如何更改单词之间的距离？

Question

如何使用这些方法在 Android Studio 中更改字符串中单词之间的距离？我需要距离大约是标准大小的一半 space。

val spanMsg = SpannableStringBuilder()
    msg?.forEachIndexed { i, char ->//replacing non-printable characters
                                    //with their code and highlighting
        if (char.isControlChar()) {//checking for non-printable characters
            spanMsg.appendWithSpan(" ", RelativeSizeSpan(BLOCKS_INDENT))
            for(x in toHex(Character.toString(char)
                                    .toByteArray(StandardCharsets.UTF_16BE))!!) {
                spanMsg.appendWithSpan(
                        x,
                        ForegroundColorSpan(Color.WHITE),
                        BackgroundColorSpan(Color.BLACK)
                )
            }

fun SpannableStringBuilder.appendWithSpan(text: CharSequence, vararg what: Any) {
this.append(text)
what.forEach {
    this.setSpan(
            it,
            this.length - text.length,
            this.length,
            Spanned.SPAN_EXCLUSIVE_EXCLUSIVE
    )
}

据我了解，在BackgroundColorSpan(Color.BLACK)之后可以加一个参数来改变字间距
