as well as the blink duty cycle (specified in milliseconds). Notification.Builder setSound(Uri sound)Set the sound to play. Notification.Builder setVibrate(long[] pattern)Set the vibration pattern to use. 或者：

Notification.Builder setDefaults(int defaults)Set which notification properties will be inherited from system defaults.
