It's a bit tricky to do it in an EditText since it's editable. One approach you can take is - add a TextWatcher or onTextChangedListener to your EditText.

Override afterTextChanged of the TextWatcher and add a custom logic such as following.

String[] words = text.split();
SpannableStringBuilder sb = new SpannableStringBuilder();
for (String word in words) {
    SpannableString spanned = new SpannableString(word);
    spanned.setSpan( -- your font span here --);
    sb.append(spanned);
    sb.append(" ");
}

editText.setText(sb);

You have to add your own logic when and how you want to convert it. When you call editText.setText, afterTextChanged will get triggered. You need to take care of that recursion using some flag and handler for callbacks.

You could have something like this.

class FontWatcher(private val editText: EditText) : TextWatcher {
    private val handler = Handler()
    private var locked = false

    private val updateCallback = Runnable {
        locked = true
        // Create your spannable as mentioned above
        editText.setText(sb, TextView.BufferType.EDITABLE)
        editText.setSelection(sb.length)
        locked = false
    }

    override fun afterTextChanged(s: Editable) {
        if (!locked) {
            handler.removeCallbacks(updateCallback)
            handler.postDelayed(updateCallback, 300)
        }
    }
}

This is not optimized, but should help you get started.
