显示Android的通知每五分钟 [英] Show android notification every five minutes

问题描述

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);
    }

}
