地图未检测到 android 中的触摸/滑动

Question

我关注this tutorial 将地图添加到我的一个标签中。它可以工作，但是当我打开地图选项卡时，我无法向上/向下滑动、放大/缩小（双击时除外）。向左/向右滑动有效，但地图移动很少。我做了一个customViewPager，它禁止滑动标签，但对他的地图没有任何作用。

起初我使用 tabActivity 并且我的地图片段正常工作，看起来像这样：

   mapActivity extends FragmentActivity...

由于不推荐使用 tabActivity，我按照上面的教程添加了滑动选项卡。地图不能用 FragmentActivity 添加，只能用 Fragment 所以我把地图片段改成：

   mapActivity extends Fragment...

现在我遇到以下问题 - 我无法导航地图。未检测到滑动和触摸输入。我不能向上或向下移动，不能放大或缩小，我唯一能做的就是从左向右移动，但它很慢。

试试这个。它的样本。 100% 正常工作

Answer 2

一开始我在app_bar_main的appBarLayout中添加了tabLayout和viewPager（我做了一个带有导航抽屉的应用程序），后来我把appBarLayout移到了content_main中，并且它工作了。
