title: Android preferences summary default color?
body: <p>I have installed my app in a real phone, and even though in the emulator all the texts of the
  preferences summaries seem to be in the same color, in the real phone the color is different (some kind of blue... but I guess it depends on the phone's model).</p>
  
  <p>How can I set this color to my custom preference component? 
  (I have implemented my own seek bar, and its summary text color is different from all the other components text color...).</p>
  
  <p>Thanks!</p>
