Question

Android开发新手。我想知道是否有可能以编程方式绘制一个图标放入通知栏？如果我们希望图标显示电池级别的动态文本怎么办？

如果有人有代码示例，那就太好了。感谢。

Answer 1

调用我们想要通知的功能。

 public void notification(String name) {

            final int id = 2;
            String ns = Context.NOTIFICATION_SERVICE;
            NotificationManager notificationManager = (NotificationManager) getSystemService(ns);
            int icon = R.drawable.fbc;
            CharSequence tickerText = "facebook";
            long when = System.currentTimeMillis();

            Notification checkin_notification = new Notification(icon, tickerText,
                    when);
            Context context = getApplicationContext();
            CharSequence contentTitle = "You are name is"+ name;
            CharSequence contentText = "Do You want to Check-in ?? ";

                Intent notificationIntent = new Intent(context, LoginTab.class);
                PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
                        notificationIntent, 0);
                checkin_notification.setLatestEventInfo(context, contentTitle,
                        contentText, contentIntent);
                checkin_notification.flags = Notification.FLAG_AUTO_CANCEL;
                notificationManager.notify(id, checkin_notification);

        }
