java - Android SDK v9 上的 Google map V2 'the application has stopped unexpectedly'

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，然后转移到 Android。

我已关注this教程在手机上运行时出现标题中提到的错误。我听说 10 以下的 SDK 不支持 map ，是吗？非常不确定从这里该做什么。代码:

我有 3 个选项卡，我将它们作为 fragment 加载，有问题的 fragment 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;
    }
}

在查看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"
    />

一切都在 list 中。当我删除它时，它运行良好。有解决这种问题的方法吗？

Answer 1

我认为您需要实现 SupportFragment 并且 fragment 类需要为:class="com.google.android.gms.maps.SupportMapFragment"
