Android webview啓動畫面不會消失

Question

我在這裏回答了關於在webview上放置啓動畫面的答案，我知道它現在出現在我的應用程序中，但現在它不像它應該的那樣是陰暗的。當我註釋出啓動畫面時，該網站加載得很好。

java文件 - onCreate是我認爲的興趣點。

     mWebView = (WebView) findViewById(R.id.activity_main_webview); 
     imgLoading = (ImageView)findViewById(R.id.imgloader);

     webSettings.setJavaScriptEnabled(true); 

     // Force links and redirects to open in the WebView instead of in a browser 
     mWebView.setWebViewClient(new WebViewClient() { 

      @Override

      // super.onPageFinished(view, url); commented out not fix 
       //hide loading image 
       imgLoading.setVisibility(View.GONE); 
       bar.setVisibility(View.GONE);
