扩展类片段时出错:使用另一个片段复制id,标记null或parent id

Question

我正在尝试制作一个应用,当用户点击ListView中的项目时,会显示GoogleMaps.

我试过以下代码:

ShowPlacesActivity.java

public class ShowPlaceActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_show_place);
        if (savedInstanceState == null) {
            getFragmentManager().beginTransaction()
                    .add(R.id.container_showplaces, new PlaceholderFragment())
                    .commit();
        }
        getActionBar().setSubtitle(getString(R.string.activity_showplaces_subtitle));
    }

}

activity_show_place.xml

<FrameLayout

    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:id="@+id/container_showplaces"
    android:layout_width="match_parent" android:layout_height="match_parent"
    tools:context="com.krupal.rememberthisplace.ShowPlaceActivity" tools:ignore="MergeRootFrame" />

fragment_show_place.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent"
    android:orientation="vertical"

    >


    <ListView
        android:id="@+id/listView_places"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
      />


</LinearLayout>

fragment_maps.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

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

</RelativeLayout>

我想在listview的项目上显示地图点击...所以,我已经实现了两个片段,如下所示:

在PlaceholderFragment.java中,我设置onitemclicklistener为:

@Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_show_place, container, false);



            final MySqliteHelper db = new MySqliteHelper(getActivity().getBaseContext());


            listview_places = (ListView)rootView.findViewById(R.id.listView_places);

            final PlacesAdapter places_adapter = new PlacesAdapter(getActivity(),R.layout.listview_item_row,places);


            listview_places.setAdapter(places_adapter);


            listview_places.setLongClickable(true);

            listview_places.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                                        int position,long id) {
                    Place place = places_adapter.getItem(position);
                    String dbvaluename = place.getname();

                  Place selectedplace =  db.getPlace(dbvaluename);


                    dblatitude = selectedplace.getlatitude();

                    dblongitude = selectedplace.getlongitude();


                    dbplacename = place.getname();

                   maps = new MapsFragment();
                    Bundle bundle = new Bundle();
                    bundle.putDouble("dbplacename",dblatitude);
                    bundle.putDouble("dbplacename",dblongitude);
                    bundle.putString("dbplacename",dbplacename);
                   maps.setArguments(bundle);
                    FragmentManager fm = getFragmentManager();

                    FragmentTransaction ft = fm.beginTransaction();

                    ft.replace(R.id.container_showplaces,maps);

                    ft.addToBackStack(null);

                    ft.commit();

                }



        });
}
}

在MapsFragment.java中,我将地图显示为:

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


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


    try {
        // Loading map
        initilizeMap();

    } catch (Exception e) {
        e.printStackTrace();
    }
    return rootView;
}

当我第一次点击ListView的项目时,它会显示Map ...然后,当我选择另一个项目时,它会崩溃:

Logcat日志:

我现在解决了!

另一个解决方案是链接的答案对我有用.

正如那里所解释的,我添加onDestroyView()了包含地图的片段.

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