Google Map Lite in CardView

Question

Ich habe versucht, eine sehr einfache App mit Material Design zu spielen. Ich versuche, eine Listview (mit der neuen RecyclerView) in jedem Element ist eine Karte mit einem Google Maps Lite darin zu erstellen.

habe ich nach diesem Beispiel basicly worden: Creating Lists and Cards, für die Google Maps Implementierung i this example

Jedes Ding „Works“ verwendet haben, wenn ich in den Adapter nur ein Element haben (so gibt es nur einen Punkt zu Anzeige) , aber wenn ich ein zweites Element mit dem Adapter hinzufügen (so sollte es zwei Elemente in der Liste sein) die App stürzt ab, mit Ausnahme:

kann jemand mir sagen, was ich falsch mache?

neben dem Fehler kann ich nicht herausfinden, was wäre der beste Weg, Eigenschaften auf den einzelnen Karten (Center und so) zu setzen. Hilfe in diesem Bereich wäre auch sehr geschätzt.

Implementation als Referenz:

Aktivität

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

     mRecyclerView = (RecyclerView) rootView.findViewById(R.id.main_recycler_view); 

     mLayoutManager = new LinearLayoutManager(context); 
     mRecyclerView.setLayoutManager(mLayoutManager); 

     ArrayList<String> data = new ArrayList<>(); 
     data.add("Toeter"); 

     mAdapter = new MyAdapter(data, getChildFragmentManager()); 
     mRecyclerView.setAdapter(mAdapter); 

     return rootView; 
    } 

MyAdapter

@Override 
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    final View v = LayoutInflater.from(parent.getContext()) 
      .inflate(R.layout.card, parent, false); 

    ViewHolder vh = new ViewHolder(v); 
    return vh; 
} 

ViewHolder

public static class ViewHolder extends RecyclerView.ViewHolder { 
    public ViewHolder(View v) { 
     super(v); 
    } 
} 

Answer 1

Versuchen MapView statt MapFragment mit:

item.xml:

<android.support.v7.widget.CardView 
     android:id="@+id/card_view" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     app:cardCornerRadius="4dp"> 

     <com.google.android.gms.maps.MapView 
       android:id="@+id/map_view" 
       android:layout_width="match_parent" 
       android:layout_height="148dp" 

       app:liteMode="true" 
       app:mapType="normal" /> 

</android.support.v7.widget.CardView> 

RecyclerAdapter.java:

public ViewHolder(View itemView) { 
    super(itemView); 

    mapView = (MapView) itemView.findViewById(R.id.map_view); 
} 


@Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 

       holder.mapView.onCreate(null); 
       holder.mapView.getMapAsync(this); 

} 

Denken Sie daran, OnMapReadyCallback in RecyclerView.Adapter zu implementieren.

Answer 2

Try die Fragmente zur Laufzeit das Hinzufügen von neuen MapFragment() verwendet und so weiter. Ich habe oft mit diesem Fehler Probleme bekommen, wenn ich das Kartenfragment mehr als einmal vom selben Layout aufgepumpt habe. Sonderausgabe ...
