显示/隐藏列表视图项目onclick

Question

我ListView显示行“标题”，我希望可以点击打开“正文”并再次点按它。每个人都可以想象它（就像Expandable ListView）。所以我不想使用Expandable ListView但不能使我的行的“身体”消失。这是代码：

feedListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapter, final View view, int position, long arg) {             
            LinearLayout body = (LinearLayout) view.findViewById(R.id.lInfo);
            ImageView div = (ImageView) view.findViewById(R.id.divider);

           switch(body.getVisibility()){
                case (View.GONE): {                       
                    body.setVisibility(View.VISIBLE);
                    div.setVisibility(View.VISIBLE);
                    Log.w("body vis",""+body.getVisibility());
                    Log.w("set visible","VISIBLE!");
                }
                break;
               case (View.VISIBLE):{                       
                   body.setVisibility(View.GONE);
                   div.setVisibility(View.GONE);
               }
               break;

              }

        }
    });
}

我的活动布局：

<?xml version="1.0" encoding="utf-8"?>

        </LinearLayout>
        </LinearLayout>

</LinearLayout>
</LinearLayout>

这是我的适配器 getView ：

 public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;
    if (convertView == null) {
        convertView = layoutInflater.inflate(R.layout.contact_item, null);
        holder = new ViewHolder();
        holder.body = (LinearLayout)convertView.findViewById(R.id.lInfo);
        holder.facultyName = (TextView) convertView.findViewById(R.id.fName);
        holder.mAddress = (TextView) convertView.findViewById(R.id.tvAddress);
        holder.mDekanat = (TextView) convertView.findViewById(R.id.tvDekanat);
        holder.mPhone = (TextView) convertView.findViewById(R.id.tvPhone);
        holder.mEmail = (TextView) convertView.findViewById(R.id.tvEmail);
        holder.mSite = (TextView) convertView.findViewById(R.id.tvSite);
        holder.mSiteTwo = (TextView) convertView.findViewById(R.id.tvSiteTwo);
        holder.mEmailTwo = (TextView) convertView.findViewById(R.id.tvEmailTwo);
        holder.mShedule = (TextView) convertView.findViewById(R.id.tvShedule);
        holder.mTime = (TextView) convertView.findViewById(R.id.tvTime);
        holder.mTime1 = (TextView) convertView.findViewById(R.id.tvTime1);
        holder.mTime2 = (TextView) convertView.findViewById(R.id.tvTime2);
        holder.mTime3 = (TextView) convertView.findViewById(R.id.tvTime3);
        holder.mTime4 = (TextView) convertView.findViewById(R.id.tvTime4);
        holder.llShedule = (LinearLayout)convertView.findViewById(R.id.llShedule);
        holder.mShedule1 = (TextView) convertView.findViewById(R.id.tvShedule1);
        holder.mShedule2 = (TextView) convertView.findViewById(R.id.tvShedule2);
        holder.mShedule3 = (TextView) convertView.findViewById(R.id.tvShedule3);
        holder.mShedule4 = (TextView) convertView.findViewById(R.id.tvShedule4);
        holder.mWorkTime = (TextView) convertView.findViewById(R.id.tvWorkTime);
        holder.mDivider = (ImageView) convertView.findViewById(R.id.divider);

// holder.mImage =（ImageView）convertView.findViewById（R.id.imgContact）;

        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();

    }
    ContactItem contactItem = (ContactItem) listData.get(position);
    Typeface font = Typeface.createFromAsset(mContext.getAssets(), "OpenSans-Regular.ttf");
    holder.facultyName.setTypeface(font);
    holder.facultyName.setText(contactItem.getName());
    holder.mEmail.setVisibility(View.GONE);
    holder.mDekanat.setVisibility(View.GONE);
    holder.mPhone.setVisibility(View.GONE);
    holder.mSite.setVisibility(View.GONE);
    holder.mAddress.setVisibility(View.GONE);
    holder.mSiteTwo.setVisibility(View.GONE);
    holder.mShedule.setVisibility(View.GONE);
    holder.mEmailTwo.setVisibility(View.GONE);
    holder.mTime.setVisibility(View.GONE);
    holder.llShedule.setVisibility(View.GONE);
    holder.mWorkTime.setVisibility(View.GONE);
    holder.body.setVisibility(View.GONE);

    return convertView;
}

正如你所看到的，我在我的适配器中将VISIBILITY设置为GONE，然后在OnClick方法中使其可见并且它可以工作！但当我再次点击“标题”时，没有任何反应！在我展示身体后，我该怎么做才能隐藏身体？

您可以使用Expandable Library来实现此目的。它就像ExpandableListview，但您必须为标题和内容设置布局;）
