title: Why does the datepicker add a calendar in my view?
body: <p><br>
  I am starting to learn how to develop on Android. It is pretty straightforward but I'm facing an issue I did not find any mention anywhere...</p>
  
  <p>I have a view :</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"
       android:paddingLeft="16dp"
  android:paddingRight="16dp"
  android:orientation="vertical"&gt;
  
      &lt;EditText
          android:id="@+id/editNomProduit"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:ems="10"
          android:hint="@string/ht_nom_produit" /&gt;
  
  
  
      &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
       android:paddingLeft="16dp"
  android:paddingRight="16dp"
  android:orientation="horizontal"&gt;
  
          &lt;TextView
              android:id="@+id/labelQuantiteProduitEdit"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="@string/labelQuantiteProduitEdit"
              android:textAppearance="?android:attr/textAppearanceMedium" /&gt;
  
  &lt;EditText
          android:id="@+id/editQuantite"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:inputType="number" /&gt;
  
  &lt;Spinner
      android:id="@+id/spinnerUnite"
      android:layout_width="wrap_content"
          android:layout_height="wrap_content"/&gt;
  
      &lt;/LinearLayout&gt;
      &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
       android:paddingLeft="16dp"
  android:paddingRight="16dp"
  android:orientation="horizontal"&gt;
  
          &lt;TextView
              android:id="@+id/labeDateAchatProduitEdit"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="@string/labelDateAchatProduitEdit"
              android:textAppearance="?android:attr/textAppearanceMedium" /&gt;
  
          &lt;DatePicker
              android:id="@+id/dpDateAchatProduit"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content" /&gt;
  
  &lt;/LinearLayout&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Which displayed a datepicker. The thing is that the date picker seems to add a Calendar besides the classic rollers for the date picker (see picture). I don't want this view, juste the roller for the date. Am I usign the date picker in the wrong way or is this the orignal behavior ?
   Thanks !</p>
