How to Implement draggable map like uber android, Update with change location -
how implement draggable map uber? using google maps v2. got solution referring this post , sharing complete solution here
updated latest code included change location autocomplete
complete project can found here
logic simple need framelayout , add map , marker layout inside framelayout make maker layout gravity center , latitude , longitude of centre point of map on camera change refer this answer here code create activity_maps.xml
