自动生成Android屏幕适配的dimens.xml

最近团队再做Android App的屏幕适配,按照官方的办法是layout文件引用dimen变量, 变量放在多个不同分辨率下的dimens.xml文件中,分别放在不同的目录下,
./app/src/main/res/values-sw480dp-land/dimens.xml ./app/src/main/res/values-sw600dp-land/dimens.xml ./app/src/main/res/values-sw720dp-land/dimens.xml ./app/src/main/res/values-sw800dp-land/dimens.xml ./app/src/main/res/values-w820dp/dimens.xml
人工处理这些dimens.xml,感觉比较麻烦,就是个体力活,于是做了个工具类按比例自动化生成dimens.xml文件,效率瞬间提高了很多倍,如果需要特殊定义尺寸,放到另一个xml文件里面就行了。
values/dimens.xml 文件示例
<resources> <!-- Default screen margins, per the Android Design guidelines. --> <dimen name="activity_horizontal_margin">14dp</dimen> <dimen name="activity_vertical_margin">14dp</dimen> <dimen name="action_bar_height">50dp</dimen> <dimen name="tab_height">81dp</dimen> <dimen name="content_margin">18dp</dimen> <dimen name="list_title_height">63dp</dimen> <dimen name="report_table_header_height">54dp</dimen> <dimen name="report_category_height">54dp</dimen> <dimen name="fab_size_normal">72dp</dimen> <dimen name="fab_margin">14dp</dimen>
工具类代码,直接运行即可
