quick-cocos2d-x中Lua调用JAVA

 local btn
    btn = cc.ui.UIPushButton.new()
            :setButtonLabel(cc.ui.UILabel.new({text = "call Java - showAlertDialog()",size = 64}))
            :onButtonClicked(function()
                if device.platform ~= "android" then
                   -- print("please run this on android device")
                    btn:setButtonLabel(cc.ui.UILabel.new({text = "please run this on android device",size = 32}))
                    return
                end

            cc.Director:getInstance():endToLua()
            if device.platform == "windows" or device.platform == "mac" then
                os.exit()
            end
        elseif event.key == "menu" then
            --print("menu")
        end
end)

没啥说的，就是给自己做个记录
