如何把char str,或unsigned char str转换成CString
4星 · 用户满意度95%
要将`const char* result`从`const char`类型转换为`unsigned short`类型的字符串,你可以使用以下方法:
```cpp
#include <cstring>
// 将const char*转换为unsigned short*
unsigned short* convertToUnsignedShort(const char* input) {
size_t length = std::strlen(input);
unsigned short* result = new unsigned short[length + 1];
for (size_t i = 0; i < length; ++i) {
result[i] = static_cast<unsigned short>(input[i]);
}
result[length] = 0; // 添加字符串结尾的空字符
return result;
}
// 在JNI环境中将unsigned short*转换为jstring
jstring convertToJString(JNIEnv* env, const unsigned short* input) {
jstring result = env->NewString(reinterpret_cast<const jchar*>(input), env->GetStringLength(reinterpret_cast<const jchar*>(input)));
return result;
}
extern "C" JNIEXPORT jstring JNICALL
Java_com_example_MyClass_convertToJString(JNIEnv* env, jobject /* this */, jstring input) {
const char* result = candidateAdjust(reinterpret_cast<const char*>(pinyinstore), reinterpret_cast<const char*>(str));
unsigned short* convertedResult = convertToUnsignedShort(result);
jstring convertedString = convertToJString(env, convertedResult);
delete[] convertedResult;
return convertedString;
}
```
然后,在Java类中调用`convertToJString`方法来获取转换后的jstring对象:
```java
public class MyClass {
static {
System.loadLibrary("your_native_library");
}
public native String convertToJString(String input);}
```
请确保将`your_native_library`替换为你的本地库的名称。这样就可以将`result`由`const char`类型转换为`unsigned short`类型的字符串,并将其转换为jstring类型了。
