用那會(huì)搜兩下子 太復(fù)雜了 亂七八糟的 明明幾句話的事

溫度顯示那就是了 不縮小了 就這樣吧

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);
