我在相同的活动中使用导航抽屉和网格视图但是一旦我这样做，我就无法滚动或点击活动上的任何内容。此外，导航抽屉还拒绝打开或响应触摸。我已经检查了我的代码至少3次，但我仍然无法弄清楚为什么它不起作用。

我检查了此页面中的步骤：creating a navigation drawer问题是，如果我删除抽屉或网格视图，一切正常。我尝试使缓存无效并重新启动（使用IntelliJ），但仍然没有运气。检查了有关SO的其他问题，但直到现在还没有解决这个问题。
答案 0 :(得分：0)
我不得不在gridview适配器类本身内移动gridview的onclick监听器然后开始工作了......不知道为什么会发生这种情况。
