Why is my FloatingActionButton icon black? [duplicate]

Answer 1

You're changing background color of FAB, not the icon color. To change icon color, use:

android:tint

UPDATE

You can also change color programmatically:

Drawable myFabSrc = getResources().getDrawable(android.R.drawable.ic_input_add);
Drawable willBeWhite = myFabSrc.getConstantState().newDrawable();
willBeWhite.mutate().setColorFilter(Color.WHITE, PorterDuff.Mode.MULTIPLY);
myFabName.setImageDrawable(willBeWhite);
