Change Icon on onReceive method - widget Android

Question

I developed a widget for Android with the intention of clicking a text widget's icon is changed. To do this I set the action and I have tried the method OnReceive action. This is the code:

@Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(ACTION_WIDGET_NOTIF)) {
            Bundle extras = intent.getExtras();
            int appWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID);
            RemoteViews controles = new RemoteViews(context.getPackageName(),
                    R.layout.widgetcuatroxuno);
            controles.setImageViewResource(R.id.btt,
                    R.drawable.ic_launcher_new);
            AppWidgetManager.getInstance(context).updateAppWidget(appWidgetId, controles);
        } else {
            super.onReceive(context, intent);
        }

    }

I know I need AppWidgetManager to update the widget controls, but it failed. How I can fulfill my purpose? Sorry for my English. Thank you very much for everything.

RemoteViews control = new RemoteViews(context.getPackageName(),
                    R.layout.widget);
            control.setTextViewText(R.id.textview1, "ExampleText");

            ComponentName cn = new ComponentName(context,
                    ButtonWidget.class);
            AppWidgetManager.getInstance(context).updateAppWidget(cn,
                    control);

This one works in OnReceive(), thanks a lot!
