我只是想知道我可以使用不同的信息窗口创建多个标记，在Android中的谷歌地图v2中，在我的情况下，我尝试3种不同的标记， 1.学校标记 2.方向（fromPosition） 3.方向（toPosition）
注意：nama_sma＆gt;＆gt;学校名称 ：nama_bemo＆gt;＆gt;出租车
现在，我可以显示所有这些标记，但每个标记的问题都有相同的信息窗口， 这是我的xml：
<com.example.frontend.search.MapWrapperLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map_relative_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="@+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/layout1"
class="com.google.android.gms.maps.SupportMapFragment"/>
</com.example.frontend.search.MapWrapperLayout>
nb：MapWrapperLayout是我的应用程序中自定义信息窗口的包装器
这是我的活动

问题是，3 Marker（fromPosition），（toPosition）和（School Marker）显示相同的信息窗口，任何人都可以帮助我吗？在每个标记中创建不同的信息窗口？需要任何帮助。谢谢你
答案 0 :(得分：0)
编辑：如果您希望为每个标记设置不同的信息窗口，则还必须为每个标记创建一个视图。为标记的信息窗口创建一个Map，并使用Marker id作为键，以便检查是否已创建View。
尝试这样的事情：
private Map<String,ViewGroup> infoWindows = new HashMap<String,ViewGroup>();
...
@Override
public View getInfoWindow(Marker marker) {
// get or create the infoWindows here instead of in onCreate
ViewGroup infoWindow = infoWindows.get(marker.getId());
if(infoWindow==null){
//if the info window was not yet created for this marker, create it
infoWindow = (ViewGroup)getLayoutInflater().inflate(R.layout.custom_info_window, null);
Button infoButton = (Button)infoWindow.findViewById(R.id.button2);
infoButton.setOnTouchListener(infoButtonListener2);
infoWindows.put(marker.getId(), infoWindow);
}
// set or update the texts
((TextView)infoWindow.findViewById(R.id.title)).setText(marker.getTitle());
((TextView)infoWindow.findViewById(R.id.snippet)).setText(marker.getSnippet());
//why do you need to set the marker to the listener?
infoButtonListener2.setMarker(marker);
mapWrapperLayout.setMarkerWithInfoWindow(marker, infoWindow);
return infoWindow;
}
