Android下調用jni時進行的轉碼操作執行個體

之前幫人家解決亂碼問題時回過一個文章 現在總結在部落格裡 留起來 

 

 

bool handleString(char* name)<br /> {<br /> jstring rtnname = 0;<br /> int slenname = strlen(name);<br /> unsigned short * namebuffer = 0;<br /> if( slenname == 0 )<br /> rtnname = mEnv->NewStringUTF(name);<br /> else<br /> {<br /> wchar_t* wname = NULL;<br /> setlocale(LC_ALL,"");</p><p> int namelength=mbstowcs(wname,name,strlen(name)*2);</p><p> namebuffer = (unsigned short *)malloc(namelength*2 + 1 );<br /> if((rtnname = mEnv->NewString( (jchar*)namebuffer, namelength )) == NULL)<br /> return false; </p><p> if( namebuffer )<br /> free(namebuffer );<br /> } </p><p> return true;<br /> }</p><p> bool isASCII(const char* chp)<br /> {<br /> char ch;<br /> bool flag;<br /> while ((ch = *chp++))<br /> {<br /> flag = false;<br /> if (ch & 0x80)<br /> {<br /> flag = true;<br /> break;<br /> }<br /> }<br /> return flag;<br /> }</p><p>

 

 

有朋友反映找不到mbstowcs

#include <locale.h>
#include <stdlib.h>

就可以找到了
