Android Span标签，故名思意

//你要改变的文本，开时索引（从1开始），结束索引
private SpannableString SetFontColor(String str, int start, int end) {
        SpannableString spannableString = new SpannableString(str);
        ForegroundColorSpan foregroundColorSpan = new ForegroundColorSpan(Color.parseColor("#2F4DD2"));
        spannableString.setSpan(foregroundColorSpan, start, end, spannableString.SPAN_EXCLUSIVE_EXCLUSIVE);
        return spannableString;
    }

textView.setText(SetFontColor("王富贵",1,2));
