Question

我正在通过服务添加警报，我还创建一个广播来取消所有警报（Pending Intents）在同一服务中当我按下注销时我想取消注册所有警报，所以即时通讯呼叫广播接收器，但仍然是警报仍在开火。我还尝试将待处理的Intent对象存储到数组列表中并执行相同的操作。然后删除闹钟的同一个对象，这是我的代码..

public class AddReminderService extends Service {
    ArrayList<Integer> intentArray;
    ArrayList<pendingIntent> pendingIntentArray;
    AlarmManager alarmManager,CancelalarmManager;
    ArrayList<Bundle> bundleArray;
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
    @Override
    public void onCreate() {
        super.onCreate();
        registerReceiver(cancelAlarms, new IntentFilter("com.x.y.ReminderAlerts.AlarmCancel"));
    }
    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        if (intent.hasExtra("ReminderDetails")) {
            @SuppressWarnings("unchecked")
            ArrayList<HashMap<String, String>> entries = (ArrayList<HashMap<String, String>>) intent
                    .getSerializableExtra("ReminderDetails");
            Log.v("AddReminderService", "OnStart entries size()"+entries.size());
            addReminder(entries);
        }
    }

    private void addReminder(ArrayList<HashMap<String, String>> entries) 
    {
        intentArray= new ArrayList<Integer>();
        bundleArray= new ArrayList<Bundle>();
        pendingIntentArray= new ArrayList<pendingIntent>();
        for (int i = 0; i < entries.size(); i++) {
            alarmManager = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
            setAlarm(i,alarmTime, activity, stringStartTime, stringEndTime, ReminderSysID);
        }
    }

    private void setAlarm(int position,long alarmTime, String actvity, String startTime,
        String endTime, String ReminderSysID) {
        if (alarmTime > (new Date()).getTime()) {
            Intent intent = new Intent(getApplicationContext(), AlarmReceiver.class);
            intent.setAction("com.x.y.ReminderAlerts.ALARMRECIEVER");
            intent.addCategory("com.x.y.ReminderAlerts.ALARMRECIEVER");
            Bundle c = new Bundle();
            c.putString("Actvity", actvity);
            c.putString("Start_tim", startTime);
            c.putString("Endtime", ReminderSysID);
            c.putInt("ReminderSysID", Integer.parseInt(ReminderSysID));
            intent.putExtras(c);
            bundleArray.add(c);
            PendingIntent pendingIntent = PendingIntent.getService(
                getApplicationContext(), Integer.parseInt(ReminderSysID), intent,PendingIntent.FLAG_ONE_SHOT);
            pendingIntentArray.add(pendingIntent);
            intentArray.add(Integer.parseInt(ReminderSysID));       
            Log.i("intentArray alarm id",Integer.parseInt(ReminderSysID)+"" );
            Log.e("registerReciever",""+pendingIntent); 
            alarmManager.set(AlarmManager.RTC_WAKEUP, alarmTime, pendingIntent);
        }
    }
    public BroadcastReceiver cancelAlarms = new BroadcastReceiver() {   
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.e("cancelalarmreciever","On alarm cancel reciever");
            if(intentArray.size()>0){
                for(int i=0; i<intentArray.size(); i++){
                    Log.i("cancelAlarms alarm id",intentArray.get(i)+"" );
                    Intent tempIntent = new Intent(getApplicationContext(), AlarmReceiver.class);
                    intent.setAction("com.x.y.ReminderAlerts.ALARMRECIEVER");
                    intent.addCategory("com.x.y.ReminderAlerts.ALARMRECIEVER");
                    intent.putExtras(bundleArray.get(i));
                    PendingIntent pendingIntent = PendingIntent.getService(
                        getApplicationContext(), intentArray.get(i), tempIntent,PendingIntent.FLAG_UPDATE_CURRENT);
                    Log.v("registerReciever",""+pendingIntent);
                ///.cancel();
                    Log.v("cancelalarmreciever index","On alarm cancel reciever"+intentArray.get(i));
                    CancelalarmManager = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
                    CancelalarmManager.cancel(pendingIntent);

            }
            intentArray.clear();
            pendingIntentArray.clear();
            unregisterReceiver(cancelAlarms);
            stopSelf();
        }   
    };

Answer 1

你的代码需要很多爱： - （

无论如何，当您尝试取消onReceive()中的闹钟时，请执行以下操作：

Intent tempIntent = new Intent(getApplicationContext(), AlarmReceiver.class);
intent.setAction("com.x.y.ReminderAlerts.ALARMRECIEVER");
intent.addCategory("com.x.y.ReminderAlerts.ALARMRECIEVER");
intent.putExtras(bundleArray.get(i));

你可能意味着在tempIntent上设置ACTION，CATEGORY和extras，如下所示：

Intent tempIntent = new Intent(getApplicationContext(), AlarmReceiver.class);
tempIntent .setAction("com.x.y.ReminderAlerts.ALARMRECIEVER");
tempIntent .addCategory("com.x.y.ReminderAlerts.ALARMRECIEVER");
tempIntent .putExtras(bundleArray.get(i));

Answer 2

代码中有点错误。不要尝试使用相同的对象。创造一个不同的对象。

取消在android中的警报管理器中设置的所有待处理Intent，但不起作用
