多个InfoWindows Android Maps V2 [英] Multiple InfoWindows Android Maps V2

问题描述

所以我的应用程序要求我为某个总线创建一个路由。我完成了这一工作，并为标记创建了一个自定义信息窗口。现在，我被要求添加一个功能，在该功能中我需要在标记周围的地图POI（兴趣点）上显示。我已经成功创建了这个。但是，我想为这些POI标记提供一个不同的信息窗口。

这是我的第一个信息窗口：

  public class InfoAdapter实现GoogleMap.InfoWindowAdapter {
 LayoutInflater inflater = null; 
 private TextView textViewstopName; 
私人TextView到达时间; 
 public InfoAdapter（LayoutInflater inflater）{
 this.inflater = inflater; 
} 
 @Override 
 public View getInfoWindow（Marker marker）{
 View v = inflater.inflate（R.layout.businfo_layout，null）; 
 if（marker！= null）{
 textViewstopName =（TextView）v.findViewById（R.id.businfo）; 
 textViewstopName.setText（marker.getTitle（））; 
 arrivalTime =（TextView）v.findViewById（R.id.arrivalinfo）; 
 arrivalTime.setText（marker.getSnippet（））; 
} 
 return（v）; 
} 
 @Override 
 public View getInfoContents（Marker marker）{
 return（null）; 
 
 
 $ / code $ / pre 
 
这里是我的第二个（我想要现在为POI默认一个）：
  public class PlacesAdapter implements GoogleMap.InfoWindowAdapter {
 LayoutInflater inflater = null ; 
 public PlacesAdapter（LayoutInflater inflater）{
 this.inflater = inflater; 
} 
 @Override 
 public View getInfoWindow（Marker marker）{
 return null; 
} 
 
 @Override 
 public View getInfoContents（Marker marker）{
 return null; 
 
 
  
这是我称之为第一个的地方： p> 
 
 
  private void SetupStopMarkers（）{
 map.setInfoWindowAdapter（new InfoAdapter（getLayoutInflater（）））; 
 addMarkersToMap（markerPoints）; 
 
 $ / code> 
这里是我称之为第二个的地方：
 
 
  else {
 map.setInfoWindowAdapter（new PlacesAdapter（getLayoutInflater（）））; 
 ... 
} 
  
我的info_layout：
 < RelativeLayout xmlns：android =http://schemas.android.com/apk/res/android
 android：layout_width = match_parent
 android：layout_height =match_parent
 android：orientation =horizo​​ntal
 android：weightSum =1
 android：background =@ drawable / businfo_dialog > 
 
< ImageView 
 android：id =@ + id / busicon
 android：layout_width =30dp
 android：layout_height =30dp
 android：src =@ drawable / busstop_icon/> 
< ImageView 
 android：id =@ + id / clockicon

 android：paddingLeft =10dp
 android：paddingRight = 10dp
 android：textColor =＃0099cc
 android：layout_centerVertical =true
 android：layout_centerHorizo​​ntal =true
 android：text =@ string / more_info /> 
< TextView 
 android：id =@ + id / eta_i
 android：layout_width =wrap_content
 android：layout_height =wrap_content
 android： layout_toRightOf =@ + id / arrivalinfo
 android：layout_toEndOf =@ + id / arrivalinfo
 android：paddingLeft =5dp
 android：paddingTop =5dp
 android：layout_alignTop =@ + id / arrivalinfo
 android：text =ETA：
 android：textStyle =bold
 android：textColor =＃FFFFFFFF/> 
< / RelativeLayout> 
  
但是在调用第二个信息窗口之后，地图中的每个标记都变为第二个信息窗口。有没有办法做到这一点？任何帮助表示感谢。
解决方案
明白了。所以要获得多个Info窗口，我必须得到与标记对应的标记ID。所以我创建了一个ArrayList，它接受标记的id。
  ArrayList< String> markerPlaces = new ArrayList<>（）; 
  
然后我将这些标记添加到地图中填充它：
  Marker marker = map.addMarker（new MarkerOptions（）。position（position）
 .title（venuesfound.get（i）.getName（）） 
 .snippet（\\\
Open：+ venuesfound.get（i）.getOpenNow（）
 +\\\
（+ venuesfound.get（i）.getCategory（）+） ）
 .icon（BitmapDescriptorFactory.fromResource（R.drawable.measle_blue）））; 
 markerPlaces.add（marker.getId（））; 
  
然后在InfoAdapter上，我添加了一个条件，如果标记ID在ArrayList中，I创建，然后放入不同的inflater。
  public class InfoAdapter implements GoogleMap.InfoWindowAdapter {
 LayoutInflater inflater = null; 
 private TextView textViewstopName; 
私人TextView到达时间; 
 public InfoAdapter（LayoutInflater inflater）{
 this.inflater = inflater; （标记符！=空）{
 if（markerPlaces.containsKey（marker.getId（））
 @Override 
 public View getInfoWindow（Marker marker）{
 if ））{
 ... //在这里添加新的充气器。 
} //检查标记是否是位置标记或POI标记的一部分。 
 else {
 View v = inflater.inflate（R.layout.businfo_layout，null）; 
 textViewstopName =（TextView）v.findViewById（R.id.businfo）; 
 textViewstopName.setText（marker.getTitle（））; 
 arrivalTime =（TextView）v.findViewById（R.id.arrivalinfo）; 
 arrivalTime.setText（marker.getSnippet（））; 
 return（v）; 
} 
} 
返回null; 
} 
 @Override 
 public View getInfoContents（Marker marker）{
 return（null）; 
} 
} 
  
谢谢大家的帮助！这当然让我想到了！
 
So my application requires me to create a route for a certain bus. I have accomplished this and have created a custom info window for the marker. Now, I was asked to add a feature in which I need to show on the map POIs (points of interests) around the marker. I have successfully created this. However, I want a different Info window for these POI markers.

Here is my first info window:
    public class InfoAdapter implements GoogleMap.InfoWindowAdapter {
    LayoutInflater inflater = null;
    private TextView textViewstopName;
    private TextView arrivalTime;
    public InfoAdapter(LayoutInflater inflater) {
        this.inflater = inflater;
    }
    @Override
    public View getInfoWindow(Marker marker) {
        View v = inflater.inflate(R.layout.businfo_layout, null);
        if (marker != null) {
            textViewstopName = (TextView) v.findViewById(R.id.businfo);
            textViewstopName.setText(marker.getTitle());
            arrivalTime = (TextView) v.findViewById(R.id.arrivalinfo);
            arrivalTime.setText(marker.getSnippet());
        }
        return (v);
    }
    @Override
    public View getInfoContents(Marker marker) {
        return (null);
    }
}
And here is my second one (I wanted to have to default one for the POIs for now):
    public class PlacesAdapter implements GoogleMap.InfoWindowAdapter{
    LayoutInflater inflater = null;
    public PlacesAdapter(LayoutInflater inflater) {
        this.inflater = inflater;
    }
    @Override
    public View getInfoWindow(Marker marker) {
        return null;
    }

    @Override
    public View getInfoContents(Marker marker) {
        return null;
    }
}
Here is where I called the first one:
    private void SetupStopMarkers(){
    map.setInfoWindowAdapter(new InfoAdapter(getLayoutInflater()));
    addMarkersToMap(markerPoints);
}
Here is where I called the second one:
else{
            map.setInfoWindowAdapter(new PlacesAdapter(getLayoutInflater()));
    ...
    }
My info_layout:
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="1"
android:background="@drawable/businfo_dialog">

<ImageView
    android:id="@+id/busicon"

    android:layout_width="30dp"

    android:layout_alignParentLeft="true"
    android:paddingLeft="5dp"
    android:src="@drawable/clock"
    android:paddingBottom="10dp"/>

<TextView

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="#FFFFFFFF"
    android:drawablePadding="10dp"

    android:paddingRight="10dp"
    android:paddingTop="5dp"/>

    android:layout_height="wrap_content"
    android:layout_below="@id/arrivalinfo"
    android:paddingTop="5dp"
    android:paddingBottom="35dp"
    android:paddingLeft="10dp"
    android:paddingRight="10dp"
    android:textColor="#0099cc"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:text="@string/more_info"/>
<TextView
    android:id="@+id/eta_i"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toRightOf="@+id/arrivalinfo"
    android:layout_toEndOf="@+id/arrivalinfo"
    android:paddingLeft="5dp"
    android:paddingTop="5dp"
    android:layout_alignTop="@+id/arrivalinfo"
    android:text="ETA:"
    android:textStyle="bold"
    android:textColor="#FFFFFFFF"/>
    </RelativeLayout>
But after calling the second info window, every marker in the map changes to that second info window.  Is there a way to do this? Any help is appreciated.
解决方案
Got it. So to get multiple Info windows, I had to get the marker ids corresponding to the markers. So I created a ArrayList that takes in the "id" of the marker.
    ArrayList<String> markerPlaces = new ArrayList<>();
I then populated it as I add the markers to the map:
    Marker marker = map.addMarker(new MarkerOptions().position(position)
                        .title(venuesfound.get(i).getName())
                        .snippet("\nOpen: " + venuesfound.get(i).getOpenNow()
                                + "\n(" + venuesfound.get(i).getCategory() + ")")
                        .icon(BitmapDescriptorFactory.fromResource(R.drawable.measle_blue)));
                markerPlaces.add(marker.getId());        
Then on the InfoAdapter, I just added a condition that if the marker id is in the ArrayList that I created, then put in a different inflater.
    public class InfoAdapter implements GoogleMap.InfoWindowAdapter {
    LayoutInflater inflater = null;
    private TextView textViewstopName;
    private TextView arrivalTime;
    public InfoAdapter(LayoutInflater inflater) {
        this.inflater = inflater;
    }
    @Override
    public View getInfoWindow(Marker marker) {
        if (marker != null) {
            if(markerPlaces.containsKey(marker.getId())) {
            ... //Add new inflater here.
            } //checks if the marker is part of the Position marker or POI marker.
            else{
                View v = inflater.inflate(R.layout.businfo_layout, null);
                textViewstopName = (TextView) v.findViewById(R.id.businfo);
                textViewstopName.setText(marker.getTitle());
                arrivalTime = (TextView) v.findViewById(R.id.arrivalinfo);
                arrivalTime.setText(marker.getSnippet());
                return (v);
            }
        }
        return null;
    }
    @Override
    public View getInfoContents(Marker marker) {
        return (null);
    }
}
Thank you all for the help! It certainly got me thinking!
