你可以通过这个项目在我的github 上找到该项目，你可以设置很多警报，并且可以捕获已取消的警报。
需要持有告警类才能获取具体数据
Alarm.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);
}
}
