Intent intent = new Intent(TFNoticeTicketReceiver.ACTION_NOTICE);

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent,0);

Calendar calendar = Calendar.getInstance();

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 10*1000, pendingIntent);

//取消闹钟按钮事件监听
final Button cancelAlarmBtn = (Button)findViewById(R.id.cancelAlarmBtn);
cancelAlarmBtn.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
Intent intent = new Intent(Alarm.this,AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(Alarm.this, 0, intent, 0);
//获取闹钟管理器
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
Toast.makeText(Alarm.this, "闹钟已经取消！", Toast.LENGTH_SHORT).show();
}
});
