Listview Artikel wurden an falscher Stelle hinzugefügt

Ich benutze Listview mit dynamischen Artikeln.Es speichert in falscher Ort (Das bedeutet 1. Artikel zeigt in dritten Artikel, zweiter Artikel zeigt in 5. Artikel, etc.) .Ich weiß nicht, wie zu lösen dieses. Ich habe den relevanten Code hinzugefügt. Bitte überprüfen Sie es.Listview Artikel wurden an falscher Stelle hinzugefügt

in der Größenordnung Volley Antwort Basierend Ich habe das Recht zeigen, ID für Listview.It ta kes falsche Reihenfolge.

Lassen Sie mich wissen, warum es an der falschen Stelle bestellt und wie man das löst.Vielen Dank.

TLDR: Verwenden Sie Arraylist statt List:

private ArrayList<UpcomingGoalItems> items;

Die ArrayAdapters Ich benutze neigen wie folgt aussehen:

(der Arraylist < String> Namen ist eine Arraylist aus den Namen der Arraylist erstellt < Aufgabe>)

public class ArrayAdapterTask extends ArrayAdapter<String> { 

    private final Context context; 
    private int layoutId; 
    private ArrayList<Task> tasks; 

    public ArrayAdapterTask(Context context, ArrayList<String> names, ArrayList<Task> tasks, int layoutId) { 
     super(context, layoutId, names); 

     this.context = context; 
     this.tasks = null; 
     this.tasks = tasks; 
     this.layoutId = layoutId; 
    } 

    @Override 
    public View getView(int position, View view, ViewGroup parent) { 
     // Do stuff with the tasks.get(position) 
    } 
}
