取消报警管理器中的报警？

Question

当用户输入日期和时间时，将其放入警报管理器

public Manager(Context context){
       mContext = context;
       tolarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
       }

public void setSilent(Long id, Calendar when){

     Intent go = new Intent(mContext, someclass.class);
     PendingIntent golow = PendingIntent.getBroadcast(mContext, 0 , i, PendingIntent.FLAG_ONE_SHOT);
    toAlarmManager.set(AlarmManager.RTC_WAKEUP, when.getTimeInMillis(), golow);

当设置闹钟时，如果我不再需要闹钟，如何将其从闹钟中删除？

Answer 1

int RC = alarmRequestCode; // your request code is 0
Intent intentAlarm = new Intent(context, AlarmReciever.class);
PendingIntent sender = PendingIntent.getBroadcast(context, RC, intentAlarm, 0);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);
alarmManager.cancel(sender);

Answer 2

你做

toAlarmManager.cancel(golow);

删除任何具有匹配意图的警报。
