javaSE及android汉字求索引【还有iphone汉字求拼音(求了拼音索引也就好了)】.doc

GB 2312-80 把收录的汉字分成两级。第一级汉字是常用汉字，计 3755 个，置于 1655 区，按汉语拼音字母笔形顺序排列；第二级汉字是次常用汉字， 计 3008 个，置于 5687 区，按部首笔画顺序排列，所以本程序只能查到对一级汉字的声母。同时对符合声母（zh，ch，sh）只能取首字母（z，c，s）如果是return buffer.toString()则可以返回一句话中每个字的拼音索引Java的这段代码与android的那段代码所用的思想是一样的，但是java的这段代码只能用于J2SE中要想在android中使用的话还得用android的那段，如果是做iphone开发的话同样可以用（我自己试过但是没成功，主要是编码不合适，如果你有技术的话可以自己试着转换下编码）。另外还有一部分内容是网上找来的关于iphone汉字求拼音的代码，由于它用的是C#语言，所用我看不懂。如果有开发iphone的兄弟的话可以下来看看。废话不多说了，我们来看看代码吧。JAVA_SE专用部分：public class HzPyUtil / 国标码和区位码转换常量static final int GB_SP_DIFF = 160;/ 存放国标一级汉字不同读音的起始区位码static final int secPosvalueList = 1601, 1637, 1833, 2078, 2274, 2302,2433, 2594, 2787, 3106, 3212, 3472, 3635, 3722, 3730, 3858, 4027,4086, 4390, 4558, 4684, 4925, 5249, 5600 ;/ 存放国标一级汉字不同读音的起始区位码对应读音static final char firstLetter = a, b, c, d, e, f, g, h,j, k, l, m, n, o, p, q, r, s, t, w, x,y, z ;/ 获取一个字符串的拼音码public static String getFirstLetter(String oriStr) String str = oriStr.toLowerCase();StringBuffer buffer = new StringBuffer();char ch;char temp;for (int i = 0;
