Android片段Google Maps V2:膨胀类片段时出错
我正在开发一个使用fragment tab的应用程序,我的一个fragment使用Google Maps V2Android片段Google Maps V2:膨胀类片段时出错,android,google-maps,android-fragments,Android,Google Maps,Android Fragments,我正在开发一个使用fragment tab的应用程序,我的一个fragment使用Google Maps V2 public class AppMapFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.infl

我的xml:

android:orientation="vertical"
android:background="#17df0d">
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
我只复制了部分错误,因为它相当长:(.每当我尝试运行应用程序时,就会发生此错误。它引用的行是
View rootView=inflater.inflate(R.layout.fragment\u map,container,false)
。任何帮助都将不胜感激!请提前感谢查看此实现,您应该像以前一样,创建一个带有映射的片段:
public class MapFragment extends Fragment
创建布局:
mapview.xml:
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="@+id/mapview"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
map:cameraZoom="12"
map:mapType="normal"
map:uiZoomControls="false"
map:uiRotateGestures="true"
map:uiScrollGestures="true"
map:uiZoomGestures="true"
map:uiTiltGestures="false" />
然后,要获取映射实例,请执行以下操作:
private GoogleMap getGoogleMap() {
if (map == null && getActivity() != null && getActivity().getSupportFragmentManager()!= null) {
SupportMapFragment smf = (SupportMapFragment)getActivity().getSupportFragmentManager().findFragmentById(R.id.mapview);
if (smf != null) {
map = smf.getMap();
}
}
return map;
}
我只是想知道为什么你想在另一个片段中膨胀一个MapFragmet(它已经是一个片段了)。我的应用程序包括五个选项卡,其中一个是地图。我认为这样做的方法是:(
<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="@+id/mapview"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
map:cameraZoom="12"
map:mapType="normal"
map:uiZoomControls="false"
map:uiRotateGestures="true"
map:uiScrollGestures="true"
map:uiZoomGestures="true"
map:uiTiltGestures="false" />
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.mapview, container, false);
}
private GoogleMap getGoogleMap() {
if (map == null && getActivity() != null && getActivity().getSupportFragmentManager()!= null) {
SupportMapFragment smf = (SupportMapFragment)getActivity().getSupportFragmentManager().findFragmentById(R.id.mapview);
if (smf != null) {
map = smf.getMap();
}
}
return map;
}
