I have a layout that includes two buttons that a user can select to be in either "Browse Mode" or "Search Mode". They work perfect, but my question is this. Is there a way to make the button appear pressed in and a different colour to signal which mode they are in? In other words, if they are in browse mode the button should appear pressed in and lets say green. The search button would appear normal. When the user presses the "Search" button, it would then appear pressed in and green and the "Browse" button would return to normal? I know how to do this in most situations, like between layouts etc, but I can't seem to figure out an easy way during a simple mode change as the layout is static.
