Question

如何在android中获取主屏幕的小部件和快捷方式列表。这是我的代码：

List<AppWidgetProviderInfo> infos = mAppWidgetManager.getInstalledProviders();

        for (int i = 0; i < infos.size(); i++) {
            int ids[] = mAppWidgetManager.getAppWidgetIds(infos.get(i).provider);
            if (ids.length != 0) {
                Log.d("TAG", "Found non-zero-length provider!");
                id = ids[0];
                info = infos.get(i);
                break;
            }
        }
