Span的简单用法

用那会搜两下子 太复杂了 乱七八糟的 明明几句话的事

温度显示那就是了 不缩小了 就这样吧

String temperatureStr = null;
        if (weather != null) {
            temperatureStr = weather.showapi_res_body.now.temperature + "℃";
            Spannable sp = new SpannableString(temperatureStr);
            sp.setSpan(new AbsoluteSizeSpan(15, true), temperatureStr.length() - 1, temperatureStr.length(),
                    Spanned.SPAN_INCLUSIVE_EXCLUSIVE);
            weather_temperature_tv.setText(sp);
