Xamarin写Android程序时,通常要使用按中文首字母分组显示(如通讯录) 。
于是需要被迫包含CJK,不过包含后包肯定是会变大的,于是。。。。自己写了一个硬枚举的中文转拼音的类。
原理是这样的:
代码如下 | 复制代码 |
publicclassPinYinUtils { privatestaticreadonlyDictionary {
{"猿","YUAN"} // 等............ }; /// /// Return to the first letter /// /// Chinese word /// /// GetFirstPinyinChar("张三") /// will return "Z" /// Can be used for address book index and so on /// /// publicstaticstringGetFirstPinyinChar(stringword) { if(word.Length == 0)return"#"; var firstLetter = word[0].ToString(); if(PinYinDict.ContainsKey(firstLetter)) { returnPinYinDict[firstLetter]; } returnfirstLetter; } /// /// return the chinese char's pinyin /// /// /// /// GetPinYin('福') /// will return "FU" /// /// publicstaticstringGetPinYin(charchineseChar) { var str = chineseChar.ToString(); if(PinYinDict.ContainsKey(str)) { returnPinYinDict[str]; } returnnull; } /// /// Get the phonetic abbreviation for Chinese char /// /// /// /// GetShortPinYin('福') /// will return "F" /// /// publicstaticstringGetShortPinYin(charchineseChar) { var str = chineseChar.ToString(); if(PinYinDict.ContainsKey(str)) { var first = PinYinDict[str].FirstOrDefault(); if(first == 0)returnnull; returnfirst.ToString(); } returnnull; } } |
