Create layer list with rounded corners programmatically

Question

I am currently trying to convert the following XML to be created programmatically so that I can set the top corners and bottom corners as needed throughout my project. It is

You're looking for LayerDrawable's setLayerInset in order to be able to set one rectangle above the other.

See below:

float radius = 5.0f;

float[] m_arrfTopHalfOuterRadii = 
    new float[] {radius, radius, radius, radius, 0, 0, 0, 0};
float[] m_arrfBottomHalfOuterRadii = 
    new float[] {0, 0, 0, 0, radius, radius, radius, radius};

int m_nTopColor = Color.BLUE;
int m_nBottomColor = Color.CYAN;

int m_nCellHeight = 40;

public Drawable drawbg()
{
    RoundRectShape top_round_rect = 
        new RoundRectShape(m_arrfTopHalfOuterRadii, null, null);
    ShapeDrawable top_shape_drawable = new ShapeDrawable(top_round_rect);
    top_shape_drawable.getPaint().setColor(m_nTopColor); 

    RoundRectShape bottom_round_rect = 
        new RoundRectShape(m_arrfBottomHalfOuterRadii, null, null);
    ShapeDrawable bottom_shape_drawable = new ShapeDrawable(bottom_round_rect);
    bottom_shape_drawable.getPaint().setColor(m_nBottomColor);

    Drawable[] drawarray = {top_shape_drawable, bottom_shape_drawable};
    LayerDrawable layerdrawable = new LayerDrawable(drawarray);

    int _nHalfOfCellHeight = m_nCellHeight/2; 
    layerdrawable.setLayerInset(0, 0, 0, 0, _nHalfOfCellHeight); //top half
    layerdrawable.setLayerInset(1, 0, _nHalfOfCellHeight, 0, 0); //bottom half

    return layerdrawable;
}
