Question

我正在使用老板的手机来测试我们在iOS上开发的应用程序并转移到Android。

我已经按照this教程，在手机上运行时会出现标题中提到的错误。我已经读过10以下的SDK不支持地图是吗？很不确定从这里做什么。代码：

我有3个标签，我作为片段加载，有问题的片段是：

注意：所有导入都是正确的

public class EventFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

      // Inflate the layout for this fragment
      View V = inflater.inflate(R.layout.event_layout, container, false);

        return V;
    }
}

在视图xml文件中：

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/the_map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.google.android.gms.maps.MapFragment"
    map:cameraTilt="45"
    map:cameraZoom="14"
    />

一切都应该在清单中。当我删除它运行正常。这种事情有解决方法吗？

Answer 1

我认为你需要实现SupportFragment，片段类需要是：class =“com.google.android.gms.maps.SupportMapFragment”

Answer 2

地图工作（afair）从API8开始。但是您需要将您的应用与google-play-servces_lib相关联，这很可能不是您的情况。还要确保您在Manifest中设置了所有权限。最后，查看官方文档：https://developers.google.com/maps/documentation/android/
