如何使ListView可水平滚动(Xamarin.Android)？

public class HorizontalListView : ListView
{
    public HorizontalListView(Context context) : base(context)
    {
    }

    public HorizontalListView(Context context, IAttributeSet attrs) : base(context, attrs)
    {
    }

    public HorizontalListView(Context context, IAttributeSet attrs, int defStyleAttr) : base(context, attrs, defStyleAttr)
    {
    }

    protected override void OnMeasure(int widthMeasureSpec, int heightMeasureSpec)
    {
        int expandSpec = MeasureSpec.MakeMeasureSpec(int.MaxValue >> 2, MeasureSpecMode.AtMost);
        base.OnMeasure(expandSpec, heightMeasureSpec);
    }
}

<com.example.app.HorizontalListView
    android:id="@+id/horizontalListView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" />
