我想在搜索餐馆或某个地方时使用Google提供的信息
我尝试在点击Google地图中的标记时启动活动
所以使用onMarkerClick，但它只有我需要的名称，地址，地点ID
@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;
}
如何获取该位置的电话号码，评级和照片等其他信息？

您希望在标记信息窗口中显示更多数据，因此您需要在创建时将一些数据放入标记中。您应该创建一些类似的新内容： 1.首先创建一个哈希映射来放置值。
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);
当你在谷歌地图信息窗口设置列表器时，它返回标记对象get marker.getsnippet，它返回hashmap类型字符串，根据此代码将其转换为单个键值：
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;
}
这将有助于从字符串hashmap中获取键值，如下所示：
getMarkerDetails(marker).get("userName").toString();
这将返回标记＆＃34;用户名＆＃34;数据，在任何需要的地方使用。

试试这个自定义标记的完整示例。
地图活动：
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()));
}
自定义适配器类：
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： 在标记中声明所需的所有选项
<?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: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"

</RelativeLayout>
