title: Numberpicker: Play sound on scroll
body: <p>I have a numberpicker like below.</p>
  <pre><code>&lt;NumberPicker
      android:layout_width=&quot;0dp&quot;
      android:layout_height=&quot;wrap_content&quot;
      android:layout_gravity=&quot;center_horizontal|center_vertical&quot;
      android:layout_weight=&quot;1.0&quot;
      android:gravity=&quot;center&quot;
      android:padding=&quot;10dp&quot;
      android:textColor=&quot;@color/textcolorprimary&quot;
      android:textSize=&quot;16sp&quot;
      android:theme=&quot;@android:style/Theme.Holo.Light.DarkActionBar&quot; /&gt;
  </code></pre>
  <p>How can I add a short clicking sound when I scroll the numberpicker?
  In IOS, the click sound is standard. Is there something like that in android too?</p>
