以编程方式更改小部件布局

Question

假设我有一个小部件的两个布局:Layout1和Layout2.窗口小部件的默认设置是Layout1,但我允许用户选择他们想要窗口小部件的布局.因此,如果用户更改为Layout2,如何以编程方式将布局更改为Layout2？

对于小部件,没有像活动那样的setContentView方法.

谢谢

在构建remoteView时必须选择布局.在我的小部件代码中:

public static RemoteViews buildUpdate(Context context, String action) {
    RemoteViews updateViews;            
    SharedPreferences prefs = context.getSharedPreferences(PREFS_NAME, 0);
    String typeface = prefs.getString("typeface", "sans");
    int layoutId = R.layout.widget_sans;
    if ("monospace".equals(typeface)){
        layoutId = R.layout.widget_mono;
    } else if ("serif".equals(typeface)){
        layoutId = R.layout.widget_serif;
    }
    updateViews = new RemoteViews(context.getPackageName(),
        layoutId);
    //actually do things here
    //then finally, return our remoteView
    AppWidgetManager.getInstance(context).updateAppWidget(
        new ComponentName(context, FuzzyWidget.class), updateViews);

}
