RTF File Content

Code

 val raw: InputStream = resources.openRawResource(resourceID)
    val stream = ByteArrayOutputStream()
    var i: Int
    try {
        i = raw.read()
        while (i != -1) {
            stream.write(i)
            i = raw.read()
        }
        raw.close()
    } catch (e: IOException) {
        e.printStackTrace()
    }

    ConvertHTML=Html.fromHtml(stream.toString(),HtmlCompat.FROM_HTML_MODE_LEGACY)

    text_view.text = ConvertHTML;
