请专注于适配器，因为我想对如何在适配器中显示数据提出建议。

user.json

{
  "UserDetails":
  [
    {
      "firstName" : "KP","lastName" : "xyz","location" : "goa","websites" : [
        {
          "description" : "work","URL" : "digitalocean"
        },{
          "description" : "tutorials","URL" : "digitalocean/community/tutorials"
        }
      ],"socialMedia" : [
        {
          "description" : "twitter","link" : "twitter/digitalocean"
        },{
          "description" : "facebook","link" : "facebook/DigitalOceanCloudHosting"
        }
      ]
    },{
      "firstName" : "NP","lastName" : "ABC","location" : "Shimla","link" : "facebook/DigitalOceanCloudHosting"
        },{
          "description" : "github","link" : "github/digitalocean"
        }
      ]
    }
