该开源库的主要作用就是简化自定义View过程中的一些流程，让自定义View更简单，更方便，更高效，例如：

* 继承 `CustomView` 以自动获取 View 大小以及默认画笔。
* 使用 `CanvasAidUtils` 绘制当前坐标系以检查绘制的位置。
* 使用 `MathUtils` 方便的进行角度弧度转换，计算距离。

除此之外，它还有更多的工具和辅助类来帮助你更方便的自定义View，更多信息请查看下面表格。

如果你对此有什么比较好的建议，欢迎提交 Issues 来告诉我。

## 如何添加该开源库

#### Gradle:

**Step 1. 添加JitPack仓库**

在当前项目的根目录下的 `build.gradle` 文件中添加如下内容:

``` gradle
allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}
```

**Step 2. 添加项目依赖**

``` gradle
dependencies {
        compile 'com.github.GcsSloop:ViewSupport:v1.3.0'
}
```
