Cocos2d-x通过Jni实现Cocos2d-x界面跳转到新的Activity

废话不多说，直接上源码

1、Java层

1）首先在org.cocos2dx.cpp目录下添加新类UserInfoActivity.java，该类自行定义即可，代码如下：

package org.cocos2dx.cpp;

import com.pactera.jni.R;//注意路径
import android.app.Activity;  
import android.os.Bundle;  
import android.widget.TextView;  
import android.content.Intent;  
public class UserInfoActivity extends Activity  
{  
    @Override  
    protected void onCreate(Bundle savedInstanceState)  
    {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.userinfo);

        Intent intent = getIntent();  
        String string = intent.getStringExtra("name");  
        
        TextView textView = new TextView(this);  
        textView.setTextSize(40);  
        textView.setText(string);  
          
        setContentView(textView);  
    }  
}

package org.cocos2dx.cpp;

import org.cocos2dx.lib.Cocos2dxActivity;
import org.cocos2dx.lib.Cocos2dxGLSurfaceView;
import android.content.Intent;
import android.os.Bundle;

public class AppActivity extends Cocos2dxActivity{
	public static final int SHOW_DIALOG = 0x0001;
	
	protected void onCreate(Bundle savedInstanceState)
	{
		super.onCreate(savedInstanceState);
	}
	//设置OpenGL的相关信息
	public Cocos2dxGLSurfaceView onCreateView() {
        Cocos2dxGLSurfaceView glSurfaceView = new Cocos2dxGLSurfaceView(this);
        // GuideLayer should create stencil buffer
        glSurfaceView.setEGLConfigChooser(5,6,5,16,8);
         
        return glSurfaceView;
    }
	//加载Cocos2d-x的库
	static {
		
		System.loadLibrary("cocos2dcpp");
	}
	public static void Share(){   //Jni的Java层nativa代码，在Jni目录下的test.cpp实现，并被C++调用
		 Intent intent = new Intent();  
         intent.setClass(AppActivity.getContext(),UserInfoActivity.class);  
         intent.putExtra("name","Hello World");  
         AppActivity.getContext().startActivity(intent);  
    }
}

2、Jni层

test.h

#ifndef TEST_H_
#define TEST_H_
extern "C"
{
	//C++调Java的函数接口，该方法在HelloWorldScene中menuCallback函数中使用。
	void Share();
}
#endif

#include "test.h"
#include "cocos2d.h"
#include "platform/android/jni/JniHelper.h"
#include "../../../Classes/JniTest.h"
#include <jni.h>

//#define CLASS_NAME "org/cocos2dx/cpp/JniTestHelper"
#define CLASS_NAMENEW "org/cocos2dx/cpp/AppActivity"
using namespace cocos2d;
extern "C"
{
	void Share()
	{
		bool hasMethod;
		JniMethodInfo t;
		hasMethod = JniHelper::getStaticMethodInfo(t,CLASS_NAMENEW,"Share","()V");
		if(hasMethod)
		{
			log("Share function");
			if(t.methodID)
			{
				t.env->CallStaticVoidMethod(t.classID,t.methodID);
				log("function share() was called");
			}else{
				log("function share was not called");
			}
		}else
		{
			log("function share was not found");
		}
	}
}

3、C++层

void HelloWorld::menuCloseCallback(Ref* pSender)
{
#if(CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)

    Share();
    
#endif
    
#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)
    exit(0);
#endif
}

4、注意事项

#if(CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
#include "../proj.android/jni/hellocpp/test.h"
#endif

5、运行结果
