Question

我正在从JSON检索数据，但是整个数据都显示在我的页面上，但我想以页面方式显示它，例如。第一页1到10，当用户按下按钮时，显示其余记录，我正在工作在那，但无法解决它，在Corona中有任何Paging的概念，或者请就此问题提供帮助，谢谢..

这是我的json数据结构：

My code for displaying JSON data:



 local test=json.decode(event.response)
    local datas=test.data
    for name, users in pairs(datas) do
       for names, usernames in pairs(users ) do
          for tag,value in pairs(usernames) do
           cid=value.customerid
           cname=value.customername
           print(cname)
           print(cid)
          end
       end
    end

这是我的json数据，它将以页面方式显示

{
    "status":"success",
    "data":{
    "marks":[
    {
    "Marks":{
    "first_name":"Amit",
    "last_name":"Sharma",

    "Chemistry":"35",
    "Mathematics":"40"
   }
},
   {

    }
},
    {

    "last_name":"Shukla",
    "country_id":"22",
    "Physics":"50",

    }
},
    {
    "Marks":{

这里有一个关于如何获取JSON数据的提示我只是在这里得到名字和姓氏我只是复制你的json数据并把它放在文本文件名称数据上

local json = require "json"
local txt
local path = system.pathForFile( "data.txt", system.ResourceDirectory )
data = {}
local file = io.open( path, "r" )
if file then
       -- read all contents of file into a string
       txt = file:read( "*a" )
       io.close( file ) -- close the file after using it
end

local t = json.decode (txt)



for i = 1, table.getn(t["data"]["marks"]), 1 do

print(t["data"]["marks"][i]["Marks"]["first_name"])
print(t["data"]["marks"][i]["Marks"]["last_name"])


end

上面的示例代码只是将打印件转储到控制台。我假设最后你想在屏幕上显示它。我建议使用widget.newTableView（）让系统为你处理滚动。
