模仿通讯录按字母分类显示，汉字，英文自动按英文字母分类显示，滑动时用气泡显示最上面的汉字首字母提示，右侧字母栏点击快速定位
来源：互联网 发布：蓝犀牛搬家 知乎 编辑：程序博客网 时间：2024/05/03 22:10
废话不多说，先上图。
本Demo实现了如下功能：
1.根据汉字首字母，自动按英文字母分类显示。
2.滑动时，泡泡显示最上面的汉字首字母提示。
3.右侧字母栏点击快速定位，方便多数据的查找定位。
不足之处：
1.汉字转化得到拼音首字母的时候，我用到了一个pinyin4j-2.5.0.jar包，多音字和某些特殊汉字翻译不准确，如：我发现厦门，它会翻译成shamen，结果首字母变成了s。
结果我只好特殊处理了，朋友们有好的解决办法的话麻烦分享一下。
好了，废话不说了，上代码，总共3.java文件和3个配置文件。

还有string.xml和color.xml就不贴了，也就几个，缺啥就补啥。
好了，今天就到这吧，朋友们有啥问题的给我留言，只要我能解决的，一定告诉大家。
以为写个博客就10分钟的事情，实际上我用了一个小时，oh,My God!!
不过要是有人能用的上，我的时间也算是有所值了，呵呵。
有问题欢迎讨论，还望各位口下留情。
忘了，还缺了个图片：
和第三方jar包pinyin4j-2.5.0，jar包自己下吧，呵呵。
