There is a nice solution in Android from now on : HorizontalGridView.

1. Gradle dependency

dependencies {
    compile 'com.android.support:leanback-v17:23.1.0'
}

2. Add it in your layout

your_activity.xml

3. Layout grid element

Create a layout for your grid element ( grid_element.xml ). I have created a simple one with only one button in it.

4. Create an adapter

Highly inspired by this link : https://gist.github.com/gabrielemariotti/4c189fb1124df4556058

public class GridElementAdapter extends RecyclerView.Adapter{

    private Context context;
    private List elements;

    public GridElementAdapter(Context context){
        this.context = context;
        this.elements = new ArrayList();
        // Fill dummy list
        for(int i = 0; i < 40 ; i++){
            this.elements.add(i, "Position : " + i);
        }
    }

    public static class SimpleViewHolder extends RecyclerView.ViewHolder {
        public final Button button;

        public SimpleViewHolder(View view) {
            super(view);
            button = (Button) view.findViewById(R.id.button);
        }
    }

    @Override
    public SimpleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        final View view = LayoutInflater.from(this.context).inflate(R.layout.grid_element, parent, false);
        return new SimpleViewHolder(view);
    }

    @Override
    public void onBindViewHolder(SimpleViewHolder holder, final int position) {
        holder.button.setText(elements.get(position));
        holder.button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(context, "Position =" + position, Toast.LENGTH_SHORT).show();
            }
        });
    }

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

    @Override
    public int getItemCount() {
        return this.elements.size();
    }
}

5. Initialize it in your activity :

private HorizontalGridView horizontalGridView;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_activity);
    horizontalGridView = (HorizontalGridView) findViewById(R.id.gridView);
    GridElementAdapter adapter = new GridElementAdapter(this);

    horizontalGridView.setAdapter(adapter);
}
