Notification--通知

[android]代码库

1.创建一个Note的Activity

2.        Intent intent=new Intent(this,Note.class);
        PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);  //延迟执行
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        Notification notification=new NotificationCompat.Builder(this)
                .setContentTitle("通知标题")
                .setContentText("通知正文")
                .setWhen(System.currentTimeMillis()) //何时发出通知
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
                .setContentIntent(pi)
                .setDefaults(NotificationCompat.DEFAULT_ALL)
               // .setStyle(new NotificationCompat.BigPictureStyle().bigPicture(BitmapFactory.decodeResource(getResources(), R.drawable.big_image)))
                .setPriority(NotificationCompat.PRIORITY_MAX)
                .build();
        manager.notify(1, notification);  //参数(通知id ,Notification的实例对象)

3.点击通知后会跳转到Note的Activity
