Hello Friends.

This is blog about create your own PhotoGallery in Android.

Below is you Adapter class, it's look like....

public class ImageAdapter extends BaseAdapter {
        private LayoutInflater mInflater;

        public ImageAdapter() {
            mInflater = LayoutInflater.from(getActivity());
        }

        public int getCount() {
            return count;
        }

        public Object getItem(int position) {
            return position;
        }

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

        public View getView(final int position, View convertView, ViewGroup parent) {
            final ViewHolder holder;
            if (convertView == null) {
                holder = new ViewHolder();
                convertView = mInflater.inflate(R.layout.row_photo_grid, null);
                holder.imageview = (ImageView) convertView.findViewById(R.id.row_photo_grd_image);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }

            try {
                setBitmap(holder.imageview, ids[position]);
            } catch (Throwable e) {
            }
            holder.id = position;
            holder.imageview.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                    loadNextFragment(arrPath[position]);
                }
            });
            return convertView;
        }
    }

 public String getImagePath(Context inContext, Bitmap inImage) {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
        return getRealPathFromURI(Uri.parse(path));
    }

public String getRealPathFromURI(Uri uri) {
        Cursor cursor = getActivity().getContentResolver().query(uri, null, null, null, null);
        cursor.moveToFirst();
        int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
        return cursor.getString(idx);
    }

 private void fillAdapter() {
        final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
        final String orderBy = MediaStore.Images.Media._ID;

        int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);
        this.count = imagecursor.getCount();
        this.arrPath = new String[this.count];
        ids = new int[count];
        for (int i = 0; i < this.count; i++) {
            imagecursor.moveToPosition(i);
            ids[i] = imagecursor.getInt(image_column_index);
            int dataColumnIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA);
            arrPath[i] = imagecursor.getString(dataColumnIndex);
        }
    }

private void setBitmap(final ImageView iv, final int id) {

        new AsyncTask<Void, Void, Bitmap>() {
            @Override
            protected Bitmap doInBackground(Void... params) {
                return MediaStore.Images.Thumbnails.getThumbnail(getActivity().getApplicationContext().getContentResolver(), id, MediaStore.Images.Thumbnails.MICRO_KIND, null);
            }

            @Override
            protected void onPostExecute(Bitmap result) {
                super.onPostExecute(result);
                iv.setImageBitmap(result);
            }
        }.execute();
    }
