加载网址后，Android Web视图出现问题。问题是，仅在触摸屏幕时才显示网络上的图像，一旦加载。有人知道这是什么吗？或我该如何解决？

使用标准浏览器不会出现这种图像显示延迟

   @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_blank,container,false);


    banner=(ImageView) view.findViewById(R.id.imageView10);
    banner.setVisibility(View.VISIBLE);

    webView = (WebView) view.findViewById(R.id.webView);


    webView.getSettings().setDomStorageEnabled(true);

    webView.getSettings().setallowFileaccess(true);
    webView.getSettings().setappCacheEnabled(true);
    webView.getSettings().setJavaScriptEnabled(true);
    webView.setVisibility(View.INVISIBLE);

    progressDialog = new ProgressDialog(this.getactivity());
    progressDialog.setIcon(R.mipmap.ic_launcher);
    progressDialog.setMessage("Cargando...");
    progressDialog.show();

    webView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);

    webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageStarted(WebView view,String url,Bitmap favicon)
            {
                super.onPageStarted(view,url,favicon);
                banner.setVisibility(View.VISIBLE);
                webView.setVisibility(View.INVISIBLE);

                progressDialog.show();

            }

        @Override
            public void onPageFinished(WebView view,String url) {
                super.onPageFinished(view,url);
            view.loadUrl ("javascript:(function() { " + "document.getElementsByClassname('td-header-wrap td-header-style-1 ')[0].style.display='none'; "+ "document.getElementsByClassname('td-fix-index')[0].style.display='none'; " +"} )()");
            banner.setVisibility(View.INVISIBLE);
            webView.setVisibility(View.VISIBLE);

            progressDialog.dismiss();
            }

        });

        webView.loadUrl("http://www......");

        return view;
    }
