Wie kann ich ExpandableListview sortieren?

Ich verwende eine ExpndableListview mit zwei Arraylist und einem Adapter. Wie kann ich Kinder- und Eltern-Arraylistdaten in absteigender Reihenfolge sortieren?Wie kann ich ExpandableListview sortieren?

1.parent Arraylist

private List<PhoneNumber> listDataHeader = new ArrayList<>();

2.Kind Liste

private HashMap<String, List<SubBalance>> listDataChild = new HashMap<>();

Und ich bin mit Adapter Code in Aktivitätsklasse wie folgt:

 listAdapter = new ExpandableAdapter(getActivity(), listDataHeader, listDataChild, AccountProfileFragment.this);

ExpandableAdapter Code

public class ExpandableAdapter extends BaseExpandableListAdapter implements OnClickListener, OnCheckedChangeListener { 

private Context context; 
private List<PhoneNumber> _listDataHeader; 
private HashMap<String, List<SubBalance>> _listDataChild; 
private DataSwitchListner listner; 
private Activity activity; 
private LoadingDialog loading; 

public ExpandableAdapter(Activity activity, List<PhoneNumber> listDataHeader, HashMap<String, List<SubBalance>> listChildData, DataSwitchListner listner) { 

    loading = LoadingDialog.getInstance(); 
    this.context = activity; 
    this._listDataHeader = listDataHeader; 
    this._listDataChild = listChildData; 
    this.listner = listner; 
    this.activity = activity; 
}

    return this._listDataChild.get(this._listDataHeader.get(groupPosition).getNumber()).get(childPosititon);

dies für Sie vergleichbare Schnittstelle verwenden müssen, und die Liste zu sortieren, bevor – Vickyexpert

@Vickyexpert wie verwende ich vergleichbare Schnittstelle in dem Adapter zuweisen haben mein Code? – Sundar

Sortieren listDataChild Hasmap mit Collections.sort() oder [versuchen Sie dies mit vergleichbar] (http://stackoverflow.com/questions/11647889/sorting-the-mapkey-value-in-descending-order-based-on-the- -Wert) –

public static <K, V extends Comparable<V>> Map<K, V> sortByValues(final Map<K, V> map) { 
    Comparator<K> valueComparator = new Comparator<K>() { 
     public int compare(K k1, K k2) { 
      int compare = map.get(k2).compareTo(map.get(k1)); 
      if (compare == 0) return 1; 
      else return compare; 
     } 
    }; 
    Map<K, V> sortedByValues = new TreeMap<K, V>(valueComparator); 
    sortedByValues.putAll(map); 
    return sortedByValues; 
}
