Android webview加载html自适应屏幕

webView.getSettings().setJavaScriptEnabled(true);webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);// 不使用缓存webView.getSettings().setUserAgentString(System.getProperty("http.agent"));webView.getSettings().setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);//把html中的内容放大webview等宽的一列中webView.getSettings().setAppCacheEnabled(true);webView.getSettings().setDomStorageEnabled(true);webView.setWebViewClient(new MyWebViewClient());webView.loadData(productDiscribeInfo, "text/html", "UTF-8");

private class MyWebViewClient extends WebViewClient {    @Override    public void onPageFinished(WebView view, String url) {        super.onPageFinished(view, url);        imgReset();//重置webview中img标签的图片大小    }    @Override    public boolean shouldOverrideUrlLoading(WebView view, String url) {        view.loadUrl(url);        return true;    }}

/** * 对图片进行重置大小，宽度就是手机屏幕宽度，高度根据宽度比便自动缩放 **/private void imgReset() {    webView.loadUrl("javascript:(function(){" +            "var objs = document.getElementsByTagName('img'); " +            "for(var i=0;i<objs.length;i++)  " +            "{"            + "var img = objs[i];   " +            "    img.style.maxWidth = '100%'; img.style.height = 'auto';  " +            "}" +            "})()");}
