安卓AlarmManager：如何避免去掉过去报警 [英] Android AlarmManager: how to avoid to going off of past alarms

问题描述

你好，感谢你的帮助。

我有一个使用AlarmManager每天设定一个报警的下一个星期的应用程序，数月......

• 我为一周的每一天设定一个报警启动活动

和

• 在一个报警为一周的每一天后停止活动 一段时间

我有以下问题，我会尝试在下面几行说明：

今天是周三，

我打开应用程序，并设置我的报警周一，周二，周三，周四，周五，周六，周日... 当我设置了报警：

所有报警的MON和TUE马上去关我结束了活动的4个实例!!!!

请我该如何避免这种情况？？？

请参见我的一块code：

  //设置了报警的启动活动
        意图SMON =新的意图（ctxt，VideoActivty.class）;
        smon.setFlags（Intent.FLAG_ACTIVITY_SINGLE_TOP）;
        PendingIntent psmon = PendingIntent.getActivity（ctxt，0，SMON，0）;

        日历calSet = Calendar.getInstance（）;
        calSet.set（Calendar.DAY_OF_WEEK，2）;
        calSet.set（Calendar.HOUR_OF_DAY，hsmon）;
        calSet.set（Calendar.MINUTE，msmon）;
        calSet.set（Calendar.SECOND，0）;
        calSet.set（Calendar.MILLISECOND，0）;

        mgr.setRepeating（AlarmManager.RTC_WAKEUP，calSet.getTimeInMillis（），
                7 * 24 * 60 * 60 * 1000，psmon）;

        //设置了报警的查杀活动
        意图FMON =新的意图（ctxt，VideoActivty.class）;
        fmon.putExtra（完成，真正的）;
        PendingIntent PFMON = PendingIntent.getActivity（ctxt，0，FMON，0）;

        calSet.set（Calendar.DAY_OF_WEEK，2）;
        calSet.set（Calendar.HOUR_OF_DAY，hfmon）;
        calSet.set（Calendar.MINUTE，mfmon）;
        calSet.set（Calendar.SECOND，0）;
        calSet.set（Calendar.MILLISECOND，0）;

        mgr.setRepeating（AlarmManager.RTC_WAKEUP，calSet.getTimeInMillis（），
                7 * 24 * 60 * 60 * 1000，PFMON）;
 

这是该活动：

            PowerManager.PARTIAL_WAKE_LOCK，）;
    wl.acquire（）;

    KeyguardManager公里=（KeyguardManager）getSystemService（Context.KEYGUARD_SERVICE）;
    键盘锁= km.newKeyguardLock（MyApp的）;
    keyguard.disableKeyguard（）;

    。getWindow（）和setFormat（PixelFormat.TRANSLUCENT）;
    VideoView videoHolder =新VideoView（本）;
    //如果你想控制出现
    videoHolder.setMediaController（新的MediaController（本））;
    乌里视频= Uri.parse（android.resource：//+ getPackageName（）+/
    + R.raw.ingress）; //不添加任何扩展
    //如果您的文件被命名为sherif.mp4并放置在/生
    //使用R.raw.sherif
    videoHolder.setVideoURI（视频）
    的setContentView（videoHolder）;

    videoHolder.start（）;
    videoHolder.setOnCompletionListener（新MediaPlayer.OnCompletionListener（）{

        @覆盖
        公共无效onCompletion（MediaPlayer的MP）{

                        mp.start（）;
        }
    }）;
}


@覆盖
保护无效onNewIntent（意向我）{


  如果（i.getBooleanExtra（完成，FALSE））{
      wl.release（）;
      keyguard.reenableKeyguard（）;
      完（）;
  }
}


}
 

解决方案

我们是否有办法解决吗？我仍然在寻找解决办法，我的code如下..

  calendar.set（Calendar.DAY_OF_WEEK，getweekday（OBJ））;
    calendar.set（Calendar.HOUR_OF_DAY，timepicker.getCurrentHour（））;
    calendar.set（Calendar.MINUTE，timepicker.getCurrentMinute（））;
    calendar.set（Calendar.SECOND，0）;
    calendar.set（Calendar.MILLISECOND，0）;
    如果（calendar.before（cal_now））{//如果在过去的增量
        calendar.add（Calendar.DATE，1）;
    }

PendingIntent发送= PendingIntent.getBroadcast（getApplicationContext（），_ ID，意图，PendingIntent.FLAG_UPDATE_CURRENT）;

    AlarmManager AM =（AlarmManager）getSystemService（ALARM_SERVICE）;
    am.setRepeating（AlarmManager.RTC_WAKEUP，calendar.getTimeInMillis（），AlarmManager.INTERVAL_DAY * 7，发送方）;
 

Hi and thank you for your help.

I have an application that uses AlarmManager to set one alarm a day for the next weeks, months...

• I set one alarm for each day of the week to start the Activity

and

• one alarm for each day of the week for stopping the Activity after some time

I have the following problem that I will try to explain in the following lines:

Today is Wednesday,

I open the application and set my alarms for MON, TUE, WED, THU, FRI, SAT, SUN... as soon as I set the alarms:

ALL the alarms for MON and TUE go immediately off I end up with 4 instances of the Activity !!!!

Please how do I avoid this???

Please see a piece of my code:

        // SET THE ALARM FOR STARTING THE ACTIVITY 
        Intent smon = new Intent(ctxt, VideoActivty.class);
        smon.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent psmon = PendingIntent.getActivity(ctxt, 0, smon, 0);

        Calendar calSet = Calendar.getInstance();
        calSet.set(Calendar.DAY_OF_WEEK, 2);
        calSet.set(Calendar.HOUR_OF_DAY, hsmon);
        calSet.set(Calendar.MINUTE, msmon);
        calSet.set(Calendar.SECOND, 0);
        calSet.set(Calendar.MILLISECOND, 0);

        mgr.setRepeating(AlarmManager.RTC_WAKEUP, calSet.getTimeInMillis(),
                7 * 24 * 60 * 60 * 1000, psmon);

        // SET THE ALARM FOR KILLING THE ACTIVITY 
        Intent fmon = new Intent(ctxt, VideoActivty.class);
        fmon.putExtra("finish", true);
        PendingIntent pfmon = PendingIntent.getActivity(ctxt, 0, fmon, 0);

        calSet.set(Calendar.DAY_OF_WEEK, 2);
        calSet.set(Calendar.HOUR_OF_DAY, hfmon);
        calSet.set(Calendar.MINUTE, mfmon);
        calSet.set(Calendar.SECOND, 0);
        calSet.set(Calendar.MILLISECOND, 0);

        mgr.setRepeating(AlarmManager.RTC_WAKEUP, calSet.getTimeInMillis(),
                7 * 24 * 60 * 60 * 1000, pfmon);

This is the Activity:

public class VideoActivty extends Activity {
private VideoView video;
private MediaController ctlr;
private PowerManager.WakeLock wl;
private KeyguardLock keyguard;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //
    PowerManager pm = (PowerManager) this
            .getSystemService(this.POWER_SERVICE);
    wl = pm.newWakeLock(
            PowerManager.PARTIAL_WAKE_LOCK, "");
    wl.acquire();

    KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
    keyguard = km.newKeyguardLock("MyApp");
    keyguard.disableKeyguard();

    getWindow().setFormat(PixelFormat.TRANSLUCENT);
    VideoView videoHolder = new VideoView(this);
    //if you want the controls to appear
    videoHolder.setMediaController(new MediaController(this));
    Uri video = Uri.parse("android.resource://" + getPackageName() + "/" 
    + R.raw.ingress); //do not add any extension
    //if your file is named sherif.mp4 and placed in /raw
    //use R.raw.sherif
    videoHolder.setVideoURI(video);
    setContentView(videoHolder);

    videoHolder.start();
    videoHolder.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

        @Override
        public void onCompletion(MediaPlayer mp) {

                        mp.start();
        }
    });
}


@Override
protected void onNewIntent (Intent i){


  if( i.getBooleanExtra("finish",false) ){
      wl.release();
      keyguard.reenableKeyguard();
      finish();
  }
}


}

解决方案

Do we have a solution here ? I am still looking for solution, my code as below..

calendar.set(Calendar.DAY_OF_WEEK,getweekday(obj));
    calendar.set(Calendar.HOUR_OF_DAY,timepicker.getCurrentHour());
    calendar.set(Calendar.MINUTE, timepicker.getCurrentMinute());
    calendar.set(Calendar.SECOND, 0);
    calendar.set(Calendar.MILLISECOND, 0);
    if(calendar.before(cal_now)){//if its in the past increment
        calendar.add(Calendar.DATE,1);
    }

PendingIntent sender = PendingIntent.getBroadcast(getApplicationContext(),_id, intent, PendingIntent.FLAG_UPDATE_CURRENT);

    AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY * 7, sender);
