![](images/icon.png) 2 | 3 | HenCoder 绘制 4 练习项目 4 | === 5 | 6 | ### 这是什么？ 7 | 8 | 这不是一个独立使用的项目，它是 [HenCoder Android 开发进阶：UI 1-4 绘制的辅助](http://hencoder.com/ui-1-4) 的配套练习项目。 9 | 10 | ### 怎么用？ 11 | 12 | 项目是一个可以直接运行的 Android App 项目，项目运行后，在手机上打开是这样的： 13 | 14 | ![](images/preview.png) 15 | 16 | 工程下有一个 `/practice` 目录： 17 | 18 | ![](images/project_practice.png) 19 | 20 | 你要做的是就是，在 `/practice` 下的每一个 `PracticeXxxView.java` 文件中写代码，绘制出和页面上半部分相同的效果。例如写 `Practice01ClipRectView.java` 以绘制出经过平移的图形。就像这样： 21 | 22 | ![](images/preview_after.png) 23 | 24 | > 当然，没必要做得和示例一毛一样。这是一个练习，而不是一个超级模仿秀，关键是把技能掌握。 25 | 26 | 如果做不出来，可以参考 `/sample` 目录下的代码： 27 | 28 | ![](images/project_sample.png) 29 | 30 | 练习做完，绘制第四期（绘制的辅助）的内容也就掌握得差不多了。 --------------------------------------------------------------------------------
