How to use custom font with WebView

Viewed 65071

Now I want to display some unicode characters and I have used tag: <font face=" Arial">something here</font>. But it seems that WebView can not find the Arial font because I can only see UFO-characters. Do I have to copy arial.ttf to somewhere or how can I use this TrueType font with WebView? Thanks.

Apparently, you can use a custom font for WebView, as @raychung above suggested. But this won't work for 2.1 (Bug is reported here). This should work for 1.5, 1.6 and 2.2.

You can put your custom font TTF file in your /assets folder, then in your CSS file you can put in:

@font-face { 
    font-family: "myIPA"; 
    src: url('IPA.TTF'); 
}
.phon, .unicode
{
    display: inline;    
    font-family: 'myIPA', Verdana, sans-serif;  
    font-size: 14pt;
    font-weight: 500;
    font-style:normal;
    color: black;
}

You can now reference this font style in your HTML file.

You can get it to work on all versions by copying the font file from your assets to your files folder on the first launch of the app, and then reference it as:

"@font-face {
 font-family: cool_font;
 src: url('file://"+ getFilesDir().getAbsolutePath() 
  + "/cool_font.ttf');
}"

I used below code for rtl direction with persian font, hope someone used this code or someone suggest me best way. thanks

            String myCustomStyleString="<style type=\"text/css\">@font-face {font-family: MyFont;src: url(\"file:///android_asset/fonts/BYEKAN.ttf\")}body,* {font-family: MyFont; font-size: medium;text-align: justify;}</style>";
                    webView.loadDataWithBaseURL("", myCustomStyleString+"<div style=\"direction:rtl\">"+myHtm+"</div>", "text/html", "utf-8", null);

This works great for me on all the devices I've tested it on.

Place your font files in /src/main/assets/fonts, then use this method:

public class HTMLUtils {

    public static String getLocalFontInHTML(String html, String fontFamily, String fontFileName) {

      return "<!DOCTYPE html>\n" +
            "<html>\n" +
            "<head>\n" +
            "<style>" +
            "@font-face {" +
            "font-family: " + fontFamily + ";" +
            "src: url('" + fontFileName + "');" +
            "}" +
            "* {font-family: '" + fontFamily + "' !important;}" +
            "* {font-size: 1rem !important;}" +
            "</style>" +
            "</head>\n" +
            "<body>\n" +
            html +
            "\n" +
            "</body>\n" +
            "</html>";
     }
}

as follows

webView.loadDataWithBaseURL("file:///android_asset/", HTMLUtils.getLocalFontInHTML(item.text, Config.FONT_FAMILY, Config.REGULAR_FONT),"text/html", "UTF-8", null);

where

public static final String FONT_FAMILY = "Montserrat";

public static final String REGULAR_FONT = "fonts/Montserrat-Regular.otf";

Hope it helps someone!

If you want to keep the font size from your html code remove

 "* {font-size: 1rem !important;}"

Have in mind that 1rem is equivalent to about 14sp
