title: Empty NumberPicker in android API 11
body: <p>I created NumberPicker but it comes up empty and I cant click anything else than textfield where is this "0" and when I do that keypad pops up. Here is picture to clarify what I mean.</p>
  
  <p>Picture:

  <p>Here is the code that I use to create dialog:</p>
  
  <pre><code>Dialog dialog = new Dialog(SettingsActivity.this);
  dialog.setContentView(R.layout.draws_dialog);
  dialog.show();
  </code></pre>
  
  <p><code>SettingsActivity</code> is the activity where I create and show this dialog.</p>
  
  <p>and here is the xml of my dialog:</p>
  
  
  
  <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="wrap_content" 
   android:layout_height="wrap_content"&gt;
  
      &lt;NumberPicker
          android:id="@+id/numberPicker1"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_alignParentLeft="true"
          android:layout_alignParentTop="true" /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>so any Idea what am I doing wrong here?</p>
