Pourquoi mon TableLayout n'est pas autorisé à être gonflé?

Question

Pour un widget J'utilise une mise en page simple qui contient un TableLayout

<?xml version="1.0" encoding="utf-8"?> 
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" 
    android:layout_height="wrap_content"> 
    <TableRow > 
     (...) 
    </TableRow> 
</TableLayout> 

Mais quand je veux mettre à jour son contenu en créant un RemoteViews

RemoteViews eventElementLayout = new RemoteViews(this.getPackageName(), R.layout.widget_events_element); 

Je suis une exception en me disant que TableLayout est pas autorisé à être gonflé.

Pourquoi?

Merci à l'avance

widgets App permettent uniquement la liste limitée des types de widgets et mise en page de vue qui peuvent être utilisés en leur sein. Il semble que TableLayout n'est pas supporté. Des développeurs Google documentation:

Un objet RemoteViews (et, par conséquent, un Widget App) peut soutenir les classes de mise en page suivantes:

* FrameLayout 
* LinearLayout 
* RelativeLayout 

et les classes de widget ci-dessous:

* AnalogClock 
* Button 
* Chronometer 
* ImageButton 
* ImageView 
* ProgressBar 
* TextView 

Les descendants de ces classes ne sont pas supportés.
