Question

我跟着this tutorial将地图添加到我的某个标签中。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（除非我双击）。向左/向右滑动有效，但地图移动很少。我制作了一个customViewPager，它禁用了滑动选项卡，但没有为他映射做任何事情。

起初我使用了tabActivity，我的地图片段按原样运行，看起来像这样：

   mapActivity extends FragmentActivity...

由于tabActivity已弃用，我按照上面的教程添加了滑动标签。无法使用FragmentActivity添加地图，只能使用Fragment，因此我将地图片段更改为：

   mapActivity extends Fragment...

现在我遇到以下问题 - 我无法浏览地图。未检测到滑动和触摸输入。我无法上下移动，放大或缩小，我唯一能做的就是从左向右移动，但速度非常慢。

试试这个。它的样本。 100％工作

Answer 2

首先我在app_bar_main中添加了tabLayout和viewPager到appBarLayout（我用导航抽屉创建了一个应用程序），后来我将appBarLayout移动到了content_main并且它运行了。

Map没有检测到android中的触摸/滑动
