Can someone give a simple snippet code with a custom adapter, document seems to be so complex with little to no explanation

Model Class

`public class ImageModel implements AsymmetricItem {
private int columnSpan;
private int rowSpan;
private int position;
private String img;

public ImageModel(String img) {
this(1, 1, 0);
this.img = img;
}

    public ImageModel(int columnSpan, int rowSpan, int position) {
        this.columnSpan = columnSpan;
        this.rowSpan = rowSpan;
        this.position = position;
    }

    public ImageModel(Parcel in) {
        readFromParcel(in);
    }

    @Override
    public int getColumnSpan() {
        return columnSpan;
    }

    @Override
    public int getRowSpan() {
        return rowSpan;
    }

    public int getPosition() {
        return position;
    }

    @Override
    public String toString() {
        return String.format("%s: %sx%s", position, rowSpan, columnSpan);
    }

    @Override
    public int describeContents() {
        return 0;
    }

    private void readFromParcel(Parcel in) {
        columnSpan = in.readInt();
        rowSpan = in.readInt();
        position = in.readInt();
    }

    @Override
    public void writeToParcel(@NonNull Parcel dest, int flags) {
        dest.writeInt(columnSpan);
        dest.writeInt(rowSpan);
        dest.writeInt(position);
    }

    /* Parcelable interface implementation */
    public final Parcelable.Creator<ImageModel> CREATOR = new Parcelable.Creator<ImageModel>() {
        @Override
        public ImageModel createFromParcel(@NonNull Parcel in) {
            return new ImageModel(in);
        }

        @Override
        @NonNull
        public ImageModel[] newArray(int size) {
            return new ImageModel[size];
        }
    };
}`

My Adapter class

`public class DefaultListAdapter extends BaseAdapter {

    private List<ImageModel> items;

    public DefaultListAdapter(Context context, List<ImageModel> items) {
        this.items = items;
    }

    @Override
    public int getCount() {
        return items.size();
    }

    @Override
    public Object getItem(int position) {
        return items.get(position);
    }

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

    @Override
    public View getView(int position, View view, @NonNull ViewGroup parent) {

        if (view == null) {
            LayoutInflater layoutInflater = LayoutInflater.from(getContext());
            view = layoutInflater.inflate(R.layout.gallery_view_event_creation, null);
        }
        ImageView mImage = (ImageView) view.findViewById(R.id.img);
        ImageUtil.LoadImage(getContext(), items.get(position).img, mImage);
        return view;


    }

    public void appendItem(ImageModel newItems) {
        this.items.add(newItems);
        notifyDataSetChanged();

    }


}
