Android ExpandableListView : 하위 뷰의 버튼을 클릭 한 후 그룹에서 하위보기를 제거하거나 숨기기

Question

나는 입니다. 첫 번째 Group의 요소는 Buttons입니다. Button 중 하나를 클릭 한 후 Child보기를 제거하거나 숨기려고합니다. 나는이 코드를 다음과 같이 시도했다.

public class ProfileExpandableAdapter extends BaseExpandableListAdapter{ 

private Context context; 
private ArrayList<ExpandableGroup> groups; 
private ImageLoader imageLoader = AppController.getInstance().getImageLoader(); 
private String type = "update_user_friend", userName = ""; 
private JSONParser jsonParser; 
private String wpedenUrl = "", TAG_SUCCESS = "success"; 

public ProfileExpandableAdapter(Context context, ArrayList<ExpandableGroup> groups, String userName) { 
    this.context = context; 
    this.groups = groups; 
    this.userName = userName; 
    jsonParser = new JSONParser(); 
    wpedenUrl = context.getResources().getString(R.string.site); 
} 

@Override 
public Object getChild(int groupPosition, int childPosition) { 
    ArrayList<ExpandableChild> chList = groups.get(groupPosition).getItems(); 
    return chList.get(childPosition); 
} 

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

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

    final ExpandableChild child = (ExpandableChild) getChild(groupPosition, childPosition); 
    if (convertView == null) { 
     LayoutInflater infalInflater = (LayoutInflater) context 
       .getSystemService(context.LAYOUT_INFLATER_SERVICE); 
     convertView = infalInflater.inflate(R.layout.wpedenyo_profile_expandable_group_child, null); 
    } 
    TextView tv = (TextView) convertView.findViewById(R.id.wpedenyo_profile_group_child); 
    tv.setText(child.getName().toString()); 
    String image = child.getThumbnailUrl(); 
    if(groupPosition == 0){ 
     NetworkImageView notifiedUserImage = (NetworkImageView) convertView.findViewById(R.id.wpedenyo_notified_friend_image); 
     notifiedUserImage.setVisibility(View.VISIBLE); 
     notifiedUserImage.setImageUrl(image, imageLoader); 
     Button confirmButton = (Button) convertView.findViewById(R.id.wpedenyo_profile_button_confirm); 
     confirmButton.setVisibility(View.VISIBLE); 
     Button cancelButton = (Button) convertView.findViewById(R.id.wpedenyo_profile_button_cancel); 
     cancelButton.setVisibility(View.VISIBLE); 

     confirmButton.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       // TODO Auto-generated method stub 
       groups.remove(child); 
       notifyDataSetChanged(); 
      } 
     }); 

     cancelButton.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       groups.remove(child); 
       notifyDataSetChanged(); 
      } 
     }); 
    } 

    return convertView; 
} 

public void removeChild(int groupPosition, int childPosition) { 

    if (getChildrenCount(groupPosition)>0 && getChildrenCount(groupPosition)-1 >= childPosition) 
    { 
     Object task = this.getChild(groupPosition, childPosition); 
     groups.remove(task); 
     this.notifyDataSetChanged(); 
    } 
} 

@Override 
public int getChildrenCount(int groupPosition) { 
    ArrayList<ExpandableChild> chList = groups.get(groupPosition).getItems(); 
    return chList.size(); 
} 

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

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

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

@Override 
public View getGroupView(int groupPosition, boolean isExpanded, 
     View convertView, ViewGroup parent) { 
    ExpandableGroup group = (ExpandableGroup) getGroup(groupPosition); 
    if (convertView == null) { 
     LayoutInflater inf = (LayoutInflater) context 
       .getSystemService(context.LAYOUT_INFLATER_SERVICE); 
     convertView = inf.inflate(R.layout.wpedenyo_profile_expandable_group, null); 
    } 
    TextView tv = (TextView) convertView.findViewById(R.id.wpedenyo_profile_list_header); 
    tv.setText(group.getName()); 
    return convertView; 
} 

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

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

그러나 Button을 클릭 한 후이 Group에서 Child을 제거 두지. 내가 어떻게 할 수 있니? 미리 감사드립니다.

Answer 1

대신 groups.remove(child)는 구현해야한다 (아이들을 얻을 현재 그룹을 해보

ExpandableGroup currentGroup=groups.get(groupPosition);

을

1. 같은 것을 (나는 당신이 여기에 그룹을 제거하려는 생각) getChildren 방법) : currentGroup.getChildren().remove(child);

희망이 있습니다.

Answer 2

collapseGroup()으로 전화해야합니다. 또한 생성자에서 내가 마지막 그룹을 숨길이 경우 귀하의 ExpandableListView

public class YourExapandableAdapter extends BaseExpandableListAdapter { 

    private Context mContext; 
    ExpandableListView mExpandableListView; 
    int mLastExpandedGroupPosition = -1; 

    public YourExapandableAdapter(Context context, ExpandableListView expandableListView) { 
      mContext = context; 
      mExpandableListView = expandableListView; 
    } 

    @Override 
    public void onGroupExpanded(int groupPosition) { 
     super.onGroupExpanded(groupPosition); 
     if(groupPosition != mLastExpandedGroupPosition){ 
       mExpandableListView.collapseGroup(mLastExpandedGroupPosition); 
     } 

     mLastExpandedGroupPosition = groupPosition; 
    } 

이 필요하지만 현재 그룹이든 당신이 원하는 수 있습니다.
