我想使用基于某些数据库时间值的警报。目前我的闹钟正在为一个闹钟工作,例如:我在上午 8:30、上午 10:20 和下午 12:20 设置了 3 个闹钟我的闹钟仅适用于一个值。这是我正在创建闹钟的提醒类

public class OwnGoalReminder extends EventReminder {
GoalOwn goalOwn;
int interValTime;
int goalId;
int hour;
int minute;
int requestCode;
String type;

public void setInterValTime(int interValTime) {
this.interValTime = interValTime;
}

public int getHour() {
return hour;
}

public void setHour(int hour) {
this.hour = hour;
}
public void setRequestCode(int requestCode) {
this.requestCode = requestCode;
}
public void setType(String type) {
this.type = type;
}

public int getMinute() {
return minute;
}
@Override
protected int getGoalId(){return this.goalId;}

public void setMinute(int minute) {
this.minute = minute;
}

public OwnGoalReminder(Context context , int goalId, int interValTime){
super(context);
this.interValTime = interValTime;
this.goalId = goalId;
}

@Override
protected String getType() {
return this.type;
}


@Override
protected String getMessage() {
return "Reminder!!! You should check your goals!";
}

@Override
protected int getRequestCode() {
return requestCode;
}

@Override
protected EventTime getEventTime() {
int h = hour;
int m = minute;
return new EventTime(hour,minute,interValTime);
}

@Override
protected Class getBroadcastReceiver() {
return MyBroadcastReceiver.class;
}
}

这是 OwnGOalReminder 的基类

public abstract class EventReminder{
protected Context context;
protected Alarm alarm;
PushNotificationsManager notificationsManager;


public void remind() {
Bundle bundle = new Bundle();
bundle.putString("type", getType());
bundle.putString("msg", getMessage());
notificationsManager.sendNotification(bundle);
}

protected abstract String getType();

protected abstract String getMessage();

protected abstract int getRequestCode();
protected abstract int getGoalId();

protected abstract EventTime getEventTime();

protected abstract Class getBroadcastReceiver();

protected EventReminder(Context context){
this.context = context;
alarm = new Alarm(context, getBroadcastReceiver());
notificationsManager = new PushNotificationsManager(context);
}

public void startReminder(){
alarm.startAlert(getRequestCode(), getGoalId(), getEventTime().hour, getEventTime().minute, getEventTime().intervalInMinute);
//alarm.setAlarm(context, getEventTime().hour, getEventTime().minute);
}


protected class EventTime{
int hour, minute, intervalInMinute;
public EventTime(int hour, int minute, int intervalInMinute){
this.hour = hour;
this.minute = minute;
this.intervalInMinute = intervalInMinute;
}
}
}

这是警报类,我正在创建警报管理器

public class Alarm{

private final Context context;
private Class broadcastReceiver;

public Alarm(Context context, Class broadcastReceiver){
this.context = context;
this.broadcastReceiver = broadcastReceiver;
}

public void startAlert(int requestCode, int gid, int hour, int minute, int intervalMinute) {
Log.d(this.getClass().getName(), "starting alert");
int i = 10;
Long timeToMilliSeconds = timeToMilliSeconds(hour, minute);
Intent intent = new Intent(context, MyBroadcastReceiver.class);
intent.putExtra("reqcode", requestCode);
intent.putExtra("time", timeToMilliSeconds);
intent.putExtra("gid" , gid);

PendingIntent pendingIntent = PendingIntent.getBroadcast(
context, requestCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(ALARM_SERVICE);
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, timeToMilliSeconds+
+ (i * 1000), 1000*60*intervalMinute, pendingIntent);
//Toast.makeText(context, "Alarm set in " + i + " seconds",Toast.LENGTH_LONG).show();
}

@NonNull
public static long timeToMilliSeconds(int hour, int minute) {
Date dat = new Date();//initializes to now
Calendar cal_alarm = Calendar.getInstance();
Calendar cal_now = Calendar.getInstance();
cal_now.setTime(dat);
cal_alarm.setTime(dat);
cal_alarm.set(Calendar.HOUR_OF_DAY,hour);//set the alarm time
cal_alarm.set(Calendar.MINUTE, minute);
cal_alarm.set(Calendar.SECOND,0);

if(cal_alarm.getTimeInMillis() < System.currentTimeMillis()){
cal_alarm.add(Calendar.DAY_OF_YEAR,1);
}
return cal_alarm.getTimeInMillis();
}

}

这是我根据数据库值创建多个警报对象的方法

public static void registerAlarm(Context context){
if(!UserPreferences.isAlarmRegistered(context)) {
GoalReminder goalReminder = new GoalReminder(context);


AppraisalReminder appraisalReminder = new AppraisalReminder(context);
goalReminder.startReminder();
appraisalReminder.startReminder();
// ownGoalReminder.startReminder();
//UserPreferences.setIsAlarmRegistered(context,true);
ArrayList<Goal> LIST_OF_OWN_GOALS = new ArrayList<>();

LIST_OF_OWN_GOALS = (ArrayList<Goal>) Goal.getGoalFromOwnGoals();

for (Goal g : LIST_OF_OWN_GOALS) {
OwnGoalReminder ownGoalReminder = new OwnGoalReminder(context , g.getgId(),3 );
int h = Integer.parseInt(g.getrTime())/60;
int min = Integer.parseInt(g.getrTime())%60;
ownGoalReminder.setHour(h);
ownGoalReminder.setMinute(min);
ownGoalReminder.setRequestCode(16);

ownGoalReminder.setType("16");
ownGoalReminder.startReminder();
LIST_OF_OWN_REMINDERS.add(ownGoalReminder);

}



}
}

这是我的广播接收器类:

public class MyBroadcastReceiver extends BroadcastReceiver {
private static final String[] goalMessagesArray = ApraiseApplication.getContext().getResources().getStringArray(R.array.goals_messages);
private static Queue<String> goalMessagesQueue = new ArrayDeque<>(Arrays.asList(goalMessagesArray));


private static final String[] appraisalsMessagesArray = ApraiseApplication.getContext().getResources().getStringArray(R.array.appraisals_messages);
private static Queue<String> appraisalsMessagesQueue = new ArrayDeque<>(Arrays.asList(appraisalsMessagesArray));

@Override
public void onReceive(Context context, Intent intent) {
Log.d(this.getClass().getName(), "notify");
PushNotificationsManager notificationsManager = new PushNotificationsManager(context);
PowerManager.WakeLock wl = acquireWakeLock(context);

int requestCode = intent.getIntExtra("reqcode",1);
int gId = intent.getIntExtra("gid",1);

long time = intent.getLongExtra("time",0);
String message = "";

// it will create the instance of Random class
Random randomGenerator = new Random();

// it will generate a random number based on goal message arrayList length
int indexForGoalMessage = randomGenerator.nextInt(goalMessagesArray.length);

// it will generate a random number based on appraisalsMessagesArray length
int indexForAppraisalsMessage = randomGenerator.nextInt(goalMessagesArray.length);
String gid = "";


if(isNotifyTimePassed(time)){
//return;
}


if(requestCode == 123){

// if(goalMessagesQueue.isEmpty()){
// goalMessagesQueue = new ArrayDeque<>(Arrays.asList(goalMessagesArray));
// }
// message = goalMessagesQueue.poll();

message = goalMessagesArray[indexForGoalMessage];



}else if(requestCode == 124){

// if(appraisalsMessagesQueue.isEmpty()){
// appraisalsMessagesQueue = new ArrayDeque<>(Arrays.asList(appraisalsMessagesArray));
// }
// message = appraisalsMessagesQueue.poll();

message = appraisalsMessagesArray[indexForAppraisalsMessage];


}

Bundle bundle = new Bundle();
bundle.putString("type", Integer.toString(requestCode));
bundle.putString("msg", message);
bundle.putString("gid" , String.valueOf(gId));
notificationsManager.sendNotification(bundle);

wl.release();
}

@NonNull
private PowerManager.WakeLock acquireWakeLock(Context context) {
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "");
wl.acquire();
return wl;
}

private boolean isNotifyTimePassed(long time) {
return (System.currentTimeMillis()-time) > 1000L*60L*5L;
}

}

最佳答案

[我从谷歌搜索中找到了这个解决方案]

我通过传递依赖于当前时间的唯一 ID 解决了这个问题:-

final int intent_id= (int) System.currentTimeMillis(); 

PendingIntent pendingIntent = PendingIntent.getBroadcast(
context, intent_id , intent, PendingIntent.FLAG_UPDATE_CURRENT);
