  • 0

In android I’m using WebView to display a part of a webpage which I fetched from the internet using HttpClient from Apache. To only have the part I want from the html, I use Jsoup.

String htmlString = EntityUtils.toString(entity4); // full html as a string                                 
Document htmlDoc = Jsoup.parse(htmlString); // .. as a Jsoup Document
Elements tables = htmlDoc.getElementsByTag("table"); //important part

Now I can just load tables.toString() in the WebView and it displays. Now I want to link a CSS file which I store inside my assets folder with this page. I know I can have something like

<LINK href="styles/file.css" type="text/css" rel="stylesheet">

In my html, but how do I link it so that it uses the one I’ve stored locally?

—EDIT—
I’ve now changed to this:

StringBuilder sb = new StringBuilder();
    sb.append("<HTML><HEAD><LINK href=\"file:///android_asset/htmlstyles_default.css\" type=\"text/css\" rel=\"stylesheet\"/></HEAD><body>");
    sb.append(tables.toString());
    sb.append("</body></HTML>");
    return sb.toString();

Somehow I do not get the styles applied to the page. Is it the location path I used that is wrong?

    Seva Alekseyev is right, you should store CSS files in assets folder, but referring by file:///android_asset/filename.css URL doesn’t working for me.

    There is another solution: put CSS in assets folder, do your manipulation with HTML, but refer to CSS by relative path, and load HTML to WebView by loadDataWithBaseURL() method:

    webView.loadDataWithBaseURL("file:///android_asset/", htmlString, "text/html", "utf-8", null);

    E.g. you have styles.css file, put it to assets folder, create HTML and load it:

    StringBuilder sb = new StringBuilder();
sb.append("<HTML><HEAD><LINK href=\"styles.css\" type=\"text/css\" rel=\"stylesheet\"/></HEAD><body>");
sb.append(tables.toString());
sb.append("</body></HTML>");
webView.loadDataWithBaseURL("file:///android_asset/", sb.toString(), "text/html", "utf-8", null);

    P.S. I’ve come to this solution thanks to Peter Knego’s answer.
