如何在android的widget中编程设置secondaryProgress？

<ProgressBar
    android:id="@+id/progressBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:secondaryProgress="50"
    />

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
    for (int appWidgetId : appWidgetIds) {
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
        
        // 获取ProgressBar组件的实例
        ProgressBar progressBar = views.findViewById(R.id.progressBar);
        
        // 设置secondaryProgress的值
        progressBar.setSecondaryProgress(50);
        
        // 更新widget
        appWidgetManager.updateAppWidget(appWidgetId, views);
    }
}
