ChinaMapView ：这是一个可拖拽，可点击，可手势放大的自定义**地图组件，使用简单，具备一个自定义View应有的基本素质
原理 ：画地图用path，缩放拖拽用Matrix，判断点击位置用Region，判断滑动和缩放过程中的Map边界用Matrix.mapRect功能 ：
1、可随手势拖动，到边界抵消相应方向的滑动，且只有down的点在map内才可以拖动。
2、可随缩放手势放大缩小，放大缩小的手势不做任何限制，只要在View内即可。
3、点击某个省份回调该Select事件，传递出省份名字
4、提供了刷新入口(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 ：只有Down的点在map的范围内才可以响应拖拽事件，否则通知父控件拦截；缩放事件不做限制。2、下拉刷新及其他滑动冲突 ：
1、拖拽事件：Down的点在map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、缩放事件：在MyScaleGestureDetector的onScaleBegin方法中通过onPromiseParentTouchListener方法中使用SwipeRefreshLayout.setEnabled(promise)通知外界设置SwipeRefreshLayout不可以滑动。
3、在SwipeRefreshLayout的OnRefreshListener中设置ChinaMapView的setEnableTouch(false)方法通知刷新期间，ChinaMapView不响应任何事件。
4、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ChinaMapView的事件响应,否则都禁止

修改ChinaMapModel对象后，刷新View
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:ChinaMapView:1.0.2'
}
