Hide/Show Navigation item

Make changes in your NavDrawerListAdapter as follow,

public class MyListAdapter extends BaseAdapter {

    Context context;
    ArrayList listMenuItem;
    ArrayList listMenuItem1;
    int hideViewIndex = -1;

    public MyListAdapter(Context context, ArrayList listMenuItem) {
        this.context = context;
        this.listMenuItem = listMenuItem;
        listMenuItem1=new ArrayList(listMenuItem);
    }

    @Override
    public int getCount() {
        return listMenuItem.size();
    }

    @Override
    public Object getItem(int position) {
        return listMenuItem.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    private class ViewHolder
    {
        private ImageView imgLogo;
        private TextView txtItemName;
    }

    public void hideView(int pos)
    {
        listMenuItem.remove(pos);
        notifyDataSetChanged();
    }

    public void showView(int pos)
    {
        listMenuItem.add(pos, listMenuItem1.get(pos));
        notifyDataSetChanged();
    }

    @SuppressLint("InflateParams")
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder viewHolder = null;
        if(convertView == null)
        {
            LayoutInflater myLayoutInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
            convertView = myLayoutInflater.inflate(R.layout.activity_item_list, null);
            viewHolder = new ViewHolder();
            viewHolder.imgLogo = (ImageView) convertView.findViewById(R.id.imgLogo);
            viewHolder.txtItemName = (TextView) convertView.findViewById(R.id.txtItemName);
            convertView.setTag(viewHolder);
        }
        else
        {
            viewHolder = (ViewHolder) convertView.getTag();
        }
        ItemListModel itemListModel = listMenuItem.get(position);
        viewHolder.imgLogo.setImageDrawable(itemListModel.getImageLogo());
        viewHolder.txtItemName.setText(itemListModel.getStrItemName());

        return convertView;
    }

and call this method in activity as follow,

adapter.hideView(2);
//adapter.showView(2);
