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

-- call Java method
local javaClassName = "org/cocos2dx/lua/AppActivity"
local javaMethodName = "showAlertDialog"
local javaParams = {
"How are you ?",
"I'm great !",
function(event)
local str = "Java method callback value is [" .. event .. "]"
btn:setButtonLabel(cc.ui.UILabel.new({text = str, size = 32}))
end
}
local javaMethodSig = "(Ljava/lang/String;Ljava/lang/String;I)V"
luaj.callStaticMethod(javaClassName, javaMethodName, javaParams, javaMethodSig)
end)
:align(display.CENTER, display.cx, display.cy)
:addTo(self)

btn:setKeypadEnabled(true)
btn:addNodeEventListener(cc.KEYPAD_EVENT, function (event)
dump(event)
local str = "event.key is [ " .. event.key .. " ]"
btn:setButtonLabel(cc.ui.UILabel.new({text = str, size = 32}))
if event.key == "back" then
--print("back")
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
