我能够使用以下代码让它工作:

I was able to get it working with this code:

 @Override
 public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    Log.d(LOG_TAG, "onUpdate(): ");
    for (int appWidgetId : appWidgetIds) {

        Intent callIntent = new Intent(Intent.ACTION_CALL);
        callIntent.setData(Uri.parse("tel:"+number));
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, callIntent, 0);

        // Get the layout for the App Widget and attach an on-click listener to the button
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.caller);
        views.setOnClickPendingIntent(R.id.callButton, pendingIntent);

        // Tell the AppWidgetManager to perform an update on the current App Widget
        appWidgetManager.updateAppWidget(appWidgetId, views);
    }
}
