Android-Notification通知简单应用

Notification的简单应用

使通知显示在顶部，并跳转

public void send(View view) {
        Notification.Builder builder = new Notification.Builder(this);
        builder.setSmallIcon(R.mipmap.ic_launcher);//必须要有的属性，不然会报错
        builder.setContentTitle("标题");
        builder.setContentText("内容");
        builder.setWhen(System.currentTimeMillis());
        builder.setAutoCancel(true);//设置通知阅读完自动取消
        //让通知弹出
        builder.setPriority(Notification.PRIORITY_MAX);
        //让通知加上声音，灯光和震动
        builder.setDefaults(Notification.DEFAULT_ALL);
        //点击通知跳转
        Intent intent=new Intent(this,Main2Activity.class);
        //去哪里就get哪里
        PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,0);
        builder.setContentIntent(pendingIntent);
        //放大的图片
        builder.setLargeIcon(BitmapFactory.decodeResource(getResources(),R.mipmap.ic_launcher));

        Notification build = builder.build();
        //通知管理者
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        //发送通知 不同id代表发送，相同id代表更新
        manager.notify(1,build);
    }

使用自定义布局通知

public void send2(View view) {
        Notification.Builder builder = new Notification.Builder(this);
        builder.setSmallIcon(R.mipmap.ic_launcher);
        builder.setContentTitle("通知头");
        builder.setContentText("内容");

        builder.setAutoCancel(true);//设置通知阅读完自动取消
        //让通知弹出
        builder.setPriority(Notification.PRIORITY_MAX);
        //让通知加上声音，灯光和震动
        builder.setDefaults(Notification.DEFAULT_ALL);
        //点击通知跳转
        Intent intent=new Intent(this,Main2Activity.class);
        //去哪里就get哪里
        PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,0);

        //在系统通知栏中执行的，所有要远程访问我们的布局文件
        RemoteViews remoteViews = new RemoteViews(getPackageName(), R.layout.notifity);
        //加载布局文件
        builder.setCustomContentView(remoteViews);
        Notification build = builder.build();
        //通知管理者
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(2,build);

    }

进度条通知

public void send4(View view) {
        //通知管理者
        final NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        final Notification.Builder builder = new Notification.Builder(this);
        builder.setSmallIcon(R.mipmap.ic_launcher);
        builder.setContentTitle("和平精英");
        builder.setContentText("正在下载...");

        final Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            int index=0;
            @Override
            public void run() {
                index+=10;
                builder.setProgress(100,index,false);
                manager.notify(2, builder.build());
                if (index>100){
                    builder.setContentText("正在安装...");
                    builder.setProgress(100,index,true);
                    manager.notify(2, builder.build());
                    try {
                        Thread.sleep(3000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                    manager.cancel(2);
                    timer.cancel();
                }
            }
        },0,1000);


        Notification build = builder.build();


        manager.notify(2,build);
    }

通知分组

 public void send6(View view) {
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        Notification.Builder builder = new Notification.Builder(this);
        builder.setGroup("2");
        //builder.setGroupSummary(true);
        builder.setSmallIcon(R.mipmap.ic_launcher);
        builder.setContentTitle("1111");
        builder.setContentText("2222");

        Notification.Builder builder2 = new Notification.Builder(this);
        builder2.setGroup("2");
        builder2.setSmallIcon(R.mipmap.ic_launcher);
        builder2.setContentTitle("333");
        builder2.setContentText("2444222");
        Notification.Builder builder3 = new Notification.Builder(this);
        builder3.setGroup("2");
        builder3.setSmallIcon(R.mipmap.ic_launcher);
        builder3.setContentTitle("1155511");
        builder3.setContentText("2266622");


        manager.notify(1,builder.build());
        manager.notify(2,builder2.build());
        manager.notify(3,builder3.build());

    }

展示大图及多行文字通知

public void send5(View view) {
        Notification.Builder builder = new Notification.Builder(this);
        builder.setSmallIcon(R.mipmap.ic_launcher);
        builder.setContentTitle("通知头");
        builder.setContentText("内容");

        Notification.BigPictureStyle bigPictureStyle = new Notification.BigPictureStyle();
        bigPictureStyle.bigPicture(BitmapFactory.decodeResource(getResources(),R.mipmap.ic_launcher));
//        Notification.InboxStyle inboxStyle = new Notification.InboxStyle();
//        inboxStyle.addLine("hhh1");
//        inboxStyle.addLine("hhh1");
//        inboxStyle.addLine("hhh1");
        builder.setStyle(bigPictureStyle);
        Notification build = builder.build();
        //通知管理者
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        manager.notify(3,build);
    }
