Android 无法删除接近警报

用户有一个开关来激活或停用接近警报

当用户激活此开关时，接近警报将以通知方式显示。通过操作栏上的此通知，如果用户将开关更改为“停用”模式，通知将消失。它工作正常

但我的问题是：

我激活了警报，但那一刻它没有显示任何内容，因为我没有接近POI。我改变了主意，现在，我不想要任何警报，所以我将开关更改为“停用”模式（操作栏上出现了任何通知）

但是，当开关打开“停用”模式时，当我接近POI时，警报将出现在操作栏上，我不知道为什么。 我正在使用removeProximityAlert和每个POI的挂起意图的值

激活警报：

public void activateAlerts() {

    Database db = new Database(getApplicationContext());
    Cursor cursor = db.getPois();

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);


    while (cursor.moveToNext()) {

        ...
        Intent intent = new Intent(PROX_ALERT_INTENT);

        String idSubstring = id.substring(7);
        int lastDigitsOfID = Integer.parseInt(idSubstring);
        PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), lastDigitsOfID, intent, PendingIntent.FLAG_ONE_SHOT);

        try {
            locationManager.addProximityAlert(latitude, longitude, Utils.RADIOALERTS, -1, pi);
        } catch (Exception e) {
            Log.e(getClass().getSimpleName().toString(), e.toString());
        }
        notifications.add(new NotificationObject(cursor.getString(idIndex), lastDigitsOfID));
    }
    db.addNotifications(notifications);
}

public void deactivateAlerts() {

    Database db = new Database(getApplicationContext());
    Cursor cursor = db.getIdPendingIntents();

    int idPendingIntentIndex = cursor.getColumnIndex("id_pendingintent");
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    while (cursor.moveToNext()) {
        Intent intent = new Intent(PROX_ALERT_INTENT); 
        PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),
                cursor.getInt(idPendingIntentIndex), intent, 0);
        locationManager.removeProximityAlert(pendingIntent);
    }

    NotificationManager notificationManager =
            (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.cancelAll();
}

PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), lastDigitsOfID, intent, PendingIntent.FLAG_ONE_SHOT);

PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),cursor.getInt(idPendingIntentIndex), intent, 0);

要停用警报：

public void activateAlerts() {

    Database db = new Database(getApplicationContext());
    Cursor cursor = db.getPois();

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);


    while (cursor.moveToNext()) {

        ...
        Intent intent = new Intent(PROX_ALERT_INTENT);

        String idSubstring = id.substring(7);
        int lastDigitsOfID = Integer.parseInt(idSubstring);
        PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), lastDigitsOfID, intent, PendingIntent.FLAG_ONE_SHOT);

        try {
            locationManager.addProximityAlert(latitude, longitude, Utils.RADIOALERTS, -1, pi);
        } catch (Exception e) {
            Log.e(getClass().getSimpleName().toString(), e.toString());
        }
        notifications.add(new NotificationObject(cursor.getString(idIndex), lastDigitsOfID));
    }
    db.addNotifications(notifications);
}

public void deactivateAlerts() {

    Database db = new Database(getApplicationContext());
    Cursor cursor = db.getIdPendingIntents();

    int idPendingIntentIndex = cursor.getColumnIndex("id_pendingintent");
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    while (cursor.moveToNext()) {
        Intent intent = new Intent(PROX_ALERT_INTENT); 
        PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),
                cursor.getInt(idPendingIntentIndex), intent, 0);
        locationManager.removeProximityAlert(pendingIntent);
    }

    NotificationManager notificationManager =
            (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.cancelAll();
}

PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), lastDigitsOfID, intent, PendingIntent.FLAG_ONE_SHOT);

PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),cursor.getInt(idPendingIntentIndex), intent, 0);

我读过以下帖子：

这真的是一样的吗

激活：

public void activateAlerts() {

    Database db = new Database(getApplicationContext());
    Cursor cursor = db.getPois();

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);


    while (cursor.moveToNext()) {

        ...
        Intent intent = new Intent(PROX_ALERT_INTENT);

        String idSubstring = id.substring(7);
        int lastDigitsOfID = Integer.parseInt(idSubstring);
        PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), lastDigitsOfID, intent, PendingIntent.FLAG_ONE_SHOT);

        try {
            locationManager.addProximityAlert(latitude, longitude, Utils.RADIOALERTS, -1, pi);
        } catch (Exception e) {
            Log.e(getClass().getSimpleName().toString(), e.toString());
        }
        notifications.add(new NotificationObject(cursor.getString(idIndex), lastDigitsOfID));
    }
    db.addNotifications(notifications);
}

public void deactivateAlerts() {

    Database db = new Database(getApplicationContext());
    Cursor cursor = db.getIdPendingIntents();

    int idPendingIntentIndex = cursor.getColumnIndex("id_pendingintent");
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    while (cursor.moveToNext()) {
        Intent intent = new Intent(PROX_ALERT_INTENT); 
        PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),
                cursor.getInt(idPendingIntentIndex), intent, 0);
        locationManager.removeProximityAlert(pendingIntent);
    }

    NotificationManager notificationManager =
            (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.cancelAll();
}

PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), lastDigitsOfID, intent, PendingIntent.FLAG_ONE_SHOT);

PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),cursor.getInt(idPendingIntentIndex), intent, 0);

停用：

public void activateAlerts() {

    Database db = new Database(getApplicationContext());
    Cursor cursor = db.getPois();

    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);


    while (cursor.moveToNext()) {

        ...
        Intent intent = new Intent(PROX_ALERT_INTENT);

        String idSubstring = id.substring(7);
        int lastDigitsOfID = Integer.parseInt(idSubstring);
        PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), lastDigitsOfID, intent, PendingIntent.FLAG_ONE_SHOT);

        try {
            locationManager.addProximityAlert(latitude, longitude, Utils.RADIOALERTS, -1, pi);
        } catch (Exception e) {
            Log.e(getClass().getSimpleName().toString(), e.toString());
        }
        notifications.add(new NotificationObject(cursor.getString(idIndex), lastDigitsOfID));
    }
    db.addNotifications(notifications);
}

public void deactivateAlerts() {

    Database db = new Database(getApplicationContext());
    Cursor cursor = db.getIdPendingIntents();

    int idPendingIntentIndex = cursor.getColumnIndex("id_pendingintent");
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    while (cursor.moveToNext()) {
        Intent intent = new Intent(PROX_ALERT_INTENT); 
        PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),
                cursor.getInt(idPendingIntentIndex), intent, 0);
        locationManager.removeProximityAlert(pendingIntent);
    }

    NotificationManager notificationManager =
            (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.cancelAll();
}

PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), lastDigitsOfID, intent, PendingIntent.FLAG_ONE_SHOT);

PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(),cursor.getInt(idPendingIntentIndex), intent, 0);

请检查此方法，并确保您的意图与此处描述的标准一致。

您的问题在于使用

pendingent.FLAG_ONE_SHOT

。这并没有很好的文档记录，但如果删除该标志，它应该可以工作

当您使用

标记一次拍摄创建一个
pendingent
时，Android不会跟踪这个
pendingent
（因为它只允许使用一次）。在我看来，这是一个“优化”，实际上是一个Android bug：-(

当您调用
removeProximityAlert（）
并将
PendingEvent
传递给它时，该方法中的代码会尝试取消所有具有匹配的
PendingEvent
的邻近警报。由于Android不跟踪使用
标志创建的
PendingEvent
，因此“匹配”代码永远找不到您的接近警报，因此不会取消它。
是的，它是相同的值…我将该值存储在本地数据库（激活），然后加载每个POI（停用光标）的值。我已使用日志检查了它，是的，它具有相同的值。我已使用该方法测试代码，它返回“true”出于意图…它们是相同的=（让我知道这是否解决了您的问题，我将添加更多的解释。我现在无法这样做。我正在测试，而不是PendingEvent.FLAG_一次，值为0。从工作办公室看，它似乎可以正常工作（一会儿我将在实际情况下测试它），但是，你能解释一下为什么FLAG_ONE_SHOT不能正确工作吗？我不知道=（在我的回答中添加了一个解释。这是一个Android bug IMHO。请参见问题的不同之处，
FLAG_ONE_SHOT
的行为也会导致这种情况下的混乱。
