Android:如何取消位置更新请求有意图吗?

我正在尝试禁用我之前在其他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.

I am trying to disable a pending intent(broadcast) which I have previously created in a different activity but I can't get it to work. I've read that I should recreate the intent(with the same extras and everything), pass it as a parameter so that I can instantiate the pendingIntent and then pass the pendingIntent as a parameter to the location managers removeUpdates method.

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

这不起作用，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意图不同.

That didn't work so I thought that it might have to do with the intent that im passing in being a new object and not the same with the one used in order to create the pending intent.

所以我尝试在创建它后立即删除pendingIntent，但也没有用:

So I tried removing the pendingIntent right after I create it but that didnt work either:

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);

推荐答案

通过重新创建 Intent 然后在待处理的 Intent 上调用 .cancel() 来解决它...

Resolved it by recreating the intent and then calling .cancel() on the pending intent...
