java - 与 com.google.android.gms.maps.SupportMapFragment 的另一个 fragment 重复 ID、标记 null 或父 ID 0x0

Question

基本上，当我在一段时间不活动后打开一个 fragment 时，应用程序会崩溃，或者将其留在后台，或者在应用程序打开的情况下解锁手机。

我看了这个答案，但老实说我无法解决，如果有人能具体指正我的代码并解释一下，我将不胜感激

我有多个 mapfragment，放一个，但问题出在我拥有的 21 个中的任何一个

fragment .java:

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.actionbarsherlock.app.SherlockFragment;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

public class Fragment0 extends SherlockFragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment0, container, false);
return rootView;
}

@Override
public void onViewCreated(View v, Bundle savedInstanceState){
super.onViewCreated(v, savedInstanceState);

final LatLng Initial = new LatLng(-34.673009, -58.474111);
final LatLng FADU = new LatLng(-34.542163, -58.443716);



GoogleMap googlemap;

googlemap  = ((SupportMapFragment)   getFragmentManager().findFragmentById(R.id.map0)).getMap();

googlemap.setMyLocationEnabled(true);
googlemap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(Initial, 10);
googlemap.animateCamera(update);


googlemap.addMarker(new MarkerOptions().position(FADU).title("FADU").snippet("Facultad de Arquitectura, Diseño y Urbanismo")
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_BLUE)));

}

@Override
public void onPause() {
super.onPause();

}
@Override
public void onDestroyView() {

super.onDestroyView(); 
Fragment fragment = (getFragmentManager().findFragmentById(R.id.map0));  
if (fragment != null){
getActivity().getSupportFragmentManager().beginTransaction()
.remove(fragment)
.commit();          
}
}

fragment .xml:

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

<fragment
android:id="@+id/map4"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>

</RelativeLayout>

使用以下代码。它对我有用

private static View view;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (view != null) {
    ViewGroup parent = (ViewGroup) view.getParent();
    if (parent != null)
        parent.removeView(view);
}
try {
    view = inflater.inflate(R.layout.map, container, false);
} catch (InflateException e) {
    /* map is already there, just return view as it is */
}
return view;
}
