如何在对话框中显示google map api v2，当我点击一个按钮

我陷入困境。我有一个自定义列表适配器的自定义列表。每个列表项都有一个按钮，如果我点击这个按钮，弹出的对话框应该包含谷歌地图（稍后用标记）。我尝试将片段分配给SupportMapFragment，但Android Studio告诉我，“getSupportFragmentManager（）无法解析方法”。我的问题是如何把这个地图（片段）的对话框？如何在对话框中显示google map api v2，当我点击一个按钮

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context="hu.bognaroliver.bajaintezemnyek.CustomListAdapter"> 

<TextView 
    android:id="@+id/header" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Hello World!" 
    android:layout_alignParentTop="true" /> 

<fragment 
    android:id="@+id/map" 
    android:layout_alignParentBottom="true" 
    android:layout_below="@+id/header" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:name="com.google.android.gms.maps.MapFragment"/> 

</RelativeLayout>

这是地图。

快捷方式通过itemClick在使用谷歌的MapView

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context="hu.bognaroliver.bajaintezemnyek.CustomListAdapter"> 

<TextView 
    android:id="@+id/header" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Hello World!" 
    android:layout_alignParentTop="true" /> 

<com.google.android.gms.maps.MapView 
    android:id="@+id/map_view" 
    android:layout_below="@+id/header" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"> 
</com.google.android.gms.maps.MapView> 
<Button 
    android:id="@+id/btn_ok" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="ok" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentRight="true"/> 
<Button 
    android:id="@+id/btn_cancel" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="ok" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentLeft="true"/> 

</RelativeLayout>

做到这一点显示对话框

new Dialog(getContext()) { 
     @Override 
     protected void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.your_layout); 
      MapView map = findViewById(R.id.map_view); 
      map.getMapAsync(new OnMapReadyCallback() { 
       @Override 
       public void onMapReady(GoogleMap googleMap) { 
        //add marker here 
        googleMap.addMarker(new MarkerOptions() 
          .position(lng) 
          .title("Marker Title")); 

        googleMap.setOnMarkerClickListener(
         new OnMarkerClickListener() { 
         @Override 
         public boolean onMarkerClick(Marker arg0) { 
          // Marker source is clicked 

          return true; 
         } 

        }); 
       } 
      }); 


      findViewById(R.id.btn_ok).setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        //do something 

       } 
      }); 
      findViewById(R.id.btn_cancel).setOnClickListener(new   View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 
        dismiss(); 

       } 
      }); 

     } 
    }.show();

试这一个

Dialog dialog = new Dialog(getActivity()); 
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
dialog.setContentView(R.layout.dialogmap); 
dialog.show(); 
GoogleMap googleMap; 


MapView mMapView = (MapView) dialog.findViewById(R.id.mapView); 
MapsInitializer.initialize(getActivity());   

mMapView = (MapView) dialog.findViewById(R.id.mapView); 
mMapView.onCreate(dialog.onSaveInstanceState()); 
mMapView.onResume();// needed to get the map to display immediately 
googleMap = mMapView.getMap();

它几乎可以工作，但是当我点击列表项中的按钮时，屏幕只会变灰，就像对话框想要加载的一样。但是在这种情况下，屏幕上没有任何东西只出现灰色的“图层”。 –

第二个人可能会帮助你 –

哦，很好。第二个是为我工作。谢谢：） –

mMap.addMarker(new MarkerOptions() 
       .position(lng) 
       .title("Marker Title")); 

       mMap.setOnMarkerClickListener(new OnMarkerClickListener() 
       { 

        @Override 
        public boolean onMarkerClick(Marker arg0) { 
         // Marker source is clicked 

         return true; 
        } 

       });
