cpp通过Message掉java

1.文件引入

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

2.按钮部分代码

void HelloWorld::menuCloseCallback(CCObject* pSender) {bool isHave;const char* msgRet;JniMethodInfo minfo;const char* fileName = "testWei";isHave = JniHelper::getStaticMethodInfo(minfo, "org/test/MyStatic","sendWeibo", "(Ljava/lang/String;)Ljava/lang/String;");if (isHave) {jstring jTitle = minfo.env->NewStringUTF(fileName);jobject obj = minfo.env->CallStaticObjectMethod(minfo.classID,minfo.methodID, jTitle);jstring jRet = (jstring) obj;msgRet = (minfo.env)->GetStringUTFChars(jRet, NULL);}}

3.java 有static类方法

public class MyStatic {private static Handler mHandler;public static final int SHOW_DIALOG = 0x0001;public static void init(Handler handler) {MyStatic.mHandler = handler;}public static String sendWeibo(String pCon) {System.out.println("sendWeibo  :  " + pCon);Message msg = mHandler.obtainMessage(); // 发送给那个类msg.what = MyStatic.SHOW_DIALOG;msg.sendToTarget();return "";}}

4.java接受3发过来的消息代码

onCreate..里

MyStatic.init(mHandler);

public Handler mHandler = new Handler() {@Overridepublic void handleMessage(Message msg) {switch (msg.what) {case MyStatic.SHOW_DIALOG:System.out.println("SHOW_DIALOG  SHOW_DIALOG");break;}}};
