整合Mopub廣告到Cocos2dx 2.1

Question

的Mopub集成說明建議用這樣的片段在XML中創建廣告視圖

moPubView = (MoPubView)findViewById(R.id.adview); 
moPubView.setAdUnitId("123412341234"); 
moPubView.loadAd(); 

不幸的是moPubView未被創建，因爲Cocos2dx 2.1不再使用XML進行佈局。因此，由於空指針異常，應用程序在啓動時崩潰。

在嘗試創建廣告視圖之前，我嘗試通過R.layout.main至setContentView。這確實成功創建了廣告視圖，但其他應用程序不可見。

如何在不使用XML的情況下以編程方式創建類似上面的視圖？

我認爲這解決了空指針異常問題，而無需致電setContentView。

private static BannerAdManager m_adDelegate = null; 
private static FrameLayout.LayoutParams m_bannerParam = null; 
private static FrameLayout m_appLayout = null; 


public static void initialize(Activity p_activity) 
{ 
    // create instance of delegate 
    if(m_adDelegate == null) 
    { 
     m_adDelegate = new BannerAdManager(); 
    } 

    m_activity = p_activity; 


    //~~~setup mopub banner ad 
    //~~~create mopub ad view 
    m_mopubView = new MoPubView(m_activity); 

    m_bannerParam = new FrameLayout.LayoutParams( 
         FrameLayout.LayoutParams.WRAP_CONTENT, 
         FrameLayout.LayoutParams.WRAP_CONTENT 
        ); 

    m_mopubView.setAdUnitId(Config_Android._ID); 
    m_mopubView.setBannerAdListener(m_adDelegate); 
    m_mopubView.loadAd(); 

    //get current layout 
    m_appLayout = (FrameLayout) m_activity.findViewById(android.R.id.content); 

    // set default alignment 
    m_bannerParam.gravity = Gravity.TOP | Gravity.CENTER; 

    //add mopub view to layout 
    m_appLayout.addView(m_mopubView, m_bannerParam); 

} 

    public static void setBannerPositionTopWithPadding(float p_padding) 
    { 
     getActivity().runOnUiThread(new Runnable() 
     { 
      public void run() 
      { 
       activity = getActivity(); 

       m_bannerParam.gravity = Gravity.TOP | Gravity.CENTER; 
       m_bannerParam.width = FrameLayout.LayoutParams.WRAP_CONTENT; 
       m_bannerParam.height = FrameLayout.LayoutParams.WRAP_CONTENT; 

       m_bannerParam.topMargin = (int) p_padding; 

       m_appLayout.updateViewLayout(m_mopubView, m_bannerParam); 
       m_mopubView.refreshDrawableState(); 

      } 
     }); 
    }
