一个textview表示价格的时候，¥符号要小一些，好吧，就按照下面这代码搞就行了。

 String text = new String("￥" + "2000");
            Log.i("cdscvdscdscsd", text);
            SpannableString spannableString = new SpannableString(text);
            int size = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, 11, getResources()
                    .getDisplayMetrics());

            spannableString.setSpan(new AbsoluteSizeSpan(size), 0, 1, Spanned
                    .SPAN_EXCLUSIVE_EXCLUSIVE);//设置字体大小
            spannableString.setSpan(new ForegroundColorSpan(getResources().getColor(R.color.green)), 0, 1,
                    Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//设置字体颜色

            int size2 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP, 16, getResources
                    ().getDisplayMetrics());

            spannableString.setSpan(new AbsoluteSizeSpan(size2), text.length() - 1, text.length(),
                    Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//设置字体大小
            spannableString.setSpan(new ForegroundColorSpan(getResources().getColor(R.color.green)), text.length
                    () - 1, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//设置字体颜色
                    
                    tv_title_name.setText(spannableString);

一个textview字体大小一样，但是里面个别字颜色不一样，且这些字是动态获取。

String str1 = "<font color='#f68113'>" + RandomUtil.getNum() + "</font>";
String str2 = "<font color='#f68113'>" + RandomUtil.getNum() + "</font>";

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fresh_sucess);
    textView = (TextView) findViewById(R.id.tv_fresh_info);
    textView.setText(Html.fromHtml("您的简历优鲜度提升了" + str1 + "%，<br/>排序更新提前了" + str2 + "位！<br/>您的简历将会精准推送到更多企业！"));

}
