画面遷移サンプル(android)

-Classes/HelloWorldScene2.h HelloWorldScene.hをコピーして作る

}
void HelloWorldScene2::menuCloseCallback(Ref* pSender)
{
    // 最初の画面に戻るように
    Director::getInstance()->pushScene(HelloWorld::createScene());
}

-Classes/HelloWorldScene.cpp

#include "HelloWorldScene2.h"
// 略
void HelloWorld::menuCloseCallback(Ref* pSender)
{
     // ボタンイベントあたりに画面遷移コードを記述
     Director::getInstance()->pushScene(HelloWorldScene2::createScene());
}

-proj.android-studio/app/jni/Android.mk LOCAL_SRC_FILESにHelloWorldScene2.cppを追加

LOCAL_SRC_FILES := hellocpp/main.cpp \
                  ../../../Classes/AppDelegate.cpp \
                  ../../../Classes/HelloWorldScene.cpp \
