变量初始化：

	mIntent = new Intent(this, GinwaveIMusic.class);
	mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
	mPendingIntent = PendingIntent.getActivity(this, 0, mIntent, 0);
        //构造Notification对象
        mNotification = new Notification();
        mNotification.flags = Notification.FLAG_NO_CLEAR|Notification.FLAG_ONGOING_EVENT;;
        mNotification.icon = R.drawable.icon;

显示通知：

private void showNotification(){
	mNotification.when = System.currentTimeMillis();  
	mNotification.tickerText = mPresentSong.Song_Title;
	initializeNotificationView( mPresentSong.Song_Title, mPresentSong.Song_Player + "-" + mPresentSong.Song_Album, R.drawable.icon);
	mNotification.contentIntent = mPendingIntent;
	//mNotification.setLatestEventInfo(this, mPresentSong.Song_Title, mPresentSong.Song_Player + "-" + mPresentSong.Song_Album, mPendingIntent);
	mNotificationManager.notify(0, mNotification);
}
	
private void initializeNotificationView(String title, String content, int notificationImage) {
        RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.notification);
        contentView.setImageViewResource(R.id.notification_image, notificationImage);
        contentView.setTextViewText(R.id.notification_text_tiele, title);
        contentView.setTextViewText(R.id.notification_text_content, content);
        mNotification.contentView = contentView;
}

撤销通知：

private void dismissNotification(){
	mNotificationManager.cancel(0);
}

布局文件：

<?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/notification_image"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content" 
		/>
	<TextView 
		android:id="@+id/notification_text_tiele"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content"

	<TextView 
		android:id="@+id/notification_text_content"
