Ok. Sorry if this queshion be here.

I build custom gallery for photos only. I taking photos from sdcard with this class:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public class Photos {
        public static final String PHOTO_BUCKET_NAME =
                Environment.getExternalStorageState().toString() + "/DCIM/Camera";
        public static final int PHOTO_BUCKET_ID = getBucketId(PHOTO_BUCKET_NAME);
 
        public static int getBucketId(String path) {
                return path.toLowerCase().hashCode();
        }
        
        public static List<String> getPhotos(Context context) {
                final String[] projection = {MediaStore.Images.Media.DATA};
                final String selection = MediaStore.Images.Media.BUCKET_ID;
                Cursor c = context.getContentResolver().query(Images.Media.EXTERNAL_CONTENT_URI, projection, selection, null, null);
                List<String> result = new ArrayList<String>(c.getCount());
                if (c.moveToFirst()) {
                        int dataColumn = c.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                        do {
                                String data = c.getString(dataColumn);
                                result.add(data);
                        } while (c.moveToNext());
                }
                c.close();
                return result;
        }

And set adapter to gallery:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

public class ImageAdapter extends BaseAdapter {
            int GalItemBg;
            private Context mContext;
            private List<String> photoList;
 
            public ImageAdapter(Context c) {
                mContext = c;
                photoList = Photos.getPhotosThumbnails(c);
                TypedArray typArray = obtainStyledAttributes(R.styleable.GalleryTheme);
            GalItemBg = typArray.getResourceId(R.styleable.GalleryTheme_android_galleryItemBackground, 0);
            typArray.recycle();
            }
 
            @Override
                public int getCount() {
                return photoList.size();
            }
 
            @Override
                public Object getItem(int position) {
                return position;
            } 
 
            @Override
                public long getItemId(int position) {
                return position;
            }
 
            @Override
                public View getView(int position, View convertView, ViewGroup parent) {
                ImageView i = new ImageView(mContext);
 
                Bitmap bm = BitmapFactory.decodeFile(photoList.get(position));
                i.setImageBitmap(bm);
                i.setLayoutParams(new Gallery.LayoutParams(80,70));
                i.setScaleType(ImageView.ScaleType.FIT_XY);
                i.setBackgroundResource(GalItemBg);
            
                return i;
            }
        }
}
