Change color of Floating Action Button from Appcompat 22.2.0 programmatically

Question

I would like to know how to change the Floating Action Button color from the Support library 22.2.0 ? I've tried

button.setBackgroundColor(color); 

but clearly, this changes the drawable of the button and it turns to a square.

Now I wonder how to change the color but just the color, without touching the shape?

Thanks in advance

Answer 1

Maybe late but could help.

 fab.setBackgroundTintList(ColorStateList.valueOf(Color                     .parseColor("#33691E"))); 

and parse the actual color code from a list of colors You can find here

Answer 2

Create a ColorStateList and set it as the background tint:

button.setBackgroundTintList(new ColorStateList(new int[][]{new int[]{0}}, new int[]{color}));
