COCOS2D-X之CPP調用Android函數Demo

希望這篇文章能夠給大家帶來協助廢話少說直接在COCOS2D-X內建的HelloCpp中添加代碼如下:

#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID) #include  #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;}

然後我們修改MK檔案在相應的地方分別加上如下語句:

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

我們Android中的代碼看起來是這樣的(只顯示我們這裡需要關注的)

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); }

最後附上本工程http://t.cn/8sPuK2J那就說到這裡了拜拜
