如何修复android.view.InflateException：使用Google Maps v2片段时，错误放大类片段

Question

我正在使用google map v2片段作为tabhost的选项卡内容。 我第一次获得应该显示的地图，但是当我使用选项卡导航并且想返回到地图所在的选项卡时，出现此错误：

这是我的片段。JAVA：

public class MapFragment extends Fragment {

private GoogleMap map;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.activity_tab_map, container, false);

    map = ((SupportMapFragment) getFragmentManager()
            .findFragmentById(R.id.tabmap)).getMap();
    map.setMapType(GoogleMap.MAP_TYPE_NORMAL);

    return rootView;
}

这是我的布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

<fragment 
    android:id="@+id/tabmap"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentTop="true"
    android:layout_alignParentBottom="true"
    android:name="com.google.android.gms.maps.SupportMapFragment"/> 

<Button
android:id="@+id/btn_tabmapyaller"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="250dp"
android:text="Y aller" /> 

</RelativeLayout>

编辑（已解决） ：最后，我找到了解决方案。 方法onDestroyView（）应该按以下方式添加到JAVA文件MapFragment中：

@Override
public void onDestroyView() {
    super.onDestroyView();
    SupportMapFragment f = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.tabmap);
    if (f != null && f.isResumed()){
        getFragmentManager().beginTransaction().remove(f).commit();
    }
}

检查一下 ：

您的问题，可能是清单文件的应用程序标记中的元数据标记错误（或不存在）。 应该是这样的：

<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="@integer/your_google_maps_version" />

UPD_0：

您的stackTrace中有一行：

重复的ID 0x7f0a0083，标记为null或父ID 0x0（带有com.google.android.gms.maps.SupportMapFragment的另一个片段）

可能是，当您导航回已经创建（并存储在FragmentManager中）的MapFragment时，您创建了另一个，而不是显示旧的？
