JNI修改Native方法数组参数中数组里面的元素值

JNIEXPORT jintArray JNICALL java_com_example_feisou_a02_1helloworld_JNI_arrElementsIncrease        (JNIEnv *env, jobject thiz, jintArray jarray){    jsize  length = (*env)->GetArrayLength(env,jarray);    LOGD("length = %d",length);    //jboolean iscopy;    jint* arrayPointer = (*env)->GetIntArrayElements(env,jarray,NULL);    int i;    for(i=0;i<length;i++){        *(arrayPointer+i) += 10;    }    (*env)->SetIntArrayRegion(env, jarray, 0,length,arrayPointer);    return jarray;
}
public void click2(View V){    int[] array = new int[]{1,2,3,4,5};    for(int i: jni.arrElementsIncrease(array)){        Log.d("test",i+"");    }  }
