【中文标题】滑动手势不支持用手指在 android 的滑动抽屉中的列表视图上【英文标题】：Swipe gesture not supporting with finger over listview in sliding drawer in android 【发布时间】：2014-11-20 03:38:04 【问题描述】：现在我正在使用带有列表视图的滑动抽屉控件。 我的问题是，我无法用手指在列表视图上滑动，但菜单（Toggle）按钮工作正常。 有没有人遇到过这样的情况，如果有，请帮我解决这个问题。 请提出建议。
我希望下面的图片能让您清楚地了解我的问题

【参考方案1】：这不是来自官方 Android SDK 的滑动抽屉。这是一个定制的。正如文档中所述，您需要阅读资源以添加滑动。为此，我建议您阅读this 文章。
