        if(keycode == cc.KeyCode.KEY_ESCAPE) then
            cc.Director:getInstance():endToLua()
        end
end

local listener = cc.EventListenerKeyboard:create()
listener:registerScriptHandler(onKeyPressed, cc.Handler.EVENT_KEYBOARD_PRESSED)
scene:getEventDispatcher():addEventListenerWithSceneGraphPriority(listener, scene)

Answer 1

-- android 中的返回按钮

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)
