ExpandableList查看墜毀在零個項目情況一組

1：在案例中，如果任何一組有沒有項目，然後墜毀ExpandableList查看墜毀在零個項目情況一組

2：在情況下，如果只有一個組，然後它顯示了在只有一個項目打開該組。

 public class AssignmentCompletedExpandableAdapter extends BaseExpandableListAdapter { 

      private List<String> _listDataHeader; 

      private HashMap<String, List<AssignmentScore>> _listDataChild; 

      public AssignmentCompletedExpandableAdapter(List<String> _listDataHeader, 
                 HashMap<String, List<AssignmentScore>> _listDataChild){ 
       this._listDataHeader = _listDataHeader; 
       this._listDataChild = _listDataChild; 
      } 

      @Override 
      public Object getChild(int groupPosition, int childPosititon) { 

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

      } 

      @Override 
      public long getChildId(int groupPosition, int childPosition) { 
       return childPosition; 
      } 

      @Override 
      public int getChildrenCount(int groupPosition) { 
       return this._listDataChild.size(); 
      } 

      @Override 
      public Object getGroup(int groupPosition) { 
       return this._listDataHeader.get(groupPosition); 
      } 

      @Override 
      public int getGroupCount() { 
       return this._listDataHeader.size(); 
      } 

      @Override 
      public long getGroupId(int groupPosition) { 
       return groupPosition; 
      } 

      @Override 
      public boolean hasStableIds() { 
       return false; 
      } 

      @Override 
      public boolean isChildSelectable(int groupPosition, int childPosition) { 
       return false; 
      } 

      @Override 
      public View getChildView(int groupPosition, int childPosition, boolean isLastChild, 
             View convertView, ViewGroup parent) { 

        if(convertView == null){ 
          convertView = ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)). 
                  inflate(R.layout.layout, null); 

        } 



          Data data = (Data) getChild(groupPosition, childPosition); 
         TaggedView view = TaggedView.getTaggedView(convertView); 

          view .name_textView.setText(data.getName()); 
          view .score_textView.setText(data.getScore()); 


        return convertView; 

      } 

      @Override 
      public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) { 

       if(convertView == null){ 
         convertView = ((LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)). 
                 inflate(R.layout.layoutgroup, null); 
        } 

       TextView lblListHeader = (TextView)convertView.findViewById(R.id.groupname); 
       lblListHeader.setText((String)getGroup(groupPosition)); 

       return convertView; 

      } 

     }

嘗試使用，如果條件或交換機爲例來檢查你的病情 –

匿名，什麼是其標記爲負的問題的呢？ @Itsnotblank當我點擊具有零項的組時它爲getChild去哪裏，如果我把條件我需要重試一個視圖，應該有一個條件，它不會得到點擊，任何提示。 – strike

我認爲你的getChildrenCount應該改變如下，按預期工作。讓我知道這個是否奏效。

@Override 
    public int getChildrenCount(int groupPosition) { 
     return this._listDataChild.get(_listDataHeader.get(groupPosition)).size(); 
    }
