java 如何获取指定汉字的拼音索引字母

Answer 1

public class GetFirstLetter {

private static final int GB_SP_DIFF = 160;
private 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};
private 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'};

public static String getFirstLetter(String oriStr) {
String str = oriStr.toLowerCase();
StringBuffer buffer = new StringBuffer();
char ch;
char[] temp;
for (int i = 0; i < str.length(); i++) {
ch = str.charAt(i);
temp = new char[] {
ch};
byte[] uniCode = new String(temp).getBytes();
if (uniCode[0] < 128 && uniCode[0] > 0) {
buffer.append(temp);
}
else {
buffer.append(convert(uniCode));
}
}
return buffer.toString().substring(0,1);
}

private static char convert(byte[] bytes) {

char result = '-';
int secPosvalue = 0;
int i;
for (i = 0; i < bytes.length; i++) {
bytes[i] -= GB_SP_DIFF;
}
secPosvalue = bytes[0] * 100 + bytes[1];
for (i = 0; i < 23; i++) {
if (secPosvalue >= secPosvalueList[i] &&
secPosvalue < secPosvalueList[i + 1]) {
result = firstLetter[i];
break;
}
}
return result;
}

public static void main(String s[]){

System.out.print(getFirstLetter("好"));
}

如果是return buffer.toString()则可以返回一句话中每个字的拼音索引
有点分就更好了

这个是需要词库的，哈哈。提高悬赏分到200吧。呵呵。
