以编程方式更改小部件布局

问题描述

假设我有两个小部件布局:Layout1 和 Layout2.小部件的默认值为 Layout1，但我允许用户选择他们希望小部件成为哪种布局.因此，如果用户更改为Layout2，如何以编程方式将布局更改为 Layout2?

Let's say that I have two layouts for a widget: Layout1 and Layout2. The default for the widget is Layout1, but I allow the user to choose which layout they want the widget to be. So if the user changes to Layout2, how do I programmatically change the layout to Layout2?

小部件没有像活动那样的 setContentView 方法.

There isn't a setContentView method for widgets like there is for Activities.

谢谢

推荐答案

在构建 remoteView 时必须选择布局.在我的小部件代码中:

You have to choose the layout when you're building your remoteView. In my widget code:

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);

}
