public class Sdcard extends Activity {

    //  Cursor used to access the results from querying for images on the SD card.

    private Cursor cursor;

   

     // Column index for the Thumbnails Image IDs.

 

    private int columnIndex;

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_sdcard);

        // Set up an array of the Thumbnail Image ID column we want

        String[] projection = {MediaStore.Images.Thumbnails._ID};

        // Create the cursor pointing to the SDCard

        cursor = managedQuery( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,

                projection, // Which columns to return

                null,       // Return all rows

                null,

                MediaStore.Images.Thumbnails.IMAGE_ID);

        // Get the column index of the Thumbnails Image ID

        columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);

        GridView sdcardImages = (GridView) findViewById(R.id.gridView1);

        sdcardImages.setAdapter(new ImageAdapter(this));

    }

// Image adapter to link images to the gridview 

    private class ImageAdapter extends BaseAdapter {

        public ImageAdapter(Context localContext) {

            context = localContext;

        }

        public int getCount() {

            return cursor.getCount();

        }

        public Object getItem(int position) {

            return position;

        }

        public long getItemId(int position) {

            return position;

        }

        public View getView(int position, View convertView, ViewGroup parent) {

            ImageView picturesView;

            if (convertView == null) {

                picturesView = new ImageView(context);

                // Move cursor to current position

                cursor.moveToPosition(position);

                // Get the current value for the requested column

                int imageID = cursor.getInt(columnIndex);

                // Set the content of the image based on the provided URI

                picturesView.setImageURI(Uri.withAppendedPath(

                        MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + imageID));

                picturesView.setScaleType(ImageView.ScaleType.FIT_XY);

                picturesView.setPadding(10, 10, 10, 10);

                picturesView.setLayoutParams(new GridView.LayoutParams(100, 100));

            }

            else {

                picturesView = (ImageView)convertView;

            }

            return picturesView;

        }

    }

}

Here is the main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
