如何创建多个报警？ [英] How can create more than one alarm?

问题描述

我能够创建和取消与下面的code报警。 我想创建多个报警。报警时间来自一个ArrayList。在此ArrayList，我想为每一个日期报警。而$ P $取消按钮的psses将只取消当前报警。我该怎么办呢？

 公共无效的onCreate（包savedInstanceState）{
    super.onCreate（savedInstanceState）;
    的setContentView（R.layout.main）;
    AlarmManager alarmManager =（AlarmManager）getSystemService（Context.ALARM_SERVICE）;
    setOneTimeAlarm（）;

    buttonCancel.setOnClickListener（新Button.OnClickListener（）{
        @覆盖
        公共无效的onClick（查看为arg0）{
            AlarmManager alarmManager =（AlarmManager）getSystemService（ALARM_SERVICE）;
            alarmManager.cancel（pendingIntent）;

            //告诉我们所做的用户。
            Toast.makeText（MainActivity.this！取消，Toast.LENGTH_LONG）.show（）;
        }
    }）;
}

私人无效setOneTimeAlarm（）{
    意向意图=新的意图（这一点，AReceiver.class）;
    pendingIntent = PendingIntent.getBroadcast（此，0，意向，PendingIntent.FLAG_ONE_SHOT）;
    alarmManager.set（AlarmManager.RTC_WAKEUP，calendar.getTimeInMillis（），pendingIntent）;
}
 

解决方案

我会后有一种方法，我在我所创建的应用程序之一，做了一个例子。

在打电话报警，你需要发送一个额外的ID是这样的： TMP是一个对象，它具有一个唯一的ID。

 意向意图=新的意图（DisplayActivity.this，AlarmReciever.class）;

intent.setData（Uri.parse（计时器：+ tmp.getId（）））;

PendingIntent pendingIntent = PendingIntent.getBroadcast（DisplayActivity.this，1，意向，0）;
AlarmManager AM =（AlarmManager）getSystemService（ALARM_SERVICE）;
am.set（AlarmManager.RTC_WAKEUP，calendar.getTimeInMillis（），pendingIntent）;
 

然后检索与该行的ID：

 的Long.parseLong（intent.getData（）。getSchemeSpecificPart（））
 

在取消刚刚创建相同的悬而未决的意图与ID和呼叫alarmmanager.cancel（）

编辑：

要取消对用户点击（这里是tmp.getId就派上用场了），我只是用这个code，我想你需要创建相同pendingIntent才能够取消该项目的具体报警具体的报警。

 意向意图=新的意图（DisplayActivity.this，AlarmReciever.class）;
 intent.setData（Uri.parse（计时器：+ tmp.getId（）））;
 PendingIntent pendingIntent = PendingIntent.getBroadcast（DisplayActivity.this，1，意向，0）;
 AlarmManager AM =（AlarmManager）getSystemService（ALARM_SERVICE）;
 am.cancel（pendingIntent）;
 

AlarmReciever是我的BroadcastReceiver。 DisplayActivity是活动本身。

这是在AlarmReciever我有以下的code：

 的Long.parseLong（intent.getData（）。getSchemeSpecificPart（））
 

I am able to create and cancel an alarm with the code below. I want to create more than one alarm. Alarm times comes from an arraylist. In this arraylist I would like to create an alarm for each date. And presses of the cancel button will cancel only the current alarm. How can I do it?

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    setOneTimeAlarm(); 

    buttonCancel.setOnClickListener(new Button.OnClickListener() {
        @Override
        public void onClick(View arg0) {
            AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
            alarmManager.cancel(pendingIntent);

            // Tell the user about what we did.
            Toast.makeText(MainActivity.this, "Cancel!", Toast.LENGTH_LONG).show();
        }
    });
}

private void setOneTimeAlarm() {
    Intent intent = new Intent(this, AReceiver.class);
    pendingIntent = PendingIntent.getBroadcast(this, 0, intent, PendingIntent.FLAG_ONE_SHOT);
    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);
}

解决方案

I'll post an example with a way I did it in one of the apps I created.

When calling the alarm you need to send an extra id like this: Tmp is an object which has a unique ID.

Intent intent = new Intent(DisplayActivity.this,AlarmReciever.class);

intent.setData(Uri.parse("timer:"+tmp.getId()));

PendingIntent pendingIntent = PendingIntent.getBroadcast(DisplayActivity.this,1, intent, 0);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis(),pendingIntent);

and then you retrieve the id with this line:

Long.parseLong(intent.getData().getSchemeSpecificPart())

When cancelling just create the same pending intent with the ID and call alarmmanager.cancel()

Edit:

To cancel the specific alarm on the item the user clicked on (here is where tmp.getId comes in handy) I just used this code, I think you need to create the same pendingIntent to be able to cancel the specific alarm.

 Intent intent = new Intent(DisplayActivity.this,AlarmReciever.class);
 intent.setData(Uri.parse("timer:"+tmp.getId()));
 PendingIntent pendingIntent = PendingIntent.getBroadcast(DisplayActivity.this,1, intent, 0);
 AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
 am.cancel(pendingIntent);

AlarmReciever is my BroadcastReceiver. DisplayActivity is the activity itself.

It's in AlarmReciever I have the following code:

Long.parseLong(intent.getData().getSchemeSpecificPart())
