Android字体颜色统一化标准化。

在开发中往往有很多一样的代码，所以我们通常抽成一个公共类，以便复用，同样也是为了代码的简洁性。比如常量，我们会通常放到一个类里统一调用，还有utils、adapter等等。但是也有不少人会忽略字体和颜色的统一和标准。

1.字体（values目录下的dimens.xml文件中）

<resources> <!-- Default screen margins, per the Android Design guidelines. --> <dimen name="activity_horizontal_margin">16dp</dimen> <dimen name="activity_vertical_margin">16dp</dimen> <!-- 字体 --> <dimen name="font_larger">22sp</dimen> <dimen name="font_large">18sp</dimen> <dimen name="font_normal">16sp</dimen> <dimen name="font_small">14sp</dimen> <dimen name="font_smaller">12sp</dimen> <dimen name="font_smallest">10sp</dimen> <!-- margin and padding --> <dimen name="spacing_huge">40dp</dimen> <dimen name="spacing_larger">34dp</dimen> <dimen name="spacing_large">24dp</dimen> <dimen name="spacing_biger">20dp</dimen> <dimen name="spacing_big">18dp</dimen> <dimen name="spacing_normal">14dp</dimen> <dimen name="spacing_small">12dp</dimen> <dimen name="spacing_smaller">10dp</dimen> <dimen name="spacing_smallest">8dp</dimen> <dimen name="spacing_tiny">6dp</dimen> <dimen name="spacing_tinyer">4dp</dimen> <dimen name="spacing_tinyest">2dp</dimen> </resources>

2.颜色（values目录下的color.xml文件中）

<?xml version="1.0" encoding="utf-8"?> <resources> <!--主题色--> <color name="colorPrimary">#e55625</color> <color name="colorPrimaryDark">#D54615</color> <color name="colorAccent">#FF4081</color> <color name="white">#ffffff</color> <color name="black">#333333</color> <color name="blue">#1C90DB</color> <color name="green">#3BB032</color> <color name="backGreen">#f3f6f5</color> <color name="gray">#d3d3d3</color> <color name="backGray">#eeeeee</color> <color name="lightGray">#fafafa</color> <!--字体的灰色--> <color name="indexTextGray">#939393</color> <color name="red">#e53935</color> <color name="transparent">#00000000</color> <color name="trantracent">#22000000</color> <color name="trantracent_wode">#55000000</color> <color name="grey_text_color_normal">#8A8A8A</color> <color name="grey_line_bg">#E4E4E4</color> <color name="original_border_color">#F18459</color> </resources>
