你可以通过这个项目在我的github上找到这个项目，你可以设置很多警报，并且可以捕获已取消的警报。
需要保持警报类才能获取特定数据
报警器.java
public class Alarm {
public int getState() {
return state;
}
public void setState(int state) {
this.state = state;
}
public int getUniqueID() {
return uniqueID;
}
public void setUniqueID(int uniqueID) {
this.uniqueID = uniqueID;
}
private int state;
private int uniqueID;
}
AlarmHolder 是单例的，并将警报保存在数组列表中
AlarmHolder.java
import java.util.ArrayList;
public class AlarmHolder{
private static AlarmHolder uniqueAlarmHolder;
private ArrayList<Alarm> lAlarms;
private AlarmHolder() {
lAlarms = new ArrayList<Alarm>();
}
public synchronized static AlarmHolder getInstance()
{
if (uniqueAlarmHolder == null) {
uniqueAlarmHolder = new AlarmHolder();
}
return uniqueAlarmHolder;
}
public void registerAlarm(int id) {
Alarm a = new Alarm();
a.setState(1);
a.setUniqueID(id);
lAlarms.add(a);
}
public void removeAlarm(int id,Alarm a) {
Alarm newAlarm = new Alarm();
a.setState(0);
a.setUniqueID(id);
lAlarms.remove(id);
lAlarms.add(newAlarm);
}
public void replaceList(ArrayList<Alarm> newList) {
lAlarms.clear();
lAlarms.addAll(newList);
}
public ArrayList<Alarm> getAlarms() {
return lAlarms;
}
public Alarm lastAlarmId() {
return lAlarms.get(lAlarms.size()-1);
}
}

// with this key we can catch the alarm which we want
int key = intent.getIntExtra("key",0);
for (Alarm alarm : objAlarmHolder.getAlarms()) {
// if alarmstate is 1 and the key belogs that alarm device will vibrate
if (alarm.getState() == 1 & alarm.getUniqueID() == key ) {
Log.v("alarm", String.valueOf(String.valueOf(alarm.getUniqueID())));
Toast.makeText(context, "your alarm id : " + String.valueOf(alarm.getUniqueID()),Toast.LENGTH_LONG).show();
Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
vibrator.vibrate(2000);
} else {

}
}
}
}
