COCOS2D-X之CPP调用Android函数Demo

希望这篇文章能够给大家带来帮助废话少说直接在COCOS2D-X自带的HelloCpp中添加代码如下:

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) #include <jni.h> #include "jni/JniHelper.h"#endifbool HelloWorld::init(){ CCLayer::init();#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) const char* pStr = "Cpp Call Java Function!!!"; JniMethodInfo MethodInfo; bool BExist    = JniHelper::getStaticMethodInfo(MethodInfo,"mm/nn/oo/HelloCpp","ShowMessageFromNative","(Ljava/lang/String;)V"); if (BExist) {  jstring Str = MethodInfo.env->NewStringUTF(pStr);  MethodInfo.env->CallStaticVoidMethod(MethodInfo.classID,MethodInfo.methodID,Str);  MethodInfo.env->DeleteLocalRef(Str);  MethodInfo.env->DeleteLocalRef(MethodInfo.classID); }#endif return true;}

然后我们修改MK文件在相应的地方分别加上如下语句:

LOCAL_WHOLE_STATIC_LIBRARIES += PluginProtocolStatic$(call import-moudle,plugin/protocols/proj.android/jni)

我们Android中的代码看起来是这样的(只显示我们这里需要关注的)

package mm.nn.oo;public class HelloCpp extends Cocos2dxActivity{ public static Activity mContext; static Handler Statichandler = new Handler() {  @Override public void handleMessage(Message msg)  {   switch (msg.what)   {   case 1:    String StrMsg = (String)msg.obj;    Toast.makeText(mContext,StrMsg,Toast.LENGTH_SHORT).show();    break;   default:    break;   }  }; };  public static void ShowMessageFromNative(String str) {  Message msg = new Message();  msg.what = 1;  msg.obj = str;  Statichandler.sendMessage(msg); }

最后附上本工程下载地址http://t.cn/8sPuK2J那就说到这里了拜拜
