之前有个做输入法的需求，原本的字库文件信息特别大，需要都写到so里面去方便调用。但是原始的资源不符合使用，所以需要转成代码中能够调用的格式。另外，同时需要数字键九宫格匹配相应的字。
1. 原始文件
原始文件——单字
原始文件——多字
不太清楚第二个和第三个数据是什么意思，不过我们只需要提取第一个和最后一个数据即可。
2.完成思路
- 首先利用分隔符获取第一个和最后一个数据
- 每一项与下一项判断是否最后一个元素相同，如果相同证明是一个发音的字，然后将相同拼音的字放到一个list中。
- 对应每一个拼音字母的数字按键的获取比较简单，可以直接建立两个list，一个是26个字母，一个是26个字母所对应的数字按键。之后对每个字母的索引数找对应的数字按键list的索引。
3. 代码
