title: Nativescript : is it simple to make listview scrollbar always visible?
body: <p>I am using this template on the main page of my application :</p>
  
  <pre><code>&lt;ActionBar title="{{ 'activity_explorer' | L }}" row="0" android.icon="res://icon"
  android.iconVisibilty="always"&gt;
      &lt;ActionItem icon="res://icon_plus" text="{{'menuitem_new' | L}}" (tap)="showMenuItemNew()"&gt;&lt;/ActionItem&gt;
  &lt;/ActionBar&gt;
  
  &lt;GridLayout rows="*" modal-dialog-host&gt;
  
      &lt;ListView row="0" [items]="_filesObservable | async"&gt;
          &lt;template let-item="item"&gt;
              &lt;GridLayout columns="1*, 7*" (tap)="processItem(item)"&gt;
                      &lt;Image col="0" [src]="item.isDirectory()? 'res://folder' : 'res://file'"&gt;&lt;/Image&gt;
                      &lt;Label col="1" [text]="item.name()" textWrap="true"&gt;&lt;/Label&gt;
              &lt;/GridLayout&gt;
          &lt;/template&gt;
      &lt;/ListView&gt;
  
  &lt;/GridLayout&gt;
  </code></pre>
  
  <p>(I am also using an external css file for the related component)</p>
  
  <p>I am using Angular2 and TypeScript version.</p>
  
  <p>Is there a simple way to make the listview scrollbar always visible ?</p>
  
  <p>Edit : is there also a portable solution, that can work on Android as well as on IOS ?</p>
