Programmatically change color of shape in layer list

Question

How can I programmatically change the color (#000000) of a shape in a layer list?

Here is my layer list:

Answer 1

     // Give id
        
             // CHANGE THIS COLOR
        
    
    
        
            
        
    

Then in you code just add

LayerDrawable layerDrawable = (LayerDrawable) getResources()
            .getDrawable(R.drawable.my_drawable);
GradientDrawable gradientDrawable = (GradientDrawable) layerDrawable
            .findDrawableByLayerId(R.id.gradientDrawble);
gradientDrawable.setColor(color); // change color

Update Oct-2016

getDrawable() is now deprecated, you should use ContextCompat.getDrawable(context, color) instead.

Beside, if you get the LayerDrawable by findDrawableByLayerId(), then you had to call view.setBackground(layerDrawable) for this to take effect. Alternatively, instantiating the layerDrawable by view.getBackground() also worked.
