    <p>hello i'm using this example <a href="http://lexandera.com/2009/01/extracting-html-from-a-webview/" rel="nofollow">http://lexandera.com/2009/01/extracting-html-from-a-webview/</a> to get the HTML from a webview. But i need to use it in my superclass and i dont know how to do this. I just can see the html on a AlertDialog but i cant use it. How can I return it to my main class as String?</p> <pre><code>final Context myApp = this; /* An instance of this class will be registered as a JavaScript interface */ class MyJavaScriptInterface { @SuppressWarnings("unused") public void showHTML(String html) { new AlertDialog.Builder(myApp) .setTitle("HTML") .setMessage(html) .setPositiveButton(android.R.string.ok, null) .setCancelable(false) .create() .show(); } } final WebView browser = (WebView)findViewById(R.id.browser); /* JavaScript must be enabled if you want it to work, obviously */ browser.getSettings().setJavaScriptEnabled(true); /* Register a new JavaScript interface called HTMLOUT */ browser.addJavascriptInterface(new MyJavaScriptInterface(), "HTMLOUT"); /* WebViewClient must be set BEFORE calling loadUrl! */ browser.setWebViewClient(new WebViewClient() { @Override public void onPageFinished(WebView view, String url) { /* This call inject JavaScript into the page which just finished loading. */ browser.loadUrl("javascript:window.HTMLOUT.showHTML('&lt;head&gt;'+document.getElementsByTagName('html')[0].innerHTML+'&lt;/head&gt;');"); } }); /* load a web page */ browser.loadUrl("http://lexandera.com/files/jsexamples/gethtml.html"); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
