Android中WebView加载页面出现白屏解决方案

首先在WebViewClient中添加

@Override    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {        // 不要使用super，否则有些手机访问不了，因为包含了一条 handler.cancel()        // super.onReceivedSslError(view, handler, error);        // 接受所有网站的证书，忽略SSL错误，执行访问网页        handler.PRoceed();    }
其次注意对WebSettings授权
        webSettings.setjavaScriptEnabled(true);        webSettings.setJavascriptCanOpenWindowsAutomatically(true);        webSettings.setCacheMode(WebSettings.LOAD_NO_CACHE);        webSettings.setDomStorageEnabled(true);        webSettings.setDatabaseEnabled(true);        webSettings.setAppCacheEnabled(true);        webSettings.setAllowFileaccess(true);        webSettings.setSavePassWord(true);        webSettings.setSupportZoom(true);        webSettings.setBuiltInZoomControls(true);        webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);        webSettings.setUseWideViewPort(true);
