title: Android listselector not visible in custom listview
body: <p>I have made a custom list having image and textview. On setting the styles, the selector is not visible. The style is invoked using  setTheme(R.style.rose); in create method of Listactivity as the first call. 
  However if no color is used as background (or background line in style is commented) then the orange selector is visible. But not when the background is </p>
