Question

Currently, I have a custom list adapter that has some logic that hide/show a certain ImageView in a row depending on a variable.

Initially, the logic works when the app first launches. (ImageView is hidden/shown accordingly).

But once I scroll the screen up and down, eventually, all the row’s ImageView is hidden forever.

Does anyone know how to solve this problem?

here is my adapter:

public View getView(int position, View convertView, ViewGroup parent) {
        View row = convertView;
        PostHolder holder = null;

        if(row == null)
        {
            LayoutInflater inflater = ((Activity)context).getLayoutInflater();
            row = inflater.inflate(layoutResourceId, parent, false);

            holder = new PostHolder();
            holder.postThumb = (ImageView)row.findViewById(R.id.post_Thumb);
            holder.postComments = (TextView)row.findViewById(R.id.post_comments);
            holder.postInfo = (TextView)row.findViewById(R.id.item_subtitle);
            holder.postScore = (TextView)row.findViewById(R.id.post_score);
            holder.postTitle = (TextView)row.findViewById(R.id.item_title);
            holder.postThumbHolder = (LinearLayout)row.findViewById(R.id.post_Thumb_holder);
            row.setTag(holder);
        }
        else
        {
            holder = (PostHolder)row.getTag();
        }

        HashMap<String, String> post = data.get(position);

        if(post.get("thumbnail").equals("default") || post.get("thumbnail").equals("self")){
            holder.postThumbHolder.setVisibility(View.GONE);
        }

        holder.postComments.setText(post.get("comments"));
        holder.postInfo.setText(post.get("info"));
        holder.postScore.setText(post.get("score"));
        holder.postTitle.setText(post.get("title"));

        return row;
    }


    static class PostHolder
    {
        LinearLayout postThumbHolder;
        ImageView postThumb;
        TextView postComments;
        TextView postScore;
        TextView postTitle;
        TextView postInfo;      
    }

Answer 1

Set visibility View.VISIBLE to postThumbHolder somewhere. In the else block of your
if (post.get...
clause.
