BasePickerView (pickerview API)

java.lang.Object
- android.view.View
- - org.jaaksi.pickerview.widget.BasePickerView<T>

所有已实现的接口:

android.graphics.drawable.Drawable.Callback, android.view.accessibility.AccessibilityEventSource, android.view.KeyEvent.Callback

直接已知子类:

PickerView
```
public abstract class BasePickerView<T>
extends android.view.View
```
滚动选择器,带惯性滑动 https://github.com/1993hzw/Androids/blob/master/androids/src/cn/forward/androids/views/ScrollPickerView.java 做一下修改：改为adapter填充数据，不再直接持有数据源。提供两种常用adapter 增加属性itemSize，支持高度为wrap_content时，根据itemCount和visibleItemCount计算总高度，便于动态改变visibleItemCount 提供接口Formatter 外界可以对显示的文案处理。比如添加把2018变成2018年，8变成 08月，MixedTimePicker中用处更大绘制中心item由绘制drawable改为由接口CenterDecoration控制，提供默认实现。用户可以自定义，更强大，使用更方便修改数据源size < visibleItemCount时强制不进行循环修改默认选中第0个
