cocos2dx 调用java层代码

1.导入头文件

#if(CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)#include <jni.h>#include "android/log.h"#include "platform/android/jni/JniHelper.h"#endif

2.详尽代码

调用非静态方法

JniMethodInfo minfo;//定义Jni函数信息结构体    //getStaticMethodInfo 次函数返回一个bool值表示是否找到此函数    bool isHave = JniHelper::getStaticMethodInfo(minfo,                                                "com/cocos/animation/animation",  //类的路径                                                "rtnActivity",   //方法名                                                "()Ljava/lang/Object;");   //括号里的是参数，后面的是返回值。    jobject jobj;    if (isHave) {       jobj =minfo.env->CallStaticObjectMethod(minfo.classID, minfo.methodID);       CCLog("jobj :%x",jobj);    }    CCLog("正确获取到 jobj");    //    isHave = JniHelper::getMethodInfo(minfo,                                      "com/cocos/animation/animation",  //类的路径                                      "nostaticFun",   //方法名                                      "(Ljava/lang/String;)V");   //括号里的是参数，后面的是返回值。    if (isHave) {    jstring jmsg=minfo.env->NewStringUTF("伊莎贝拉    SB鑫，Sb  Sb  还是SB");         minfo.env->CallVoidMethod(jobj, minfo.methodID,jmsg);    }     CCLog("jni-java函数执行完毕");

java层代码被调用函数

//---- 函数示例之非静态函数调用  //（先获取个对象）  public static Activity actInstance=new animation();//定义单例  public static Object rtnActivity() {      return actInstance;  }  //使用此对象进行调用非静态函数  public void nostaticFun(String str) {      Log.e("Himi", "no static Function is OK - By Himi:str="+str);      StatusesAPI api=new StatusesAPI(animation.accessToken);      /*api.update(str, "90.00","90.00",new RequestListener() {@Overridepublic void onIOException(IOException arg0) {// TODO Auto-generated method stub}@Overridepublic void onError(WeiboException arg0) {// TODO Auto-generated method stub}@Overridepublic void onComplete(String arg0) {// TODO Auto-generated method stub//Toast.makeText(animation.this, "分享成功", Toast.LENGTH_SHORT).show();}});*/            api.upload(str,"/sdcard/33.jpg", "90.00", "90.00", new RequestListener() {@Overridepublic void onIOException(IOException arg0) {// TODO Auto-generated method stub}@Overridepublic void onError(WeiboException arg0) {// TODO Auto-generated method stub}@Overridepublic void onComplete(String arg0) {// TODO Auto-generated method stub//Toast.makeText(animation.this, "分享图片成功", Toast.LENGTH_SHORT).show();}});  }
