android图片复制小工具

用java做了个安卓图片复制的小工具，自己动手，丰衣足食。

[TOC]

原因

用sketch做好图后，导出的图片在一个文件夹内，命名大概如下：

  1. my@mdpi.png
  2. my@hdpi.png
  3. my@xhdpi.png
  4. my@xxhdpi.png

而安卓的图片的结构大概是这样的：

res

  • drawable-mdpi
  • drawable-hdpi
  • drawable-xhdpi
  • drawable-xxhdpi

也就是说，图片复制的时候需要一个一个分开来放，比较麻烦。

如图所示：

代码

所以就用java写了个jar来自动完成。

使用方法

导出jar后再命令行中执行

其中,fromFolder是图片文件夹，toFolder指向安卓的res文件夹

java -jar copyImage.jar fromFolder toFolder(res)
