通知在特定的时间，每天的Android

Question

我想打一个应用程序，让用户决定什么时候每天要他提醒与通知的东西...

我想知道我怎么在特定时间触发通知，用户想要在上午7:00之前让他点击通知并在特定活动中输入应用程序。但是，当用户不想再收到任何通知（点击按钮），我将如何取消所有通知...？

我做了类似

Intent intent = new Intent(this, main.class); 
Bundle bundle = new Bundle(); 
bundle.putString("title", "Some Title");\ 
intent.putExtras(bundle); 
PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0); 
String body = "Tap to see the Activity"; 
String title = "Title of notification"; 
Notification n = new Notification(R.drawable.ic_launcher, body, System.currentTimeMillis()); 
n.setLatestEventInfo(this, title, body, pi); 
n.defaults = Notification.DEFAULT_ALL; 
nm.notify(uniqueID, n); 

，但没有运气直到现在....

谢谢...

我这样做

 String ns = Context.NOTIFICATION_SERVICE; 
     NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); 

     int icon = R.drawable.notification_icon; 
     CharSequence tickerText = "Ome TickerText"; 
     long when = System.currentTimeMillis(); 
     Context context = getApplicationContext(); 
     CharSequence contentTitle = "Some Title"; 
     CharSequence contentText = "Some Text"; 

     Intent notificationIntent = new Intent(context, LandingActivity.class); 
     Bundle bundle = new Bundle(); 
     bundle.putString("title", "a title"); 
     bundle.putString("title2", "title number 2"); 
     bundle.putString("action", "tip"); 
     bundle.putString("greek", "somehting else"); 
     bundle.putInt("action_num", 2); 
     notificationIntent.putExtras(bundle); 
     alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); 
     contentIntent = PendingIntent.getActivity(Notifications.this, 0, notificationIntent, 0); 

     Notification notification = new Notification(icon, tickerText, when); 
     notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); 
     notification.defaults = Notification.DEFAULT_ALL; 

     mNotificationManager.notify(UniqueID, notification); 

     int hour = tp.getCurrentHour(); 
     int minutes = tp.getCurrentMinute(); 

     contentIntent = PendingIntent.getService(Notifications.this, 0, notificationIntent, 0); 
     AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); 
     Calendar calendar = Calendar.getInstance(); 
     calendar.setTimeInMillis(System.currentTimeMillis()); 
     calendar.set(Calendar.HOUR_OF_DAY, hour); 
     calendar.set(Calendar.MINUTE, minutes); 
     calendar.set(Calendar.SECOND, 00); 
     alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), contentIntent); 

但没有运气...

请帮忙吗？

使用alarm manager，并把您的通知中NotifyService类

Intent myIntent = new Intent(Current.this , NotifyService.class);  
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE); 
pendingIntent = PendingIntent.getService(ThisApp.this, 0, myIntent, 0); 
Calendar calendar = Calendar.getInstance(); 
calendar.set(Calendar.HOUR_OF_DAY, 12); 
calendar.set(Calendar.MINUTE, 00); 
calendar.set(Calendar.SECOND, 00); 
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY , pendingIntent); //set repeating every 24 hours

我知道这是一个老问题，但我也有类似的要求，这就是我所做的。我发现了当前系统时间与用毫秒发送通知的预期时间之间的差异，并在android服务中实现了可运行的时间。下面的代码将出现在NotifyService中。

private Handler notificationTimer = new Handler() { 
    @Override 
    public void handleMessage(Message msg) { 
     if(msg.what==0) { 
       sendNotifications(); 
     } 
     super.handleMessage(msg); 
    } 
}; 
private Runnable notificationCaller = new Runnable() { 

    @Override 
    public void run() { 
     Message msg = notificationTimer.obtainMessage(); 
     msg.what = 0; 
     notificationTimer.sendMessage(msg); 
    } 
};   


    Calendar calendar = Calendar.getInstance(); 
    Calendar timefornotification = Calendar.getInstance(); 
    timefornotification.set(Calendar.HOUR_OF_DAY, 12); 
    timefornotification.set(Calendar.MINUTE, 30); 
    timefornotification.set(Calendar.SECOND, 00); 

    Long difference = calendar.getTimeInMillis() - timefornotification.getTimeInMillis(); 

    if(difference<0){ 
     notificationTimer.postDelayed(notificationCaller, -(difference)); 
    } 
    else{ 
     notificationTimer.postDelayed(notificationCaller, difference); 
    } 

    public void sendNotifications(){ 
     ------Your code here------- 
     notificationTimer.removeCallbacksAndMessages(null); 
     notificationTimer.postDelayed(notificationCaller, 86400000); 
     ------86400000 is one day. So it will repeat everyday------- 
    } 

您可以再调用从主类服务在后台运行此。

Intent service = new Intent(this, NotifyService.class); 
    this.startService(service);
