- 代码配置
side_bar.setLetters(letterArray)
side_bar.setSideBarListener(object: SideBarView.OnSideBarListener{
override fun onSideTouchState(sideBarView: SideBarView?, isTouch: Boolean) {
//根据isTouch判断是否需要显示提示View，具体参考demo
}
override fun onSideSelected(
sideBarView: SideBarView?,
position: Int,
currentY: Float,
selectedValue: String?
) {
//滑动选择成功回调，
//selectedValue为选中的字符串，position为字符串在letterArray中的位置
//可根据selectedValue去列表中查找需要滑动的位置（建议在添加数据时，对位置进行缓存，减少查找操作，参考demo）
}
