title: Use special symbol (<, >) in layout design in Android
body: <p>I need two navigation buttons with their texts are <code>&lt;</code> and <code>&gt;</code>. However, the compiler doesn't allow me use those symbols, even if I use <code>\&lt;</code> and <code>\&gt;</code>.</p>
  
  <p>Is there anyway to put these symbol into the XML design file?</p>
