Rendering HTML in a WebView with custom CSS
You could use WebView.loadDataWithBaseURL
htmlData = "<link rel=\"stylesheet\" type=\"text/css\" href=\"style.css\" />" + htmlData;
// lets assume we have /assets/style.css file
webView.loadDataWithBaseURL("file:///android_asset/", htmlData, "text/html", "UTF-8", null);
And only after that WebView will be able to find and use css-files from the assets directory.
ps And, yes, if you load your html-file form the assets folder, you don't need to specify a base url.
I assume that your style-sheet "style.css" is already located in the assets-folder
-
load the web-page with jsoup:
doc = Jsoup.connect("http://....").get();
-
remove links to external style-sheets:
// remove links to external style-sheets doc.head().getElementsByTag("link").remove();
-
set link to local style-sheet:
// set link to local stylesheet // <link rel="stylesheet" type="text/css" href="style.css" /> doc.head().appendElement("link").attr("rel", "stylesheet").attr("type", "text/css").attr("href", "style.css");
-
make string from jsoup-doc/web-page:
String htmldata = doc.outerHtml();
-
display web-page in webview:
WebView webview = new WebView(this); setContentView(webview); webview.loadDataWithBaseURL("file:///android_asset/.", htmlData, "text/html", "UTF-8", null);
here is the solution
Put your html and css in your /assets/ folder, then load the html file like so:
WebView wv = new WebView(this);
wv.loadUrl("file:///android_asset/yourHtml.html");
then in your html you can reference your css in the usual way
<link rel="stylesheet" type="text/css" href="main.css" />
It's as simple as is:
WebView webview = (WebView) findViewById(R.id.webview);
webview.loadUrl("file:///android_asset/some.html");
And your some.html needs to contain something like:
<link rel="stylesheet" type="text/css" href="style.css" />
If you have your CSS in the internal file storage you can use
//Get a reference to your webview
WebView web = (WebView)findViewById(R.id.webby);
// Prepare some html, it is formated with css loaded from the file style.css
String webContent = "<!DOCTYPE html><html><head><meta charset=\"UTF-8\"><link rel=\"stylesheet\" href=\"style.css\"></head>"
+ "<body><div class=\"running\">I am a text rendered with INDIGO</div></body></html>";
//get and format the path pointing to the internal storage
String internalFilePath = "file://" + getFilesDir().getAbsolutePath() + "/";
//load the html with the baseURL, all files relative to the baseURL will be found
web.loadDataWithBaseURL(internalFilePath, webContent, "text/html", "UTF-8", "");
