java.lang.Integer cannot be cast to com.felipecsl.asymmetricgridview.library.model.AsymmetricItem

I am trying to use AsymmetricGridView to implement 3 column view of images; but could not get it to work. Throws me the error mentioned.
Here is my code:

public class HomeActivity extends AppCompatActivity {

private AsymmetricGridView listView;
private ImageAdapter adapter;

private Cursor cursor;
/*
 * Column index for the Thumbnails Image IDs.
 */
private int columnIndex;

@Override
protected void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);

    listView = (AsymmetricGridView) findViewById(R.id.listView);

    // Choose your own preferred column width
    listView.setRequestedColumnWidth(dpToPx(120, this));
    listView.setAllowReordering(true);

    // 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 = getContentResolver().query(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
            projection, // Which columns to return
            null,       // Return all rows
            null,
            MediaStore.Images.Thumbnails._ID);
    // Get the column index of the Thumbnails Image ID
    columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);


    final List<AsymmetricItem> items = new ArrayList<>();

    // initialize your items array
    adapter = new ImageAdapter(this);
    AsymmetricGridViewAdapter asymmetricAdapter =
            new AsymmetricGridViewAdapter<>(this, listView, adapter);
    listView.setAdapter(asymmetricAdapter);

    // Set up a click listener
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView parent, View v, int position, long id) {
            // Get the data location of the image
            String[] projection = {MediaStore.Images.Media.DATA};
            cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                    projection, // Which columns to return
                    null,       // Return all rows
                    null,
                    null);
            columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
            cursor.moveToPosition(position);
            // Get image filename
            String imagePath = cursor.getString(columnIndex);
            // Use this path to do further processing, i.e. full screen display

            //Indent for passing string file path to edit activity
        }
    });

}

/**
 * Adapter for our image files.
 */
private class ImageAdapter extends BaseAdapter {
    private Context context;

    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));
        } else {
            picturesView = (ImageView) convertView;
        }
        return picturesView;
    }
}
