title: Spinner moves down once receives items
body: <p>I have a simple layout, below is a relevant fragment. It looks exactly as I want it to - as long as the spinner is empty. Once I add items to it (in runtime) - it jumps like half its height down.
  Why?</p>
  
  <pre><code>&lt;ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content" &gt;
  
      &lt;LinearLayout
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"
          android:orientation="vertical" &gt;
  
          &lt;LinearLayout
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical" &gt;
  
              &lt;TableLayout
                  android:layout_width="fill_parent"
                  android:layout_height="wrap_content"
                  android:layout_gravity="top"
                  android:layout_marginTop="10dp" &gt;
  
                  &lt;TableRow
                      android:layout_width="fill_parent"
                      android:layout_height="wrap_content" &gt;
  
                      &lt;TextView
                          android:id="@+id/lbl"
                          style="@style/Label.Plain"
                          android:layout_height="@dimen/button_height"
                          android:layout_marginRight="5dp"
                          android:layout_weight="0"
                          android:gravity="left|center_vertical" /&gt;
  
                      &lt;Spinner
                          android:id="@+id/spinner"
                          style="@style/Spinner"
                          android:background="#ff0000"
                          android:layout_width="fill_parent"
                          android:layout_weight="1" /&gt;
  
                  &lt;/TableRow&gt;
              &lt;/TableLayout&gt;
          &lt;/LinearLayout&gt;
      &lt;/LinearLayout&gt;
  &lt;/ScrollView&gt;
  </code></pre>
  
  <p>And this is "Spinner" style:</p>
  
  <pre><code>&lt;style name="Spinner" parent="@android:style/Widget.Holo.Spinner"&gt;
          &lt;item name="android:layout_width"&gt;fill_parent&lt;/item&gt;
          &lt;item name="android:layout_height"&gt;@dimen/button_height&lt;/item&gt;
          &lt;item name="android:textSize"&gt;@dimen/spinner_text&lt;/item&gt;
          &lt;item name="android:textColor"&gt;@color/button&lt;/item&gt;
          &lt;item name="android:gravity"&gt;center_vertical&lt;/item&gt;
          &lt;item name="android:padding"&gt;2dp&lt;/item&gt;
          &lt;item name="android:maxLines"&gt;1&lt;/item&gt;
     &lt;/style&gt;
  </code></pre>
