        CharSequence contentText = "Hello World!";


        //notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        final int NOTIF_ID = 1234;
        NotificationManager notofManager = (NotificationManager)context. getSystemService(Context.NOTIFICATION_SERVICE);
        // Notification note = new Notification(R.drawable.face,"NEW ACTIVITY", System.currentTimeMillis());
        Intent notificationIntent = new Intent(context, Alset.class);
        PendingIntent contentIntent = PendingIntent.getActivity(context,0, notificationIntent, 0);
        Notification notification = new Notification(icon, tickerText,when );
        //Notification notification1 = new Notification(R.drawable.icon, "Wake up alarm", System.currentTimeMillis());
        notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
        notification.flags = Notification.FLAG_INSISTENT;
        notification.defaults |= Notification.DEFAULT_SOUND;
        //notification.setLatestEventInfo(context, "My Activity", "This will runs on button click", contentIntent);
        notofManager.notify(NOTIF_ID,notification);

        //PendingIntent contentIntent = PendingIntent.getActivity(context, 0, new Intent(context, MainActivity.class), 0);
        //notification.setLatestEventInfo(context, "Context Title", "Context text", contentIntent);
        //notification.flags = Notification.FLAG_INSISTENT;
    }

推荐答案

我认为您想将警报设置为6月26日而不是7月26日.如果是这样，则将 cal.set(Calendar.MONTH，6); 更改为 cal.set(Calendar.MONTH，5); ，因为月份是从零开始的.如果您打算在7月26日触发闹钟，那么预计闹钟将在日期时间为2011年7月26日17:30

I think you want to set the alarm for 26th June and not 26th July. If so then change cal.set(Calendar.MONTH,6); to cal.set(Calendar.MONTH,5); because the months are zero-based. if you intend the alarm to fire on 26th july then it is expected that the alarm will fire when the date-time is 26th July 2011, 17:30
