Android : setBackground in onCreateDrawableState

I have a situation where I need to setBackground of my custom button based on a condition dynamically in onCreateDrawableState. So my code is like this

public class MyButton extends Button  {
public boolean nightMode = false;
private Drawable dayBackground, nightBackgound;
public MyButton(Context context, AttributeSet attrs) {
    super(context, attrs);
    setDuplicateParentStateEnabled(true);
    TypedArray a = context.getTheme().obtainStyledAttributes(
            attrs,
            R.styleable.QITheme,
            0, 0);

    try {
        dayBackground = a.getDrawable(R.styleable.MyTheme_dayBackground);
        nightBackgound = a.getDrawable(R.styleable.MyTheme_nightBackground);
    } finally {
        a.recycle();
    }

}
@Override
protected int[] onCreateDrawableState(int extraSpace) {
    int[] state = super.onCreateDrawableState(extraSpace+1);
    if (CurrentThemeManager.isNightMode()) {
        if(nightBackgound != null)
            setBackground(nightBackgound);
    } else {
        if(dayBackground != null)
            setBackground(dayBackground);
    }
    return state;
}

}

But since setBackground calls onCreateDrawableState indirectly, I am getting StackOverflowError due to infinite recursive calls
