Liste des éléments sélectionnés dans la liste des consommables

Question

Je souhaite récupérer l'élément de données sélectionné dans la liste de sélection non réutilisable. J'ai d'abord obtenu tous les éléments que je les ai sélectionnés ou non ... mais je ne suis pas en mesure d'obtenir les éléments sélectionnés. et affichez-les en tant que parents avec ses enfants.

public class CategoryBaseAdapter extends BaseExpandableListAdapter { 
private Context _context; 
private List<ProfessionEntity> _listDataHeader; 
public static HashMap<ProfessionEntity, List<ProfessionChildEntity>> _listDataChild; 
public static HashMap<Integer, boolean[]> mChildCheckStates; 
    private Map<ProfessionEntity, List<ProfessionChildEntity>> selectedItems; 
public CategoryBaseAdapter(Context context, 
     List<ProfessionEntity> listDataHeader, 
     HashMap<ProfessionEntity, List<ProfessionChildEntity>> listChildData) { 
    this._context = context; 
    this._listDataHeader = listDataHeader; 
    this._listDataChild = listChildData; 
    selectedItems = new HashMap<ProfessionEntity,List<ProfessionChildEntity>>(); 
} 
public Map<ProfessionEntity, List<ProfessionChildEntity>> getSelectedItems() { 
    return selectedItems; 
} 
public boolean isSelected(int groupPosition, int childPosition){ 
    ProfessionEntity group = _listDataHeader.get(groupPosition); 
    ProfessionChildEntity child = getChild(groupPosition,childPosition); 
    List<ProfessionChildEntity> sel = selectedItems.get(group); 
    return sel != null && sel.contains(child); 
} 
public void toggleSelection(int groupPosition, int childPosition){ 
    ProfessionEntity group = _listDataHeader.get(groupPosition); 
    ProfessionChildEntity child = getChild(groupPosition,childPosition); 

    List<ProfessionChildEntity> sel = selectedItems.get(group); 
    if (sel == null){ 
     sel = new ArrayList<ProfessionChildEntity>(); 
     selectedItems.put(group, sel); 
    } 

    if (sel.contains(child)) 
     sel.remove(child); 
    else 
     sel.add(child); 

} 

@Override

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

Dans la méthode getGroupView() vous devriez essayer ceci:

@Override 
     public View getGroupView(int groupPosition, boolean isExpanded, 
       View convertView, ViewGroup parent) { 
     GroupHolder groupHolder; 
      String headerTitle = getGroup(groupPosition).getDecription(); 
      if (convertView == null) { 
       LayoutInflater infalInflater = (LayoutInflater) this._context 
         .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       convertView = infalInflater.inflate(R.layout.group_item, null); 
       groupHolder = new GroupHolder(); 
       groupHolder.lblListHeader = (TextView) convertView 
        .findViewById(R.id.groupTextView); 
       groupHolder.grpCheckBox = (CheckBox) convertView 
        .findViewById(R.id.groupCheckBox); 
     convertView.setTag(groupHolder); 
      } 
     else 
     { 
     groupHolder = (GroupHolder) convertView.getTag(); 
     } 

     groupHolder.grpCheckBox.setOnClickListener(new View.OnClickListener() 
     { 

       @Override 
       public void onClick(View v) 
       { 
        new onCheckBoxClick() 
        { 

         @Override 
         public void OnCheckClick(boolean isChecked) 
         { 
          groupHolder.grpCheckBox.setChecked(isChecked); 
         } 
        }; 
       } 
      }); 
      groupHolder.lblListHeader.setText(headerTitle); 
// you can get data from your modal class i.e.ProfessionEntity class which you have to show check box checked or not checked the following line is for your understanding.   
groupHolder.grpCheckBox.setChecked(groupHolder.grpCheckBox.getChecked());  

      return convertView; 
     } 

     private class GroupHolder 
     { 
       TextView lblListHeader 
       CheckBox grpCheckBox; 

     } 

     private interface onCheckBoxClick 
     { 
       void OnCheckClick(boolean isChecked); 
     }
