MapView as a layout for native Android views?

[schildbach]

The old Google Maps v1 library had this wonderful feature where MapView would act as a geo-coordinate-aware layout. You would add views to the layout and they would follow all map panning and zooming.

mapView.addView(view, new MapView.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT,
    point, 
MapView.LayoutParams.BOTTOM_CENTER));

Here is how the view could look. Other than markers etc. it contains native Android buttons.

Is something like this planned for mapsforge?

Agreed that it would be a useful feature to have in Mapsforge.
I have tried it in the past, not without issues at pan / zoom and neglected it.

Experiments could start as always in Samples app.

This is the next feature I will work on shortly, if no one else beats me at it.

Thanks, merged with some improvements.

• View overlays are not handled properly during zoom scale animation
• Osmdroid similar implementation has also additional x/y offsets for the alignment location (might be unnecessary)

[schildbach]

Thanks for merging.
Zoom scale animations: this will be fixed once we do proper zoom animations. Currently zoom animations are very local to MapViewPosition. Also see my comment about that on #688.
Offsets: if there is a usecase, we can easily add that. I never had one, as I was always anchoring to one of the 9 standard alignment points.
