Without making change in the content of webpage you cant change the font.

WebView is basically a view to display web pages That web pages may be static(eg html) or dynamic. But it doesn't change the look and feel of web page. so It wil display the text exactly same as that of webpage. If you need to change the font then you have to change it in webpage (may be in html).

Please have a look on What is WebVIew

// Put your font file in assets

private WebView wv;

wv = (WebView)findViewById(R.id.wv);
wv.setBackgroundColor(Color.BLACK);

String my_text=getData("I am android developer");

wv.loadDataWithBaseURL("file:///android_asset//Gill Sans MT.ttf", t, "text/html", "UTF-8", "null" );

private String getData(String s){

    String htmlData="<font color='white'>" + s + "</font>";
     String PAGE_HTML =
            "<html>\n" +
            "  <style type=\"text/css\"> \n" + 
            "   @font-face { \n" + 
            "       font-family: MyFont; \n" + 
            "       src: url(\"file:///android_asset/Gill Sans MT.ttf\") \n" + 
            "   } \n" + 
            "   body { \n" + 
            "       font-family: MyFont; \n" + 
            "       font-size: medium; \n" + 
            "       text-align: justify; \n" + 
            "   } \n" + 
            "  </style> \n" + 
            "  <body>\n" + 
            "    "+htmlData+"<br>\n" + 

            "  </body>\n" + 
            "</html>";

    return PAGE_HTML;

}
