以上的类主要做一些汉字ascii转拼音的操作;

TestContactBean:

package com.example.test29api.slider_contact

class TestContactBean(val name: String = "", val phone: String = "") : NewSideBar.Indexable<String> {
    override val indexable: String
        get() {
            return name
        }
}

这里不要忘了继承NewSideBar的Indexable接口,便于获取需要排序的词组;
