更改选中 Google 地图标记的图标
Changing the icon of Google Maps marker while it's selected
我只想在地图标记被选中时更改它的图标。
我在我的 Fragment class 中实现了 GoogleMap.OnMarkerClickListener class。
public class MapFragment extends SupportMapFragment implements GoogleMap.OnMarkerClickListener{
....
@Override
public boolean onMarkerClick(Marker marker) {
marker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.placemarker_pressed));
return false;
}
}
单击时更改标记图标。未选中时如何设置回原来的图标?
同时实现GoogleMap.OnMapClickListener接口并创建一个私有变量来存储当前选择的标记:
private Marker mSelectedMarker;
然后:
@Override
public boolean onMarkerClick(Marker marker) {
if (null != mSelectedMarker) {
mSelectedMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.placemarker));
}
mSelectedMarker = marker;
mSelectedMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.placemarker_pressed));
return false;
}
@Override
public boolean onMapClick(LatLng latLng) {
if(null != mSelectedMarker) {
mSelectedMarker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.placemarker));
}
mSelectedMarker = null;
}
