Question

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一个对话框，弹出应该包含谷歌地图（后面带标记）。我试图将片段分配给SupportMapFragment，但Android Studio告诉我，“getSupportFragmentManager（）无法解析方法”。我的问题是如何将这个地图（片段）放入对话框？

<?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。

Answer 1

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;
                    }

                });

使用Google MapView

执行此操作的快捷方式

 <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>

在itemclick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();

尝试这个

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();

当我点击一个按钮时，如何在对话框中显示谷歌地图api v2
