Question

In my application I am trying change background color for each listView item. And for that I am using shapes which in layer-list. Here is my code

drop_shadow.xml

Answer 1

They are both a subclass of Drawable, so you can't cast them to each other, only to their parent classes.

Answer 2

you can create gradient drawable dynamically.. use below class

    import android.graphics.drawable.GradientDrawable;

    public class SomeDrawable extends GradientDrawable {

    public SomeDrawable(int pStartColor, int pCenterColor, int pEndColor, int pStrokeWidth, int pStrokeColor, float cornerRadius) {
        super(Orientation.BOTTOM_TOP,new int[]{pStartColor,pCenterColor,pEndColor});
        setStroke(pStrokeWidth,pStrokeColor);
        setShape(GradientDrawable.RECTANGLE);
        setCornerRadius(cornerRadius);
    }
 }

and use this class as below

SomeDrawable drawable = new SomeDrawable(Color.parseColor("Start Color Code"),Color.parseColor("Center Color Code"),Color.parseColor("End Color Code"),1,Color.BLACK,00);
yourLayout.setBackgroundDrawable(drawable);

Answer 3

i guess it's better to use separacte colors.xml file for the color of the shape, and use tag, you can delete the .

after all your shape both is the same which is rectangle.

previously i got the same error because i'm using and inside the same xml.
