CustomShapes.java

To create a circle dynamically:

public static ShapeDrawable drawCircle (Context context, int width, int height, int color) {

        ShapeDrawable oval = new ShapeDrawable (new OvalShape ());
        oval.setIntrinsicHeight (height);
        oval.setIntrinsicWidth (width);
        oval.getPaint ().setColor (color);
        oval.setPadding (10,10,10,10);
        return oval;
    }
    
To draw a rectangle dynamically:

public static ShapeDrawable drawRectangle (Context context,int width, int height, int color) {

      ShapeDrawable rect = new ShapeDrawable(new RectShape ());
      rect.setIntrinsicHeight (width);
      rect.setIntrinsicWidth (height);
      rect.getPaint().setColor (color);
      return rect;
  }
  
To draw a Rounded-rectangle dynamically:

 public static ShapeDrawable drawRoundCornerRectange (Context context,int width, int height, float[] outerRadii, int color) {

      ShapeDrawable rndrect = new ShapeDrawable (new RoundRectShape (outerRadii, null, null));
      rndrect.setIntrinsicHeight (width);
      rndrect.setIntrinsicWidth (height);
      rndrect.getPaint ().setColor (color);
      return rndrect;
    }

To create a Gradient drawable dynamically:

  public static GradientDrawable setGradientColors(Context context, int bottomColor, int topColor) {

      GradientDrawable gradient = new GradientDrawable(GradientDrawable.Orientation.BOTTOM_TOP, new int[] {bottomColor, topColor});
      gradient.setShape (GradientDrawable.RECTANGLE);
      //gradient.setCornerRadius(10.f);
      return gradient;

    }
