title: Android options Menu horizontal divider
body: <p>I'm having a problem while showing the options menu in a Samsung Galaxy phone, with Android 2.2.
  My menu has four items, and I arranged them in what I think is the default way:</p>
  
  <p>
  </p>
  
  <pre><code>    &lt;item android:id="@+id/feedback" 
            android:icon="@drawable/ic_menu_send"
            android:title="@string/feedback" /&gt;
  
      &lt;item android:id="@+id/share" 
            android:icon="@drawable/ic_menu_share"
            android:title="@string/share" /&gt;
  
      &lt;item android:id="@+id/sign_out" 
            android:icon="@drawable/ic_menu_close_clear_cancel"
            android:title="@string/sign_out" /&gt;
  
      &lt;item android:id="@+id/preferences" 
            android:icon="@drawable/ic_menu_preferences"
            android:title="@string/preferences" /&gt;
  </code></pre>
  
  <p></p>
  
  <p>On the corresponding activity, I'm inflating the menu this way:</p>
  
  <pre><code>@Override
  public boolean onCreateOptionsMenu(Menu menu) {
      MenuInflater inflater = getMenuInflater();
      inflater.inflate(R.menu.sr_menu, menu);
      return true;
  }
  </code></pre>
  
  <p>When the menu shows, I can't see the horizontal line that separates the two upper items from the lower ones. The grid appears as two adyacent columns, instead of four squares.
  In the emulator it seems to be working fine, but in the phone I'm having that issue.</p>
  
  <p>Any ideas? Should I create a custom menu instead? I don't want to change any other attribute of the menu, just expect the default behavior.</p>
  
  <p>Thanks in advance.</p>
