Question

我正在使用不同的ID创建多个警报，假设我创建了警报1,2,3，我只想取消2。你能指导我怎么样？我确实搜索了SO，但我没有发现任何关于是否必须在取消警报时将“相同的额外数据”添加到待处理状态，所以我想我会问你，看看你会怎么做

以下是我创建闹钟的方法

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

    Intent broadcast_intent = new Intent(this, AlarmBroadcastReceiver.class);
    broadcast_intent.putExtra("Tag", Object1);
    broadcast_intent.putExtra("Tag2", Object2);

   for(int i=1;i<=3;i++){       
       PendingIntent pendingIntent = PendingIntent.getBroadcast(this, i,  broadcast_intent, PendingIntent.FLAG_UPDATE_CURRENT);

       alarmManager.set(AlarmManager.RTC_WAKEUP, triggerAtTime, pendingIntent);

   }

如何取消闹钟2？

Answer 1

它为我工作：-----

   buttonCancel.setOnClickListener(new Button.OnClickListener(){

  @Override
 public void onClick(View arg0) {

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
         pendingIntent = PendingIntent.getBroadcast(AndroidAlarmService.this, 0, broadcast_intent ,PendingIntent.FLAG_CANCEL_CURRENT);             
alarmManager.cancel(pendingIntent);

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


 }});

如果我添加了额外的数据，如何取消特定的警报
