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);
}
}
2）AppActivity.java类
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, 0, 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
jni目录下添加test类的.h和.cpp
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
test.cpp
#include “test.h”
#include “cocos2d.h”
#include “platform/android/jni/JniHelper.h”
#include “../../../Classes/JniTest.h”
#include
//#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
添加平台判断头文件
#if(CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
#include “../proj.android/jni/hellocpp/test.h”
#endif
5、运行结果
