jint 轉(zhuǎn) jstring?

jint?cno=2;

char buf[64];

sprintf(buf, "%d",cno);

std::string namestd1= "";

namestd1.append(buf);

?jstring 轉(zhuǎn)char

const char * str = env->GetStringUTFChars(name,0);

char c[120] = "";//調(diào)用c++拼接字符函數(shù)strcat(c,str);

//釋放env->ReleaseStringUTFChars(name,str);

或者

char names[40] ;

sprintf(names, "%s", name);

puts(names);

?char??轉(zhuǎn)?jstring

char s[256] = {0};

strcpy(s, namestd.c_str());

jstring a=env->NewStringUTF(namestd.c_str())
