my list didn't show on android

I created list, in unity editor works, but didn't on android. my script to show data like this :

 private List<Data> listshow = new List<Data>();
 public GameObject Prefab;
 public Transform Parent;
 
 
 public void Showdata()
     {
             for (int i = 0; i < listshow.Count; i++)
             {
                 GameObject tmpObject = Instantiate(Prefab);
 
                 Data tmpData = listshow[i];
 
                 tmpObject.GetComponent<ListScript>().SetData(tmpData.V.ToString());
                 tmpObject.transform.SetParent(Parent);
             }
     }

Data.cs

 class Data
 {
     public double V { get; set; }
 
     public Data(double v)
     {
         this.V = v;
     }
 }
 

ListScript.cs

 public class ListScript : MonoBehaviour {
 public GameObject data;
 
 public void SetData(string data)
     {
 
         this.data.GetComponent<Text>().text = data;
 
     }
 }
