Hello I have an imagebutton linearButton which has a background drawable set in the XML. I want to conditionally replace the background within the code, but it never happens! 

Drawable replacer = getResources().getDrawable(R.drawable.replacementGraphic);
linearButton.setBackgroundDrawable(replacer);

This seems to be ineffective, is there a “reload” function for a imagebuttons that I have to call before they change visually?

    The invalidate() method will force a redraw of any view:

    Drawable replacer = getResources().getDrawable(R.drawable.replacementGraphic);
linearButton.setBackgroundDrawable(replacer);
linearButton.invalidate();

    See here for reference.
