带有地图的Android选项卡

我想用三个选项卡创建一个具有三个选项卡的Android应用程序（我已使用本教程：http://wptrafficanalyzer.in/blog/creating-navigation-tabs-using-tabhost-and-fragments-in-android/，因为它应该适用于大量设备），其中两个应显示地图。带有地图的Android选项卡

我抬头寻找这个案例的教程，但我没有找到合适的东西。那我该怎么做？有人可以帮我或给一个链接，解释这样的事情？我希望这个问题很容易回答你，我很感激每一个答案。

更新：我现在尝试一些东西，但我尝试的方式不起作用：全码：

过去，这是一个有点棘手做，直到MapFragment出来。您将需要用MapFragment替换您的通用片段。您还需要一个API密钥等，就像您使用MapActivity创建地图一样。有关更多信息，请查看Android Google地图开发人员指南。

从UX的角度来看，选项卡中的地图可能不是最好的主意。如果您使用选项卡创建滑动视图，则您将有两个可滚动的视图。如果你不这样做，你只能在屏幕顶部切换按钮。

我会使用按钮，你有点击无论如何，我已经想出了如何使用它的API密钥等地图... 但我究竟如何利用mapfragment在标签中呢？ – Kon

为什么MapsFragment.java中有一个MapsActivity？您的映射宿主应该扩展一个MapFragment而不是一个FragmentActivity。 MapFragment是Fragment的子类，FragmentActivity是Activity的子类。 – LukaCiko

我改变MapsActivity到MapsFragment但仍一些错误其大概easyly固定： XML：片段：机器人：layout_below = “@ ID/tv_location” MapsFragment.java：公共无效：TextView的tvLocation =（TextView的）findViewById（R .id.tv_location）; MainActivity：public void：MapsFragment mapsFragment =（MapsFragment）fm。findFragmentByTag（ “映射”）; /**如果存在，则分离mapsfragment */ if（mapsFragment！= null） ft.detach（mapsFragment）; （R.id.realtabcontent，new MapsFragment（），“maps”）; ft.attach（mapsFragment）; – Kon
