可以支持富文本

在process(boolean setText)方法中的settext之前处理newText，例如
SpannableString spannableString = new SpannableString(newText);
int a = newText.toString().indexOf(data);
Log.e(TAG, "a=" + a);
while (a != -1) {
ForegroundColorSpan colorSpan = new ForegroundColorSpan(ContextCompat.getColor(getContext(), R.color.colorAccent));
spannableString.setSpan(colorSpan, a, data.length() + a, Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
a = newText.toString().indexOf(data, a + 1);
Log.e(TAG, "a=" + a);
}
setText(spannableString);
