1.定义notification

private NotificationCompat.Builder mBuilder;

mBuilder = new NotificationCompat.Builder(MainActivity.this)
					.setSmallIcon(R.drawable.a)
					.setContentTitle("")
					.setContentText("");

2.添加点击notification跳转至activity

private Intent i_notifi;
private PendingIntent pi;

i_notifi = new Intent(this,MainActivity.class);
pi = PendingIntent.getActivity(this, 0, i_notifi, PendingIntent.FLAG_UPDATE_CURRENT);

mBuilder.setContentIntent(pi);

3.启动notification

private NotificationManager nm;

nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

nm.notify(001, mBuilder.build());

PS:点击notification后自动取消通知栏

mBuilder.setAutoCancel(true);

4.设置notification 显示多文字

Notification notif = new Notification.Builder(mContext)
     .setContentTitle("New mail from " + sender.toString())
     .setContentText(subject)
     .setSmallIcon(R.drawable.new_mail)
     .setLargeIcon(aBitmap)
     .setStyle(new Notification.BigTextStyle()
         .bigText(aVeryLongString))
     .build();
