我只想在选定地图标记时更改其图标。
我在片段类中实现了GoogleMap.onMarkerclickListener类。
public class MapFragment extends SupportMapFragment implements GoogleMap.OnMarkerClickListener{
....
@Override
public boolean onMarkerClick(Marker marker) {
marker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.placemarker_pressed));
return false;
}
}
单击时会更改标记图标。如果未选中,如何将其设置回原始图标?
最佳答案
同时实现googlemap.onmaclicklistener接口并创建一个私有变量来存储当前选定的标记:
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;
}
