Android:如何取消位置更新請求有意圖嗎?

我正在嘗試禁用我之前在其他活動中創建的待處理意圖(廣播)，但我無法讓它工作.我讀過我應該重新創建意圖(具有相同的附加功能和所有內容)，將其作為參數傳遞，以便我可以實例化pendingIntent，然后將pendingIntent 作為參數傳遞給位置管理器的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.

換句話說:

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

這不起作用，所以我認為這可能與我作為新對象傳入的意圖有關，而與用于創建待處理意圖的意圖不同.

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.

所以我嘗試在創建它后立即刪除pendingIntent，但也沒有用:

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);

推薦答案

通過重新創建 Intent 然后在待處理的 Intent 上調用 .cancel() 來解決它...

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