title: Ripple effect on custom navigation drawer
body: <p>I'm developing my first app providing to it the new material look. I'm a bit lost with this so I'm following some tutorials to implement things like Toolbar, Navigation Drawer, etc. I have to say that I'm doing it providing compatibility to pre-lollipop android versions, so I'm using support libraries.</p>
  
  <p>What concers to my question, is that I have just implemented the Navigation Drawer following one of this tutorials and using the following libraries for compatibility:</p>
  
  <pre><code>support.v4.widget.DrawerLayout
  support.v7.widget.RecyclerView
  </code></pre>
  
  <p>I think that the code implementation is too long to put it here, so I'll provide the link to this tutorial, I have done it exactly as is said <a href="http://www.androidhive.info/2015/04/android-getting-started-with-material-design/" rel="noreferrer">here</a>.</p>
  
  <p>My problem is that, when I select one item from the navigation drawer's row, it perfectly opens it correspondant frament, but, it doesn't show any ripple effect, or simply any touch effect, when touching it. Something like this:</p>
  
  <p><img src="https://i.stack.imgur.com/zUyBX.gif" alt="enter image description here"></p>
  
  <p>I have taken a look to some other tutorials, for example, to the one to which belongs the attached gif, to see if they use any method or implementation to provide that efect to the touch, but nothing is implemented to get that effect, just the onclick method.</p>
  
  <p>So, what's wrong with this code, and how could I modify it, or what could I add to get that effect?</p>
