Showing list of text App widget - Android

I try to list some text in an app widget. When I run my widget I have no error but I my widget is empty. I mean I have juste the launcher icon

Can you please help me to know why ?

This is my code :

WidgetService:

import android.content.Intent;
import android.widget.RemoteViewsService;


public class WidgetService extends RemoteViewsService
{
    @Override
    public RemoteViewsService.RemoteViewsFactory onGetViewFactory(Intent intent)
    {
        return(new WidgetDisplay(this.getApplicationContext(),
                intent));
    }
}

Widget Provider :

import android.app.PendingIntent;
import android.appwidget.AppWidgetManager;
import android.appwidget.AppWidgetProvider;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.widget.RemoteViews;

public class WidgetProvider extends AppWidgetProvider
{
    public static String EXTRA_WORD=
            "com.commonsware.android.appwidget.lorem.WORD";

    @Override
    public void onUpdate(Context ctxt, AppWidgetManager appWidgetManager,
                         int[] appWidgetIds)
    {
        for (int i=0; i<appWidgetIds.length; i++)
        {
            Intent svcIntent=new Intent(ctxt, WidgetService.class);

            svcIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
            svcIntent.setData(Uri.parse(svcIntent.toUri(Intent.URI_INTENT_SCHEME)));

            RemoteViews widget=new RemoteViews(ctxt.getPackageName(),
                    R.layout.widget);

            widget.setRemoteAdapter(appWidgetIds[i], R.id.words,
                    svcIntent);

            appWidgetManager.updateAppWidget(appWidgetIds[i], widget);
        }

        super.onUpdate(ctxt, appWidgetManager, appWidgetIds);
    }
}

WidgetDisplay :

import android.appwidget.AppWidgetManager;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.widget.RemoteViews;
import android.widget.RemoteViewsService;


public class WidgetDisplay implements RemoteViewsService.RemoteViewsFactory
{
    private static final String[] items={"Red", "Green", "Blue", "Pink", "Orange"};
    private Context ctxt=null;
    private int appWidgetId;

    public WidgetDisplay(Context ctxt, Intent intent)
    {
        this.ctxt=ctxt;
        appWidgetId=intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
                AppWidgetManager.INVALID_APPWIDGET_ID);
    }

    @Override
    public void onCreate()
    {
        // no-op
    }

    @Override
    public void onDestroy()
    {
        // no-op
    }

    @Override
    public int getCount()
    {
        return(items.length);
    }

    @Override
    public RemoteViews getViewAt(int position)
    {
        RemoteViews row=new RemoteViews(ctxt.getPackageName(),
                R.layout.row);

        row.setTextViewText(android.R.id.text1, items[position]);

        Intent i=new Intent();
        Bundle extras=new Bundle();

        extras.putString(WidgetProvider.EXTRA_WORD, items[position]);
        i.putExtras(extras);
        row.setOnClickFillInIntent(android.R.id.text1, i);

        return(row);
    }

    @Override
    public RemoteViews getLoadingView()
    {
        return(null);
    }

    @Override
    public int getViewTypeCount()
    {
        return(1);
    }

    @Override
    public long getItemId(int position)
    {
        return(position);
    }

    @Override
    public boolean hasStableIds()
    {
        return(true);
    }

    @Override
    public void onDataSetChanged()
    {
        // no-op
    }
}
