CustomFontHtml

Custom font html is an Android library to handle custom font, via custom loaders, with a Html.fromHtml like function.

CustomHtml.fromHtml(String string, ICustomFontLoader fontLoader)

Example

CaseInsensitiveAssetFontLoader fontLoader = new CaseInsensitiveAssetFontLoader(
    getActivity().getApplicationContext());

maintv.setText(CustomHtml
    .fromHtml(
        "Example using font awesome:<br/>"
            + "<font face='fontawesome'>&#xf17b;</font> Android<br/>"
            + "<font face='fontawesome'>&#xf024; <font color='red'>&#xf024;</font></font> flag and red flag<br/>"
            + "<font face='fontawesome'>&#xf1b9;</font> car<br/>"
            + "<font face='fontawesome'>&#xf07c;</font> folder<br/>"
            + "<font face='libertine'>LinLibertine example</font>",
        fontLoader));

// All caps mess rendering.
disableAllCaps(mainbuton);
mainbuton.setText(CustomHtml.fromHtml(
    "<font face='fontawesome'>&#xf17b;</font> Android button",
    fontLoader));
    
@TargetApi(14)
public void disableAllCaps(TextView v) {
    v.setTransformationMethod(null);
    if (Build.VERSION.SDK_INT >= 14) {
        v.setAllCaps(false);
    }
}   

Result

Font loaders

ICustomFontLoader

All font loaders implements ICustomFontLoader.

SimpleAssetFontLoader(Context context)

SimpleAssetFontLoader loads font from asset using face attribute of the font tag and a given extension in a given directory ("otf" and "assets" by default)

Search is case sensitive so to match FontAwesome.otf, tag MUST had face attribute strictly equal to FontAwesome or you can use CaseInsensitiveAssetFontLoader

setFolder(String folder)

Set the folder to search in

setExtension(String extension)

Set the extension to look for. Supported by Android are EXT_OTF and EXT_TTF (otf and ttf respectively)

CaseInsensitiveAssetFontLoader(Context context, String folder)

CaseInsensitiveAssetFontLoader works like SimpleAssetFontLoader but in a case insensitive manner. That's why the folder has to be given at the creation to list and normalize file names for further use. This loader loads both otf and ttf and in case of duplication, last seen is kept.

CaseInsensitiveAssetFontLoader(Context context)

Same as CaseInsensitiveAssetFontLoader(Context context, ""). This assume that fonts are in the root of the assets folder

Notes

Both implementation caches the font once loaded in an LRU to spare resources. When font is unavailable, it fallbacks to system default.
