本文介绍如何在Cocos2dx项目中集成extensions库并实现控件操作，包括按钮创建与设置，并演示了如何利用CocoStudio UI编辑器进行界面设计。此外，还详细说明了有米广告SDK的集成步骤，包括Java端与C++端的调用方法。

1.解决使用extensions库编译问题

（1）首先在工程解决方案中右键->属性->add existing project->到目录..../cocosed/extensions/proj.win32/libExtensions.vcxproj

(2) 在自己建的project添加新引用，属性->common properities->add new reference.....

(3)在自己建的project 属性->Configuration properties->C/C++->Additional Include Directires->add "$(EngineRoot)"

2.引入库后，加一个按钮代码段如下

#include"cocos-ext.h"
using namespace cocos2d::extension;

<span style="white-space:pre">	</span>auto* nine = Scale9Sprite::create("CloseNormal.png");
	auto* ninedown = Scale9Sprite::create("CloseSelected.png");

	Label *title = Label::create("Touch me!", "Marker Felt", 30);

	auto* ctlbtn = ControlButton::create(title, nine);
	ctlbtn->setBackgroundSpriteForState(ninedown, Control::State::HIGH_LIGHTED);

	ctlbtn->setPosition(Point(200,200));

	this->addChild(ctlbtn);

3.CocoStudio UI 编辑器

（1）在画布加载好控件后，直接Ctrl+E 导出画布，把export中的三个文件放到工程的resource目录下。

（2）导入libCocosStudio.vcxproj 和libGui.vcxproj库，加"$(EngineRoot)\cocos\editor-support",$(EngineRoot)\cocos,$(EngineRoot).

(3)代码注意加的片段

#include"editor-support\cocostudio\CCSGUIReader.h"
#include"ui\CocosGUI.h"
using namespace cocos2d::ui;
using namespace cocostudio;

	auto UI = cocostudio::GUIReader::getInstance()->widgetFromJsonFile("ForLearning_1.ExportJson");
	UI->setPosition(Point(200, 200));
	this->addChild(UI);

4.Cocos2dx添加有米广告

（1）把有米SDK 里面YoumiSdk_v4.10_2014-09-25.jar加进eclipse的lib目录下

（2）Coco2dx 加广告，需要通过JNI来调用java端的方法

java端代码如下

public class AppActivity extends Cocos2dxActivity {
	  	public static AppActivity youmiads ;  
	    protected void onCreate(Bundle savedInstanceState){  
	        super.onCreate(savedInstanceState); 
	        
			/*start:有米广告代码*/
	        youmiads = this;  
	        //最后的 boolean 值为是否开启测试模式，true 为是，false 为否。（上传有米审核及发布到市场版本，请设置为 false）  
	        AdManager.getInstance(this).init("xxxxxxxxx", "xxxxxxxxxxxxx", false);  
			FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.FILL_PARENT,FrameLayout.LayoutParams.WRAP_CONTENT);
			layoutParams.gravity = Gravity.BOTTOM | Gravity.RIGHT;
			AdView adView = new AdView(this, AdSize.FIT_SCREEN);
			this.addContentView(adView, layoutParams);
			adView.setAdListener(new AdViewListener() {
				@Override
				public void onSwitchedAd(AdView arg0) {
					Log.d("AppActivity", "onSwitchedAd");
				}
				@Override
				public void onReceivedAd(AdView arg0) {
					Log.d("AppActivity", "onReceivedAd");

				}
				@Override
				public void onFailedToReceivedAd(AdView arg0) {
					Log.d("AppActivity", "onFailedToReceivedAd");
				}
			}); 
	          
	        SpotManager.getInstance(this).loadSpotAds();  
	        //设置展示超时时间，加载超时则不展示广告，默认0，代表不设置超时时间  
	        SpotManager.getInstance(this).setSpotTimeout(5000);// 设置5秒  
	        SpotManager.getInstance(this).setShowInterval(20);// 设置20秒的显示时间间隔     
	        /*end:有米广告代码*/
	    }  
	
	    public static Object getActivity(){  
	        System.out.println("object");  
	        return youmiads;  
	    }  
	      
	    public void showAds(){  
	    	Log.d("AppActivity","show ads");
			/*start：有米广告*.*/
			SpotManager.getInstance(this).showSpotAds(
					this, new SpotDialogListener() {
						@Override
						public void onShowSuccess() {
							Log.d("AppActivity", "onShowSuccess");
						}

						@Override
						public void onShowFailed() {
							Log.d("AppActivity", "onShowFailed");
						}

						@Override
						public void onSpotClosed() {
							Log.e("AppActivity", "onSpotClosed");
						}

					});
			//end：有米广告*/
	        //SpotManager.getInstance(this).showSpotAds(this);  
	    }  
	      
	    public void missionads(){  
	        SpotManager.getInstance(this).disMiss(true);  
	    }  
	    @Override  
	    protected void onStop(){  
	        SpotManager.getInstance(this).disMiss(true);
	        super.onStop();   
	    }  
}

(3) cocos2dx端C++代码调用

#if(CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
#include<jni.h>
#include"platform/android/jni/JniHelper.h"
#define CLASS_NAME "org.cocos2dx.cpp.AppActivity"
#define DEBUG 1
#endif

void AppDelegate::showAds()
{

#if(CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)

		JniMethodInfo minfo;
		bool isHava;
#ifdef DEBUG
{
	isHava = JniHelper::getStaticMethodInfo(minfo,"org.cocos2dx.cpp.AppActivity", "getJavaActivity", "()Ljava/lang/object");
	jobject activityObj;
	if(isHava)
	{
		activityObj = minfo.env->CallStaticObjectMethod(minfo.classID, minfo.methodID);
	}
	isHava = JniHelper::getMethodInfo(minfo, "org.cocos2dx.cpp.AppActivity", "showAds","()V");
	if(isHava)
	{
		minfo.env->CallVoidMethod(minfo.classID, minfo.methodID);
	}
}
#endif
#endif
}
