    Intent intent = new Intent();

            Constants.ACTION_WIDGET_UPDATE_FROM_ACTIVITY)) {
        String widgetText = intent.getExtras().getString(
                Constants.INTENT_EXTRA_WIDGET_TEXT);
        remoteViews.setTextViewText(R.id.word_text, widgetText);

在您的活动中尝试此代码....

   if (appWidgetId != AppWidgetManager.INVALID_APPWIDGET_ID) {
                AppWidgetManager appWidgetManager = AppWidgetManager
                        .getInstance(context);
                RemoteViews remoteViews = new RemoteViews(context
                        .getPackageName(), R.layout.widget_layout);


                remoteViews.setTextViewText(R.id.txt_time, ""
                        + YOURTIME);



                appWidgetManager.updateAppWidget(appWidgetId, remoteViews);
                Intent resultValue = new Intent();
                resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
                        appWidgetId);
                setResult(RESULT_OK, resultValue);
            }

如何从活动中向窗口小部件发送时间？
