android webview渲染显示白页

有时,当我使用loadUrl加载Web视图时,直到我触摸屏幕或滚动浏览,网站才会显示出来.

就像我有一个webview绘图问题.

            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("http://" + 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");
                }


            });

有人知道我为什么会有这种问题吗？

解决方法:

您正在测试哪个版本的Android？ Android的4.1之前版本有时似乎在WebViews中存在此类问题.

将此添加到该活动的清单以解决问题：

android:hardwareAccelerated="false"
