- 在android系统

local function onKeyReleased(keyCode, event) 
    if keyCode == cc.KeyCode.KEY_ESCAPE then 
     cc.Director:getInstance():endToLua() 
    end 
end 

local listener = cc.EventListenerKeyboard:create() 
listener:registerScriptHandler(onKeyReleased,cc.Handler.EVENT_KEYBOARD_RELEASED) 

local eventDispatcher = self:getEventDispatcher() 
eventDispatcher:addEventListenerWithSceneGraphPriority(listener, scene)
