Answer 1

Aktualisieren Sie Ihre ValueFilter wie unten

private class ValueFilter extends Filter { 
     @Override 
     protected FilterResults performFiltering(CharSequence constraint) { 
      FilterResults results = new FilterResults(); 

      if (constraint != null && constraint.length() > 0) { 
       ArrayList<Contact> filterList = new ArrayList<Contact>(); 
       for (int i = 0; i < stringFilterList.size(); i++) { 
        if ((stringFilterList.get(i).getName().toUpperCase()).contains(constraint.toString().toUpperCase())) { 
         Contact contact = new Contact(stringFilterList.get(i).getName(), stringFilterList.get(i).getPhoneNo(),**stringFilterList.get(i).isSelected**); 
         filterList.add(contact); 


        } 
       } 
       results.count = filterList.size(); 
       results.values = filterList; 
      } else { 
       results.count = stringFilterList.size(); 
       results.values = stringFilterList; 
      } 
      return results; 

     } 

isSelected Wert Ihrer neuen Kontaktliste hinzuzufügen.

Answer 2

Nach Suche, wird die aktuelle Ansicht gleich Position 0 die

contacts.get(position).isSelected() 

Rückkehr wahr oder falsch Mal sehen sein.
