android – 重复的id与片段

我正在尝试应用drawernavigation(我的第一个片段是一个地图,而其他的只是一些简单布局的片段).它运行正常&我可以在我的碎片之间导航,但是当我回到第一个片段,这是一张地图,我遇到了一个崩溃

logcat的：

我认为这是最重要的：

Duplicate id 0x7f05000c,or parent id 0xffffffff with another fragment for com.google.android.gms.maps.MapFragment

所以这是我的代码：
LoginScreen：一个fragmentActivity,它使所有调用片段

这是我对fragmentActivity的主要布局：

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Framelayout to display Fragments -->
    <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

   </FrameLayout>

    <!--     

<fragment
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.MapFragment"/>

     -->

    <!-- Listview to display slider menu -->
    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"        
        android:listSelector="@drawable/list_selector"
        android:background="@color/list_background"/>

</android.support.v4.widget.DrawerLayout>

这是mapfragment的xml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/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.MapFragment"/>

</RelativeLayout>

这是mapfragment代码：

public class HomeFragment extends Fragment {


      int mCurrentPosition = -1;
MapFragment mMap;
    GoogleMap googleMap;
    final static String ARG_POSITION = "position";

    public HomeFragment(){}

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

          if (savedInstanceState != null) {
                mCurrentPosition = savedInstanceState.getInt(ARG_POSITION);
            }
        View rootView = inflater.inflate(R.layout.fragment_map,container,false);
//        int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
//        if(status == ConnectionResult.SUCCESS) {
//                    // what you want to do
//          //Toast.makeText(getApplicationContext(),Toast.LENGTH_SHORT).show();
//        }

        setUpMapIfNeeded();
        addTwitterMarq();
        return rootView;
    }




    private void addTwitterMarq() {
        // TODO Auto-generated method stub


    LatLng pos = new LatLng(48.85078,-73.595))
        .radius(100);

        Circle circle = googleMap.addCircle(circleOptions);

    }
@Override
    public void onResume() {
        // TODO Auto-generated method stub
        super.onResume();
        //setUpMapIfNeeded();
        //addTwitterMarq();
    }

@Override
public void onSaveInstanceState(Bundle outState) {
    // TODO Auto-generated method stub
    super.onSaveInstanceState(outState);
    outState.putInt(ARG_POSITION,mCurrentPosition);

}
public void updateArticleView(int position) {
    mCurrentPosition = position;
}
@Override
public void onStart() {
    // TODO Auto-generated method stub
    super.onStart();
     Bundle args = getArguments();
     if (args != null) {
         // Set article based on argument passed in
         updateArticleView(args.getInt(ARG_POSITION));
     } else if (mCurrentPosition != -1) {
         // Set article based on saved instance state defined during onCreateView
         updateArticleView(mCurrentPosition);
     }
}
}

我认为这个问题位于onResume& onCreateView方法!!
希望你能帮助我
谢谢.

解决方法

用这个

<fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.SupportMapFragment"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
         />

并重写方法OnDestroyView并将此代码放在OnDestroyView()

public void onDestroyView() 
 {
    super.onDestroyView(); 
    Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));  
    FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
    ft.remove(fragment);
    ft.commit();
}
