PieRotateView ：这是一个可旋转，自动回弹，可惯性旋转的饼状图，多属性控制，使用简单，具备一个自定义View应有的基本素质
原理 ：自定义坐标象限，Move事件中不断叠加划过的角度，重绘arcPath，判断滑动或者点击到某个区块使用Region。功能 ：
1、可跟随手势旋转、旋转完自动回弹到区块中心。
2、惯性旋转+旋转完后回弹到区块中心。
3、点击某个区块自动旋转至该区块中心。
4、指针箭头指到某个区块内发送区块select事件。
5、提供了刷新入口(设置属性刷新、Data改变刷新)
基本素质 ：
1、旋转屏幕状态不丢失，转之前啥样，回来还是啥样（处理好onSaveInstanceState和onRestoreInstanceState）
2、暴露事件冲突接口，允许外界操作父控件的事件及该view自己的事件（因为这只是个View，没办法直接处理所有的滑动冲突场景）
3、内存抖动要小，防止内存溢出。
1、普通使用 ：没啥可说的，只有Down的点在圆的范围内才可以响应事件，否则通知父控件拦截2、下拉刷新及其他滑动冲突 ：
1、Down的点在圆内，通过onPromiseParentTouchListener方法中使用SwipeRefreshLayout.setEnabled(promise)通知外界设置SwipeRefreshLayout不可以滑动。
2、在SwipeRefreshLayout的OnRefreshListener中设置PierotateView的setEnableTouch(false)方法通知刷新期间，PierotateView不响应任何事件。
3、同理，监听AppBarLayout的滚动高度来控制只有完全展开才允许SwipeRefreshLayout下拉刷新和PierotateView旋转,否则都禁止

Step 1. Add it in your root build.gradle at the end of repositories：
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
implementation 'com.github.NoEndToLF:PieRotateView:1.0.3'
}
