## 四.一些细节问题 ## 四.一些细节问题
由于默认屏幕坐标系和常见数学坐标系的小差别([坐标系问题点这里](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Base/%5B1%5DCoordinateSystem.md)，所以在角度上必然也会存在一些区别，例如： 由于默认屏幕坐标系和常见数学坐标系的小差别([坐标系问题点这里](https://github.com/GcsSloop/AndroidNote/blob/master/CustomView/Base/%5B1%5DCoordinateSystem.md))，所以在角上必然也会存在一些区别，例如：
**在常见的数学坐标系中角度增大方向为逆时针，** **在常见的数学坐标系中角度增大方向为逆时针，**
