After Imagebutton - > Webview Addmob不會啓動

Question

我有一個小問題..我的應用程序以啓動畫面開始，我可以在3個圖像按鈕之間選擇以打開3個不同的Web視圖（3個URL）。在我的初始屏幕中，我從admob獲得了我的「Smart_Banner」，並且在點擊任何圖像按鈕之後，我切換到webview並在此WebView中，admob消失了，它不再回來！我必須重建一個新的admob在那裏做廣告嗎？傢伙，我需要一些真正的幫助！

    if (con_manager.getActiveNetworkInfo() != null 
      && con_manager.getActiveNetworkInfo().isAvailable() 
      && con_manager.getActiveNetworkInfo().isConnected()) { 
     return true; 
    } else { 
     return false;

Answer 1

要調用setContentView(mWebView);與剛剛web視圖替換視圖中的活動。即它會首先刪除AdView（以及其他）。
