先看UC浏览器的温度

uc_weather.png 要实现17°这样的极细的字体
自定义View
继承TextView，在onDraw方法中设置画笔粗细
TextPaint tp = new TextPaint();
tp.setAntiAlias(true);
tp.setStyle(Paint.Style.FILL_AND_STROKE);
tp.setStrokeWidth(0.1f);
setStrokeWidth方法默认参数是0，而且不接受负数参数，也就是说，只能加粗不能变细。Spannable
再试试
SpannableSpannable s = new SpannableString("17°29");
s.setSpan(new AbsoluteSizeSpan(30, true), 0, 3, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
s.setSpan(new AbsoluteSizeSpan(30, false), 3, 5, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
s.setSpan(new RelativeSizeSpan(2.0f), 0, 3, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
tv.setText(s);
效果也是一样，可以改变字体大小，但是只能加粗不能变细
Thin字体
从字体本身出发，尝试寻找细细的字体

D:\Android\sdk\platforms\android-N\data\fonts【TextView极细字体】
fonts.xml里配置了字体的别名
