我想知道如何设置时间的通知。我想设置的通知每五分钟， 所以帮我做的。

公共类FirstActivity扩展活动 {     私有静态最终诠释HELLO_ID = 1;     //公共静态最终诠释FLAG_AUTO_CANCEL = 0;`输入code here`     @覆盖     保护无效的onCreate（包savedInstanceState）{         // TODO自动生成方法存根         super.onCreate（savedInstanceState）;         的setContentView（R.layout.firstactivity）;         字符串NS = Context.NOTIFICATION_SERVICE;         NotificationManager mNotificationManager =（NotificationManager）getSystemService（NS）;         INT图标= R.drawable.icon;         CharSequence的tickerText =你好;         时长= System.currentTimeMillis的（）;         通知通知=新的通知（图标，tickerText时）;         RemoteViews内容查看=新RemoteViews（getPackageName（），R.layout.statusbarnotification）;         contentView.setImageViewResource（R.id.image，R.drawable.icon）;         contentView.setTextViewText（R.id.text，你好，这条消息是在自定义扩展视图）;         notification.contentView =内容查看;         notification.flags = Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL;         意图notificationIntent =新的意图（getApplicationContext（），SecondActivity.class）;         // PendingIntent contentIntent = PendingIntent.getActivity（此，0，notificationIntent，0）;         PendingIntent contentIntent = PendingIntent.getActivity（此，0，notificationIntent，0）;         notification.contentIntent = contentIntent;         mNotificationManager.notify（HELLO_ID，通知）;     } }

解决方案

我认为最好的办法就是创建设置通知的服务，然后激活使用AlarmManager服务。 这是在code为AlarmManager：

私人无效startAlarm（）{     AlarmManager alarmManager =（AlarmManager）this.getSystemService（this.ALARM_SERVICE）;     时长= System.currentTimeMillis的（）; //通知时间     意向意图=新的意图（这一点，ReminderService.class）;     PendingIntent pendingIntent = PendingIntent.getService（此，0，意图，0）;     alarmManager.setRepeating（AlarmManager.RTC，当，（AlarmManager.INTERVAL_FIFTEEN_MINUTES / 3），pendingIntent）; }

要控制时间间隔使用常量或只需插入自己的值（以毫秒为单位）。

下面的服务：

公共类ReminderService扩展IntentService {     私有静态最终诠释NOTIF_ID = 1;     公共ReminderService（）{         超级（ReminderService）;     }     @覆盖       保护无效onHandleIntent（意向意图）{         NotificationManager纳米=（NotificationManager）getSystemService（Context.NOTIFICATION_SERVICE）;         时长= System.currentTimeMillis的（）; //通知时间         通知通知=新的通知（R.drawable.icon，提醒，当）;         notification.defaults | = Notification.DEFAULT_SOUND;         notification.flags | = notification.FLAG_AUTO_CANCEL;         意图notificationIntent =新的意图（这一点，YourActivity.class）;         PendingIntent contentIntent = PendingIntent.getActivity（此，0，notificationIntent，0）;         notification.setLatestEventInfo（getApplicationContext（），是时候，你现在应该打开应用程序，contentIntent）;         nm.notify（NOTIF_ID，通知）;     } }

I want to know how to set time for notification. I want to set notification every five minutes, so help me do that.

public class FirstActivity extends Activity { private static final int HELLO_ID = 1; //public static final int FLAG_AUTO_CANCEL = 0;`enter code here` @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.firstactivity); String ns = Context.NOTIFICATION_SERVICE; NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); int icon = R.drawable.icon; CharSequence tickerText = "Hello"; long when = System.currentTimeMillis(); Notification notification = new Notification(icon, tickerText, when); RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.statusbarnotification); contentView.setImageViewResource(R.id.image, R.drawable.icon); contentView.setTextViewText(R.id.text, "Hello, this message is in a custom expanded view"); notification.contentView = contentView; notification.flags = Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL; Intent notificationIntent = new Intent(getApplicationContext(), SecondActivity.class); //PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.contentIntent = contentIntent; mNotificationManager.notify(HELLO_ID, notification); } }

解决方案

I think that the best way will be to create a service that sets the notification and then activate the service using AlarmManager. That's the code for the AlarmManager:

private void startAlarm() { AlarmManager alarmManager = (AlarmManager) this.getSystemService(this.ALARM_SERVICE); long when = System.currentTimeMillis(); // notification time Intent intent = new Intent(this, ReminderService.class); PendingIntent pendingIntent = PendingIntent.getService(this, 0, intent, 0); alarmManager.setRepeating(AlarmManager.RTC, when, (AlarmManager.INTERVAL_FIFTEEN_MINUTES / 3), pendingIntent); }

To control the interval use the constant values or just insert your own value (in milliseconds).

Here is the Service:

public class ReminderService extends IntentService { private static final int NOTIF_ID = 1; public ReminderService(){ super("ReminderService"); } @Override protected void onHandleIntent(Intent intent) { NotificationManager nm = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); long when = System.currentTimeMillis(); // notification time Notification notification = new Notification(R.drawable.icon, "reminder", when); notification.defaults |= Notification.DEFAULT_SOUND; notification.flags |= notification.FLAG_AUTO_CANCEL; Intent notificationIntent = new Intent(this, YourActivity.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent , 0); notification.setLatestEventInfo(getApplicationContext(), "It's about time", "You should open the app now", contentIntent); nm.notify(NOTIF_ID, notification); } }
