我有一个带有一些碎片的导航抽屉.每个片段在布局中都有一个MapFragment.最初,当应用程序运行导航抽屉时,单击打开片段一次,但是当我单击相同的导航项以第二次打开相同的片段时(在访问其他片段后),我在onCreateView()中收到以下错误
Binary XML file line #1: Error inflating class fragment
下面是我的片段代码：
user_map_Fragment.xml
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="vertical"
android:id="@+id/parentContainer"
app:layout_behavior="@string/appbar_scrolling_view_behavior">
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="200dp"
android:name="com.google.android.gms.maps.MapFragment"/>
......
</LinearLayout>
MainFragment.cs
public class MainFragement : Android.Support.V4.App.Fragment,IOnMapReadyCallback,ILocationListener,Android.Views.View.IOnKeyListener
{
private GoogleMap mMap;
private LocationManager _locationManager;
private string _locationProvider;
private Android.Locations.Location _currentLocation;
public override View OnCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState)
{
if (v == null)
{
v = inflater.Inflate(Resource.Layout.Main,container,false);
SetUpMap();
InitializeLocationManager();
}
return v;
}
}
private void SetUpMap()
{
if (mMap == null)
{
Activity.FragmentManager.FindFragmentById<MapFragment>(Resource.Id.map).GetMapAsync(this);
}
}

我该如何解决这个问题？
解决方法
而不是这个
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="200dp"
android:name="com.google.android.gms.maps.MapFragment"/>
用这个
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="200dp"
/>
在java类中
