Android自定义Notification通知

效果图:

Activity中的代码:

//通过点击事件触发自定义的通知
    @Override
    public void onClick(View v) {
        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        SimpleDateFormat formatter = new SimpleDateFormat("HH:mm");
        Date curDate = new Date(System.currentTimeMillis());//获取当前时间
        String str = formatter.format(curDate);
        switch (v.getId()) {
            case R.id.start:
                Notification notification = new Notification(R.mipmap.ic_launcher,"title",System.currentTimeMillis());
//                FLAG_AUTO_CANCEL           该通知能被状态栏的清除按钮给清除掉
//                FLAG_NO_CLEAR                  该通知不能被状态栏的清除按钮给清除掉
//                FLAG_ONGOING_EVENT      通知放置在正在运行
                notification.flags = Notification.FLAG_ONGOING_EVENT;// 点击通知之后自动消失
                RemoteViews remoteView = new RemoteViews(this.getPackageName(), R.layout.layout_notification);
                remoteView.setImageViewResource(R.id.image, R.mipmap.ic_launcher_round);
                remoteView.setTextViewText(R.id.title, "标题:Notification    "+str);
                remoteView.setTextViewText(R.id.content, "前面我们说过，NotificationManager是所有Notification的大管家，它的主要职责是加入/移除Notification。");
//                remoteView.setTextViewText(R.id.nowTime,str );
                notification.contentView = remoteView;
                // 3、为Notification的contentIntent字段定义一个Intent(注意，使用自定义View不需要setLatestEventInfo()方法)
                //这儿点击后简答启动Settings模块
                PendingIntent contentIntent = PendingIntent.getActivity(MainActivity.this, 0, new Intent("android.settings.SETTINGS"), 0);
                notification.contentIntent = contentIntent;
                // 发送一个标识为100的通知
                notificationManager.notify(100,notification);
                // 发送一个标识为zjh和100的通知
//                notificationManager.notify("zjh",100,notification);
                break;

            case R.id.stop:
                //清除掉所有标识为100的通知
                notificationManager.cancel(100);
                //清除掉所有的通知
//                notificationManager.cancelAll();
                //清除掉所有标识为zjh和100的通知
//                notificationManager.cancel("zjh",100);
                break;

            default:
                break;
        }
    }
