可能重复:
Android:如何取消有意图的位置更新请求?

我正在尝试禁用我之前在不同活动中创建的待处理意图(广播),但我无法让它工作。我读过我应该重新创建意图(具有相同的附加功能和所有内容),将其作为参数传递,以便我可以实例化 pendingIntent,然后将pendingIntent 作为参数传递给位置管理器的 removeUpdates 方法。

换句话说:


Bundle extra = new Bundle();

extra.putString("name", extras.getString("poiName")); //create same extras

extra.putInt("id", extras.getInt("rowId")); //create same extras

Intent intent = new Intent(PROX_ALERT_INTENT);  

intent.putExtra(PROX_ALERT_INTENT, extra);  //put same extras in the intent

PendingIntent proximityIntent = PendingIntent.getBroadcast(this.getApplicationContext(),extras.getInt("rowId") , intent, PendingIntent.FLAG_UPDATE_CURRENT);  //pass in the intent

LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
                                               locationManager.removeUpdates(proximityIntent);  //remove pendingIntent

那没有用,所以我认为这可能与我作为新对象传入的意图有关,而与用于创建待处理意图的对象不同。

所以我尝试在创建它之后立即删除pendingIntent,但这也不起作用:

Bundle extras = new Bundle();

    extras.putString("name", poiName);

    extras.putInt("id", requestCode);

    Intent intent = new Intent(PROX_ALERT_INTENT);

    intent.putExtra(PROX_ALERT_INTENT, extras);

    PendingIntent proximityIntent = PendingIntent.getBroadcast(this.getApplicationContext(), requestCode , intent, PendingIntent.FLAG_CANCEL_CURRENT);

    locationManager.addProximityAlert(
        latitude, // the latitude of the central point of the alert region
        longitude, // the longitude of the central point of the alert region
        POINT_RADIUS, // the radius of the central point of the alert region, in meters
        PROX_ALERT_EXPIRATION, // time for this proximity alert, in milliseconds, or -1 to indicate no expiration 
        proximityIntent // will be used to generate an Intent to fire when entry to or exit from the alert region is detected
   );
    locationManager.removeUpdates(proximityIntent);

你能帮我吗???它从星期三开始就一直在窃听……希望我有更多的声誉可以在这个问题上加个界限……

谢谢

通过重新创建意图然后在挂起的意图上调用 .cancel() 来解决它......
