cocos2d-x lua 使用ListView
version: cocos2d-x 3.6
本文主要讲述:使用Cocos Studio创建ListView,和列表项的模板,代码中通过模板创建列表的每一项,并替换其中的图片文字等。
1. 加载Cocos Studio编辑好的资源
-- //cocos studio 中资源的名字
M.srcLayer = {
["listView"] = "list_view",["btnFriends"] = "button_friends",["btnAround"] = "button_around",}
M.srcListItem = {
["bg"] = "image_bg",["img"] = "image_head",["name"] = "lable_name",["meter"] = "lable_meter",}
function M:loadLayout()
if self.m_resNode then
self.m_resNode:removeSelf()
self.m_resNode = nil
end
self.m_resNode = cc.CSLoader:createNode("ui/layer_test_listview.csb") -- //load your layout csb
assert(self.m_resNode,string.format("ViewBase:createResourceNode() - load resouce node from file \"%s\" Failed",resourceFilename))
self:addChild(self.m_resNode)
local listView = self.m_resNode:getChildByName(M.srcLayer.listView)
end
2. 更新ListView的每一项
function M:refreshListView()
local listView = self.m_resNode:getChildByName(M.srcLayer.listView)
assert(listView,"")
listView:removeAllChildren()
local friendList = {
{["id"]="1234567890",["name"]="testName",["picture"]="test.png"},{["id"]="1234567890",}
for idx,oneFriend in pairs(friendList) do
-- //加载模板项
local oneItem = cc.CSLoader:createNode("ui/layer_test_listview_item.csb")
local imgBg = oneItem:getChildByName(M.srcListItem.bg)
local imgHead = oneItem:getChildByName(M.srcListItem.img)
local lableName = oneItem:getChildByName(M.srcListItem.name)
local lableMeter = oneItem:getChildByName(M.srcListItem.meter)
-- //reset
--imgHead:initWithFileName(oneFriend.picture) --//imgHead是精灵类Sprite
lableName:setString(friendInfo.name)
--lableMeter:setString(tostring(oneFriend.meter))
--//create layout
local listItemLayout = ccui.Layout:create()
listItemLayout:setContentSize(imgBg:getContentSize())
listItemLayout:addChild(oneItem)
oneItem:setPosition(cc.p(listItemLayout:getContentSize().width / 2.0,listItemLayout:getContentSize().height / 2.0))
listItemLayout:setTag(idx)
listView:insertCustomItem(listItemLayout,0)
end
end
