There\'s a method for altering background color but not font.
Any ideas?

    This worked for me 

    myWebView.getSettings().setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
    view.loadUrl(
        "javascript:document.body.style.setProperty(\"color\", \"white\");"
    );
  }
});

    I'm not sure I understand. The WebView just displays the HTML you give it so you would just use normal HTML/CSS to modify the content displayed within.

    This is the easiest way I found (change the text color to white for example):

    webview.loadUrl("javascript:document.body.style.color=\"white\";");

    something like

    String text = "<html><head>"
          + "<style type=\"text/css\">body{color: #fff; background-color: #000;}"
          + "</style></head>"
          + "<body>"                          
          + your_string_text_here
          + "</body></html>";

webview1.loadData(text, "text/html", "utf-8");

    I had to put it in the onPageFinished method.

    _webView.setWebViewClient(new WebViewClient() {
    public void onPageFinished(WebView view, String url) {
        _webView.loadUrl(
            "javascript:document.body.style.setProperty(\"color\", \"white\");"
        );
    }
});

    When the buffer is SPANNABLE, modifying the HTML directly is an ideal solution. The font, color, typeface, style can all be affected through HTML:

    String szMessage = "<font face='trebuchet' size=30><a href=zz><b>click me</b></a></font>";

TextView tv = (TextView)findViewById(R.id.tv_message);
tv.setText(Html.fromHtml(szMessage), BufferType.SPANNABLE);
