android - 添加标记时自动打开 InfoWindow Google Maps v2 Android

Question

有没有办法在我们添加标记时自动打开信息窗口？使用此代码添加标记，但信息窗口仅在单击标记时打开:

myMap.addMarker(new MarkerOptions()
            .position(latLng)
            .title("Title")
            .snippet("Snippet")
            .icon(BitmapDescriptorFactory
                    .fromResource(R.drawable.marker)));

Answer 1

根据Google Maps for Android V2的文件:

An info window allows you to display information to the user when they tap on a marker on a map. By default, an info window is displayed when a user taps on a marker if the marker has a title set. Only one info window is displayed at a time. If a user clicks on another marker, the current window will be hidden and the new info window will be displayed. You can show an info window programmatically by calling showInfoWindow() on the target marker. An info window can be hidden by calling hideInfoWindow().

您可以像这样显示信息窗口:

Marker marker = myMap.addMarker(new MarkerOptions()
                     .position(latLng)
                     .title("Title")
                     .snippet("Snippet")
                     .icon(BitmapDescriptorFactory
                     .fromResource(R.drawable.marker)));

marker.showInfoWindow();
