jstring dateString = (jstring)(*env)->GetobjectField(env, stat, idDate);
……然后一切正常。
解决方法到目前为止，这就是我所拥有的：我传递一个具有2个字段的对象：String和Integer作为参数，并且我想发送信息以在C部分中对其进行处理，这在当时并不重要…我抱怨在jstring声明
JNIEXPORT jint JNICALL Java_Tier3_NativeMethods_totalPalletsIn( JNIEnv *env,jclass cls,jobject stat) {jclass staticsitcs = (*env)->GetObjectClass(env,stat);// Here I try to get it using the IDjfieldID idDate = (*env)->GetFieldID(env,staticsitcs,'date','S');jstring dateString = (jstring)(*env)->GetStringRegion(env,stat,idDate);// Here converting whatever I get in jstring to char*char* date = (*env)->GetStringUTFChars(env,dateString,0);// Getting the 2nd field from the objectjfieldID idNumber = (*env)->GetFieldID(env,'amount','I');jint amount = (*env)->GetDoubleField(env,idNumber);// Calling C methodjint totalPallets = checkTotalPalletsIn(date,amount);(*env)->ReleaseStringUTFChars(env,date);return totalPallets;}
我想念什么？
