android phonegap中的状态栏通知

Question

我在状态栏通知中有一个问题,间隔为10秒.我已经完成了代码,通过创建插件一次显示它.但我想每隔10分钟显示一次.所以我用它每10分钟AlarmManager生成一次通知但是它没有调用类的onReceive(Context ctx, Intent intent)方法FirstQuoteAlarm.我有以下代码用于显示通知和AlarmManager.

public void showNotification( CharSequence contentTitle, CharSequence contentText ) {
    int icon = R.drawable.nofication;
    long when = System.currentTimeMillis();

    Notification notification = new Notification(icon, contentTitle, when);

    Intent notificationIntent = new Intent(ctx, ctx.getClass());
    PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, notificationIntent, 0);
    notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

    mNotificationManager.notify(1, notification);

      Date dt = new Date();
      Date newdate = new Date(dt.getYear(), dt.getMonth(), dt.getDate(),10,14,dt.getSeconds());
      long triggerAtTime =  newdate.getTime();
      long repeat_alarm_every = 1000;
      QuotesSetting.ON = 1;

       AlarmManager am = ( AlarmManager )  ctx.getSystemService(Context.ALARM_SERVICE );
       //Intent intent = new Intent( "REFRESH_ALARM" );
       Intent intent1 = new Intent(ctx,FirstQuoteAlarm.class);
       PendingIntent pi = PendingIntent.getBroadcast(ctx, 0, intent1, 0 );
       am.setRepeating(AlarmManager.RTC_WAKEUP, triggerAtTime, repeat_alarm_every, pi);
       Log.i("call2","msg");


}

使用 ScheduledExecutorService。这通常会带来更好的结果。

它的目的是每隔几分钟在后台重复一次操作。从延迟开始等等。查看：http ://developer.android.com/reference/java/util/concurrent/ScheduledExecutorService.html

下面是一个类，其中的方法设置 ScheduledExecutorService 在一个小时内每十秒发出一次蜂鸣声：

import static java.util.concurrent.TimeUnit.*;
class BeeperControl {
private final ScheduledExecutorService scheduler =
 Executors.newScheduledThreadPool(1);

public void beepForAnHour() {
 final Runnable beeper = new Runnable() {
   public void run() { System.out.println("beep"); 
 };
 final ScheduledFuture beeperHandle =
   scheduler.scheduleAtFixedRate(beeper, 10, 10, SECONDS);
 scheduler.schedule(new Runnable() {
   public void run() { beeperHandle.cancel(true); }
 }, 60 * 60, SECONDS);
}
}}
