進度對話框導致「窗口泄漏」

我有一個名爲requestLocation的方法，即啓動一個進度對話框。我從onResume（）調用這個方法;進度對話框導致「窗口泄漏」

我的方法：

public void requestLocation() { 
    try { 
     progressDialog = ProgressDialog.show(this, "", "Obtaining Location Service", true); 
    } 
    catch(Exception e) { 

    } 

    updates=0; 
    startingLocal = null; 
    latestLocal = null; 
    gps = null; 
    gps = new KNLocationService(this); 
    gps.setParent(this); 
    // check if GPS enabled 
    if (gps.canGetLocation()) { 

     double latitude = gps.getLatitude(); 
     double longitude = gps.getLongitude(); 

     //progressDialog.dismiss(); 
     //locationServiceText.setText("Aquiring location"); 

    } else { 
     try { 
      progressDialog.dismiss(); 
     } catch (Exception e) { 

     } 

     locationServiceText.setText("No LocationService Provided"); 
    } 

}

，但我發現了以下錯誤是我假設是因爲進度對話框，但我似乎無法找出到底是什麼原因造成它..

我似乎沒有崩潰的應用程序，但我仍然想改正這一點。

if (gps.canGetLocation()) 
    // Then progress dialog will not be dismissed.

這是造成泄漏。任務完成後關閉對話框。

即使我不想要在那裏解僱它，在gps更新的方法中，我仍然想用不同的消息顯示它？ – erik

@erik。沒問題..只是在所有任務完成時關閉對話框。我相信你不想顯示無窮大的對話框。顯示泄漏是因爲您沒有忽略對話。如果您想在活動生命週期中顯示，請在onPause關閉它 – stinepike

你必須摒棄對話框：

@Override 
protected void onDestroy() { 
    super.onDestroy(); 
    progressDialog.dismiss(); 
}
