 下面的示例代码，在一个scroll-view中嵌套了一个list-view。在list-view上设置了custom-nested-scroll="true"。

+5. 父组件配置`nested-scroll-child`后，父组件惯性滚动时会让`nested-scroll-child`配置的子元素进行滚动。从而触发`nestedprescroll`协商处理滚动事件
+6. 滚动行为停止后会触发`stopnestedscroll`事件
+
+**注意：**
++ 仅Android平台支持嵌套滚动协商
++ 嵌套滚动协商仅支持竖向滚动，横向滚动不支持
++ nested-scroll-child设置的元素必须配置custom-nested-scroll = true，否则配置无效。
