How to get text out of Website into String

How can I get Text out of an URL from a website into a TextView or a String in Android/Java.

<html>
<body>
<div class="text" id="editorText" itemprop="text">I want to get this Text</div>
<body>
<html>

"I want to get this Text" into a String:

String TextFromWebsiteHere

EDIT:

Exception after attempting the answer on Jsoup below:

You can use jsoup library for your purpose; a simple example to read paragraphs from the rendered HTML on the website below:

 try {
            Document doc = Jsoup.connect("http://popofibo.com/pop/swaying-views-of-our-past/").get();
            Elements paragraphs = doc.select("p");
            for(Element p : paragraphs) {
              System.out.println(p.text());
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

Output:

It is indeed difficult to argue over the mainstream ideas of evolution of human civilizations...

EDIT:

To demo with you HTML as a static content, you can easily use the id of your div tag:

public static void main(String... args) {
        Document doc = Jsoup
                .parse("<html><body><div class=\"text\" id=\"editorText\" itemprop=\"text\">I want to get this Text</div></body></html>");
        Elements divs = doc.select("div#editorText");
        for (Element d : divs) {
            System.out.println(d.text());
        }
    }

Output:

I want to get this Text

What about this solution (without using an external library):

public static String getContentFromHtmlPage(String page) {
    StringBuilder sb = new StringBuilder();

    try {
        URLConnection connection = new URL(page).openConnection();
        BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String line;
        while ((line = in.readLine()) != null) {
            sb.append(line);
        }
        in.close();
    } catch (IOException e) {
        // handle exception
    }

    return Html.fromHtml(sb.toString()).toString();
}

Use this:

String simpleString = Html.fromHtml("your_html_string").toString();

It will eradicate all the html stuff and will return the content in simple string.

Moreover, if you want to differentiate among different tags/classes and would need a specific text out of html then you may need to use some sophisticated solutions like JSOUP.
