And the code of my java file is :

CategoryArray = CW.CategoryWebservice("http://www.balajeebazaar.com/RestServiceImpl.svc/categorydetails");

for(int i = 0;i<=CategoryArray.length()-1;i++){
            try {
                Log.v("Categories :- ", CategoryArray.getString(i)+"");
                String[] val = new String[3];
                val = CategoryArray.getString(i).split(",");
                Log.v("val[0] :  ", val[0]);
                Log.v("val[1]  :", val[1]);
                CategoryList.add(i, val[0]+" "+val[1]);
                val = null;
                Log.v("CATEGORY LIST", CategoryList.get(i).toString());
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        //CategoryList.size();
        adapter = new CategoryListAdapter(CategoryActivity.this, CategoryList);

The code for my CategoryListAdapter class is :

public class CategoryListAdapter extends BaseAdapter {
    private Activity activity;
    // private String[] data;
    private ArrayList<String> CategoryList = new ArrayList<String>();
    private static LayoutInflater inflater = null;

    // public ImageLoader imageLoader;

    public CategoryListAdapter(Activity a, ArrayList<String> categorylist) {
        activity = a;
        // data = d;
        inflater = (LayoutInflater) activity
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        CategoryList = categorylist;
        // imageLoader=new ImageLoader(activity.getApplicationContext());
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return CategoryList.size();
    }

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

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    public static class ViewHolder {
        public TextView text;
        public ImageView image;
    }

Code Edit :

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        View vi;
        ViewHolder holder;
        if (convertView == null) {
            vi = new View(activity);
            LayoutInflater inflater = activity.getLayoutInflater();
            vi = inflater.inflate(R.layout.item, null, true);
            holder = new ViewHolder();
            holder.text = (TextView) vi.findViewById(R.id.text);
            holder.image = (ImageView) vi.findViewById(R.id.image);
            vi.setTag(holder);
        } else {
            vi = convertView;
            holder = (ViewHolder) vi.getTag();
            holder.text.setText(CategoryList.get(position).toString());
            holder.image.setTag(R.drawable.go_arrow);
        }
        holder.text.setText(CategoryList.get(position).toString());
        holder.image.setTag(R.drawable.go_arrow);
        vi.setTag(holder);
        return vi;
    }
}

Try this CategoryListAdapter replace at yours, and let me know what happen,

EDIT:

   public class CategoryListAdapter extends BaseAdapter {
    private Activity activity;
    // private String[] data;
    private ArrayList<String> CategoryList = new ArrayList<String>();

    public CategoryListAdapter(Activity a, ArrayList<String> categorylist) {
        activity = a;
        CategoryList = categorylist;

    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return CategoryList.size();
    }

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

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    public static class ViewHolder {
        public TextView text;
        public ImageView image;
    }

     @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        View vi;
        ViewHolder holder;
        if (convertView == null) {
            LayoutInflater inflater =getLayoutInflater();
            vi = inflater.inflate(R.layout.item, parent);
            holder = new ViewHolder();
            holder.text = (TextView) vi.findViewById(R.id.text);
            holder.image = (ImageView) vi.findViewById(R.id.image);
            vi.setTag(holder);
        } else{
                  vi = convertView;
                   holder = (ViewHolder) vi.getTag();
                  }
        String texttoappend = CategoryList.get(position);
        Log.v("texttoappend", texttoappend);
        holder.text.setText(CategoryList.get(position).toString());
        holder.image.setTag(R.drawable.go_arrow);
        // imageLoader.DisplayImage(data[position], activity, holder.image);
        return vi;
    }
}
