how can get the information for place on google map?

问题

I want to use information from Google when I search restaurant or some place

i tried to make start an activity when the marker in Google Maps is clicked

so use the onMarkerClick but it have only name, address, place ID what i need

@Override
public boolean onMarkerClick(Marker marker) {
    Id = marker.getId();

    String Title = marker.getTitle();
    String Address = marker.getSnippet();

    switch(databaseCheck){
        case 1:
            Intent intent = new Intent(mActivity, PopupGrid.class);
            intent.putExtra("Title" , Title);
            intent.putExtra("Address", Address);
            getActivity().startActivity(intent);
            break;
        case 2:
            Intent intent2 = new Intent(mActivity, Nodatabase.class);
            intent2.putExtra("Title" , Title);
            intent2.putExtra("Address", Address);
            getActivity().startActivity(intent2);
            break;
    }

    return true;
}

how get other information like phone number, rating and Photo of that location?

You want to show more data in marker info window so you need to put some data in marker when it create .you should make some new things like that: 1. Firstly create a hash map to put the value.

 HashMap<String, String> map = new HashMap<>();
        map.put("userId", userId);
        map.put("userName", name);
        if(profileImage.equalsIgnoreCase(""))
        map.put("imageUrl", null);
        else
            map.put("imageUrl", profileImage);
        map.put("primaryInstrumentName", primary_Instrument_name);

        googleMap.addMarker(new MarkerOptions()
                .position(new LatLng(Double.valueOf(latitude), Double.valueOf(lonnitude))).snippet(String.valueOf(map))
                .icon(R.drawable.marker);

when u set listner on google map info window its return the marker object get marker.getsnippet which return the hashmap type string convert it in single key value according to this code:

 private Map<String, String> getMarkerDetails(Marker marker) {
        String name2 = marker.getSnippet();
        System.out.println("name  "+name2);

        name2 = name2.substring(1, name2.length() - 1);
        String[] keyValuePairs = name2.split(",");
        Map<String, String> map = new HashMap<>();

        for (String pair : keyValuePairs) {
            String[] entry = pair.split("=");
            System.out.println("name map is "+entry[0]+" "+entry[1]);
            map.put(entry[0].trim(), entry[1].trim());
        }
        return map;
    }

this would help to get back key value from string hashmap using this like:

getMarkerDetails(marker).get("userName").toString();

this will return to marker "username" data , use wherever need.

Try this full example of custom marker.

Map Activity :

public void onMapReady(GoogleMap googleMap) { 
mMap.clear();
LinearLayout tv2;
tv2 = (LinearLayout)MapsActivity.this.getLayoutInflater().inflate(R.layout.marker_dialog, 
null, false);
tv2.measure(View.MeasureSpec.makeMeasureSpec(0, 
View.MeasureSpec.UNSPECIFIED), View.MeasureSpec.makeMeasureSpec(0, 
View.MeasureSpec.UNSPECIFIED));
tv2.layout(0, 0, tv2.getMeasuredWidth(), tv2.getMeasuredHeight());
tv2.setDrawingCacheEnabled(true);
tv2.buildDrawingCache();
Bitmap bm2 = tv2.getDrawingCache();
icon2 = BitmapDescriptorFactory.fromBitmap(bm2);
BitmapDescriptorFactory.fromResource(R.drawable.ic_markericon);

HashMap<Marker, JSONObject> stopsMarkersInfo = new HashMap<>();
JSONObject ObjectForMarker;
for (int i = 0; i < YourData.length(); i++) 
{//YourData is JSONArray
  LatLng coordinate = new LatLng(Latitude, Longitude);
  ObjectForMarker = YourData.getJSONObject(i);
  MarkerOptions markerOptions = new 
  MarkerOptions().position(coordinate).icon(Youricon);
  Marker marker = mMap.addMarker(markerOptions);
  stopsMarkersInfo.put(marker, ObjectForMarker); 
}
 googleMap.setInfoWindowAdapter(new StopsInfoWindow(stopsMarkersInfo, getApplicationContext()));
     }

Custom Adapter Class :

  import android.content.Context;
  import android.view.LayoutInflater;
  import android.view.View;
  import android.widget.TextView;
  import com.google.android.gms.maps.GoogleMap;
  import com.google.android.gms.maps.model.Marker;
  import org.json.JSONException;
  import org.json.JSONObject;
  import java.util.HashMap;
  public class StopsInfoWindow implements GoogleMap.InfoWindowAdapter {

private HashMap<Marker, JSONObject> stopsMarkersInfo;
private View view;
Context context;

public StopsInfoWindow(HashMap<Marker, JSONObject> stopsMarkersInfo, Context context) {
    this.stopsMarkersInfo = stopsMarkersInfo;
    this.context = context;
}


@Override
public View getInfoContents(Marker marker) {
    return null;
}

@Override
public View getInfoWindow(final Marker marker) {
    JSONObject stop = stopsMarkersInfo.get(marker);
    if (stop != null) {
        LayoutInflater inflater = (LayoutInflater) context.getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        view = inflater.inflate(R.layout.item_stop_marker_info, null);

        TextView iD = (TextView) view.findViewById(R.id.iD);
        TextView Amount = (TextView) view.findViewById(R.id.Amount);
        TextView Date = (TextView) view.findViewById(R.id.Date);



        for (int i = 0; i < stopsMarkersInfo.size(); i++) {

         }

        try {
            iD.setText(stop.getString("iD"));
            Amount.setText(stop.getString("Amount"));
            Date.setText(stop.getString("Date"));


        } catch (JSONException e) {
            e.printStackTrace();
        }


    }
    return view;
  }
  }

marker_dialog.xml:

  <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/myMarker"
   android:layout_width="100dp"
   android:layout_height="wrap_content"
   android:background="@android:color/transparent"
   android:orientation="vertical">
   <ImageView
    android:layout_width="50dp"
    android:layout_height="60dp"
    android:layout_gravity="center_horizontal"
    android:src="@drawable/ic_markericon" />
  </LinearLayout>

item_stop_marker_info.xml : Declare all the options you want in your marker

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:background="@drawable/roundlayout">

  <TextView
    android:id="@+id/iD"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_toRightOf="@+id/MName"
    android:text="iD"
    android:textColor="@color/background"
    android:textSize="13dp" />

<TextView
    android:layout_marginRight="10dp"
    android:id="@+id/Amount"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Amount"
    android:textColor="@color/background"
    android:textSize="13dp" />
  </RelativeLayout>
