Iframe not loading in webview android

问题:

I have a webview. Everything is working fine but when I am opening a page which has iframe, the iframe is not getting visible. Are there any specific settings required?

回答1:

First add Hardware Acceleration and add the following lines to your webView

webView.setWebChromeClient(new WebChromeClient());

EDIT 1

It will be hard to identify the problem but try adding WebChromeClient, WebViewClient and also don't forget to enable javascript before loading URL like this

webView= (WebView) findViewById(R.id.webview); 
webView.setWebChromeClient(new WebChromeClient()); 
webView.setWebViewClient(new WebViewClient()); 
webView.getSettings().setJavaScriptEnabled(true);

EDIT 2

If you really need to load content of iframe then Try using Jsoup to load html page but you have to find the iframe and fetch the content manually.

Document doc=...
Element iframe1 = doc.select("#iframe1").first();

if (iframe1!=null) {
   Document iframeContent = Jsoup.connect(iframe1.attr("src")).get();

  }

where iframe1 is id of your iframe.

Can you check if you have

android:hardwareAccelerated="true"

in your AndroidManifest file, in the <application> tag of that activity.

following hack worked for me for loading iframes in webview.Hope some one still might find it useful

 String webContent="your data to be loaded in webview";

if(webContent.contains("iframe")){
                Matcher matcher = Pattern.compile("src=\"([^\"]+)\"").matcher(webContent);
                matcher.find();
                String src = matcher.group(1);
                webContent=src;

            try {
                URL myURL = new URL(src);
                webView.loadUrl(src);

            } catch (MalformedURLException e) {
                e.printStackTrace();
            }
        }else {

            webView.loadDataWithBaseURL(null, "<style>img{display: inline;height: auto;max-width: 100%;}</style>" + webContent, "text/html", "UTF-8", null);}

    }
}

Also do not forget to add Internet permission in your manifest file.

<uses-permission android:name="android.permission.INTERNET" />

This maybe a too late answer! I hope it will help someone.

Just try to set up a desktop user agent to your webview

String DESKTOP_USER_AGENT = "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2049.0 Safari/537.36";
webView.getSettings().setUserAgentString(DESKTOP_USER_AGENT);

If you modify webview configurations and use loadData function to load iframe, some iframes will not work in webview. So for the solution I have implemented AdvancedWebView library.

https://github.com/delight-im/Android-AdvancedWebView

Use loadHtml(URL) method with this webview and you can pass URL in parameter and you will be able to view iframe in webview.
