GridView Menu with icons in Android 2.3
===

i'm developing an app for android and want using GridView build a menu with icons. For this I used already existing solution by http://www.edumobile.org/android/android-beginner-tutorials/draw-menu-in-grid-view/, but the in result the system shows that **mThumbIds** - **cannot be resolved to a variable**,  when i try to declare it as an new local variable, the error is still existing. i'm new in android and maybe making very simple mistake, but i can't solve it by myself. So, any suggestions would be helpful. Here is the code:

        public class ImageAdapter extends BaseAdapter {
    	public ImageAdapter(Context c) {
    		mContext = c;
    	}
    	public int getCount() {
    		return mThumbIds.length;
    	}
    	public Object getItem(int position) {
    		return position;
    	}
    	public long getItemId(int position) {
    		return position;
    	}

	    public View getView(int position, View convertView, ViewGroup parent) {
	    	ImageView imageView;
	        
	        if (convertView == null) {
	        	imageView = new ImageView(mContext);
                imageView.setLayoutParams(new GridView.LayoutParams(45, 45));
                imageView.setAdjustViewBounds(false);
                imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
                imageView.setPadding(8, 8, 8, 8);
            } else {
            	imageView = (ImageView) convertView;
            }
	        
			imageView.setImageResource(mThumbIds[position]);
			return imageView;
	    }

	    private Context mContext;
	    private Integer[] mThumIbs = {
	    		R.drawable.ic_cards, R.drawable.ic_bank,
	    		R.drawable.ic_currency, R.drawable.ic_calc,
	    		R.drawable.ic_banking, R.drawable.ic_call,
	    };
	        
	}
