Example 3 with BoundingBox

use of org.osmdroid.util.BoundingBox in project collect by opendatakit.

the class OsmDroidMapFragment method zoomToBoundingBox.

            // zooming by the correct amount but leaving the bounding box
            // off-center, or centering correctly but not zooming in enough.
            // Adding a 100-ms delay avoids the problem most of the time, but
            // not always; it's here because the old GeoShapeOsmMapActivity
            // did it, not because it's known to be the best solution.
            final BoundingBox box = BoundingBox.fromGeoPoints(geoPoints).increaseByScale((float) (1 / scaleFactor));
            new Handler().postDelayed(() -> map.zoomToBoundingBox(box, animate), 100);
