         Log.i("id", ""+suggestion_topics_model.getWinner());
         //Log.i("inside adapter", suggestion_topics_model.getCreatedDate());
        /* if (suggestion_topics_model.getWinner()==position) {

Try the following code:

public class SuggestionForumTopicAdapter extends BaseAdapter{
    private ArrayList<SuggestionTopicsModel> _suggestionlistData;
    private LayoutInflater layoutInflater;
    SuggestionTopicsModel suggestion_topics_model;
    private Context _context;
    RelativeLayout relative_layout;
    public SuggestionForumTopicAdapter(Context context,ArrayList<SuggestionTopicsModel> listData){
        _suggestionlistData = listData;
        _context = context;
    }
    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return _suggestionlistData.size();
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return _suggestionlistData.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        ViewHolder holder;
        if (layoutInflater == null)
            layoutInflater = (LayoutInflater) _context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        if(convertView == null){
            convertView = layoutInflater.inflate(R.layout.suggestion_custom_dispplay, null);
            holder = new ViewHolder();
            holder.suggestionPostName = (TextView) convertView.findViewById(R.id.suggestionPostName);
            holder.totalnumberofsuggest = (TextView) convertView.findViewById(R.id.totalnumberofsuggest);
            holder.dateofcreate = (TextView) convertView.findViewById(R.id.dateofcreate);
            holder.winnername=(TextView) convertView.findViewById(R.id.winner_name);

            holder.relativeLayout=(RelativeLayout) convertView.findViewById(R.id.winner_layout);

            convertView.setTag(holder);
        }else{
            holder = (ViewHolder) convertView.getTag();
        }
        suggestion_topics_model = (SuggestionTopicsModel) _suggestionlistData.get(position);

         holder.suggestionPostName.setText(suggestion_topics_model.getSuggestionText());

         //Log.i("inside adapter", suggestion_topics_model.getSuggestionText());

         holder.totalnumberofsuggest.setText(Integer.toString(suggestion_topics_model.getTopicsSuggestionCount()));

         //Log.i("inside adapter", suggestion_topics_model.getSuggestionTopicId());

         holder.dateofcreate.setText(suggestion_topics_model.getCreatedDate());


         Log.i("id", ""+suggestion_topics_model.getWinner());
         //Log.i("inside adapter", suggestion_topics_model.getCreatedDate());
        /* if (suggestion_topics_model.getWinner()==position) {
            relative_layout.setVisibility(View.GONE);
            convertView.setClickable(false);
            }*/
         if (suggestion_topics_model.getDispplayname()==null) {
             Log.i("name", suggestion_topics_model.getDispplayname());
             holder.relativeLayout.setVisibility(View.GONE);
        }else{
             holder.winnername.setText(suggestion_topics_model.getDispplayname());
             holder.relativeLayout.setVisibility(View.VISIBLE);

             Log.i("name", suggestion_topics_model.getDispplayname());
        }
        return convertView;
    }
    static class ViewHolder{

        TextView suggestionPostName;
        TextView totalnumberofsuggest;
        TextView dateofcreate;
        TextView winnername;
        RelativeLayout relativeLayout;
    }
}

every time its going inside the else block how to avoid this — koteswara D K, Jan 12 '16 at 07:54
please try the amended code. It will be going into the else block for every row except for the first. It reuses the previous row to render the next, when it does that it passes in the previous convertView as an argument. This isn't the problem. — Richard Poole, Jan 12 '16 at 07:56

for the above problem i found a solution by just changing the following code

 if (suggestion_topics_model.getDispplayname().contains("null")){
             Log.i("name inside the else ", suggestion_topics_model.getDispplayname());
             holder.relativeLayout.setVisibility(View.GONE);
        }else{

             holder.winnername.setText(suggestion_topics_model.getDispplayname());
             holder.relativeLayout.setVisibility(View.VISIBLE);
             Log.i("name", suggestion_topics_model.getDispplayname());

        }
        return convertView;
    }
    static class ViewHolder{

        TextView suggestionPostName;
        TextView totalnumberofsuggest;
        TextView dateofcreate;
        TextView winnername;
        RelativeLayout relativeLayout;
    }
