Android - 如何将通知设置为未来的特定日期？ [英] Android - How to set a notification to a specific date in the future?

问题描述

编辑：SOLVED！想了解更多信息，了解如何操作：

pre> //在7天内设置通知
Calendar sevendayalarm = Calendar.getInstance（）;

sevendayalarm.add（Calendar.DATE，7）;

Intent intent = new Intent（this，Receiver.class）;
PendingIntent pendingIntent = PendingIntent.getBroadcast（this，001，intent，0）;

AlarmManager am =（AlarmManager）getSystemService（ALARM_SERVICE）;
am.set（AlarmManager.RTC_WAKEUP，sevendayalarm.getTimeInMillis（），pendingIntent）;

以下是Receiver类的代码

  public class Receiver extends Service {
 
 @Override 
 public IBinder onBind（Intent intent）{
 return null; 
} 
 
 @Override 
 public void onCreate（）{
 Intent intent = new Intent（this，Test.class）; 
 long [] pattern = {0，300，0}; 
 PendingIntent pi = PendingIntent.getActivity（this，01234，intent，0）; 
 NotificationCompat.Builder mBuilder = new NotificationCompat.Builder（this）
 .setSmallIcon（R.drawable.depressiontest）
 .setContentTitle（Take Questionnaire）
 .setContentText Duke Mood Study的调查问卷。）
 .setVibrate（pattern）
 .setAutoCancel（true）; 
 
 mBuilder.setContentIntent（pi）; 
 mBuilder.setDefaults（Notification.DEFAULT_SOUND）; 
 mBuilder.setAutoCancel（true）; 
 NotificationManager mNotificationManager =（NotificationManager）this.getSystemService（Context.NOTIFICATION_SERVICE）; 
 mNotificationManager.notify（01234，mBuilder.build（））; 
} 
} 
  

并且不要忘记添加以下权限清单！

 < uses-permission android：name =android.permission.VIBRATE/> 
< uses-permission android：name =android.permission.WAKE_LOCK/> 
< service android：name =。Receiver2android：enabled =true> 
< intent-filter> &action; action android：name =NOTIFICATION_SERVICE/>< / intent-filter> 
< / service> 
  

解决方案

不要忘记给予以下清单权限

 < uses-permission android：name =android.permission.VIBRATE/> 
< uses-permission android：name =android.permission.WAKE_LOCK/> 
  

您的广播接收者注册将如下

 < receiver android：name =。AlarmReceiver> 
< intent-filter> 
< action android：name =NOTIFICATION_SERVICE/> 
< / intent-filter> 
< / receiver> 
  

Edit: SOLVED! Ever wanted to set a notification from a specific date starting a certain point in time (when an activity is started or when a button is pressed?) Read more to find out how:

 //Set a notification in 7 days
                Calendar sevendayalarm = Calendar.getInstance();

                sevendayalarm.add(Calendar.DATE, 7);

                Intent intent = new Intent(this, Receiver.class);
                PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 001, intent, 0);

                AlarmManager am = (AlarmManager)getSystemService(ALARM_SERVICE);
                am.set(AlarmManager.RTC_WAKEUP, sevendayalarm.getTimeInMillis(), pendingIntent);

Here's the code for the Receiver class

public class Receiver extends Service {

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        Intent intent = new Intent(this, Test.class);
        long[] pattern = {0, 300, 0};
        PendingIntent pi = PendingIntent.getActivity(this, 01234, intent, 0);
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.depressiontest)
            .setContentTitle("Take Questionnaire")
            .setContentText("Take questionnaire for Duke Mood Study.")
            .setVibrate(pattern)
            .setAutoCancel(true);

        mBuilder.setContentIntent(pi);
        mBuilder.setDefaults(Notification.DEFAULT_SOUND);
        mBuilder.setAutoCancel(true);
        NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(01234, mBuilder.build());
    }
}

And don't forget to add the below permissions in the manifest!

<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
 <service android:name=".Receiver2" android:enabled="true">
        <intent-filter> <action android:name="NOTIFICATION_SERVICE" /></intent-filter>
    </service>

解决方案

Don't forget to give the below manifest permissions

<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

Your broadcast receiver registrations would be like this

   <receiver android:name=".AlarmReceiver" >
         <intent-filter>
           <action android:name="NOTIFICATION_SERVICE" />
         </intent-filter>
     </receiver>
