title: NumberPicker doesn't work with keyboard
body: <p>In <code>activity_main.xml</code> :</p>
  
  <pre><code>&lt;NumberPicker
          android:id="@+id/numberPicker1"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_below="@+id/textView2"
          android:layout_centerHorizontal="true"
          android:layout_marginTop="30dp" /&gt;
  </code></pre>
  
  <p>In <code>MainActivity.java</code> inside the <code>oncreate</code> :</p>
  
  <pre><code>NumberPicker numberPicker1 = (NumberPicker) findViewById(R.id.numberPicker1);
  numberPicker1.setMinValue(1);
  numberPicker1.setMaxValue(20);
  </code></pre>
  
  <p>When I edit the value with the keyboard, the value that I get programmatically doesn't change, but if I press <code>+</code> then <code>-</code> it works.</p>
  
  <p>How can I make it work without having to press <code>+</code> and <code>-</code>?</p>

  <p><strong>EDIT :</strong></p>
  
  <p>I created a new Project with the code of Melih Altıntaş and it displayed a whole new numberpicker!! (The one where you slide with your finger and can't enter text). Then I compared with my real project and I saw <code>android:theme="@android:style/Theme.NoTitleBar"</code>. I added it in the new project and then the numberpicker became the one I was used to.</p>
