How to modify color of a drawable programatically

Hi I have a shape drawable in xml and it is used as background of a view. Its color needs to be changed in the code depending on conditions.

So I am doing 

  ShapeDrawable d =  (ShapeDrawable) getResources().getDrawable(R.drawable.shape1);

  d.getPaint().setShader(sd1);

but the getDrawable returns a gradient drawable, casting it to ShapeDrawable generates error.

So how can I get shapeDrawable in code and modify its attributes.

This code snippet worked for me:

PorterDuffColorFilter porterDuffColorFilter = new PorterDuffColorFilter(getResources().getColor(R.color.your_color),PorterDuff.Mode.MULTIPLY);

imgView.getDrawable().setColorFilter(porterDuffColorFilter);
imgView.setBackgroundColor(Color.TRANSPARENT)

I have wrote a generic function in which you can pass context, icon is id drawable/mipmap image icon and new color which you need for that icon.

This function returns a drawable.

public static Drawable changeDrawableColor(Context context,int icon, int newColor) {
    Drawable mDrawable = ContextCompat.getDrawable(context, icon).mutate(); 
    mDrawable.setColorFilter(new PorterDuffColorFilter(newColor, PorterDuff.Mode.SRC_IN)); 
    return mDrawable;
} 

changeDrawableColor(getContext(),R.mipmap.ic_action_tune, Color.WHITE);

I was able to fix this by casting as a GradientDrawable instead of ShapeDrawable.

GradientDrawable shape = (GradientDrawable) getResources().getDrawable(R.drawable.shape1);

    shape.setColor(Color);

I used this when I created an activity with a custom style based on the Holo.Dialog theme.

Here is how you can set the color:

d.getPaint().setColor(Color.BLACK);
