有时候，当我打开我的WebView与使用loadURL，该网站没有显示出来，直到我触摸屏幕或滚动。

Sometimes, when I load my webview with loadUrl, the website is not showing up until I touch the screen or scroll.

这就像我有一个web视图绘制的问题。

It's like I have a webview drawing problem.

Context context = ctx; final Dialog dialog = new Dialog(context); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.setContentView(R.layout.website); WebView webView = (WebView) dialog.findViewById(R.id.weburl); webView.setScrollbarFadingEnabled(false); //Disable the horizontal scroll bar webView.setHorizontalScrollBarEnabled(false); //Enable JavaScript webView.getSettings().setJavaScriptEnabled(true); //Set the user agent webView.getSettings().setUserAgentString("AndroidWebView"); //Clear the cache webView.clearCache(true); webView.loadUrl("" + WebUrl); webView.setWebViewClient(new WebViewClient() { public boolean shouldOverrideUrlLoading(WebView view, String url){ // do your handling codes here, which url is the requested url // probably you need to open that url rather than redirect: view.loadUrl(url); view.setVisibility(View.VISIBLE); return false; // then it is not handled by default action } @Override public void onPageFinished(WebView view, String url) { view.refreshDrawableState(); Log.v("FINISH","FINISH"); } });

不要任何人有一个想法，为什么我有这样的问题。

Do anybody have an idea why I have this kind of problem.
