and i need like this in overlay and calling video from some other file can
any one of you provide solution for this
// Having an EventOverlay and add events to it
// EventOverlayItem will have event location as context
// EventOverlay will contain onTap or onClick
// get location from context
// get feeds
// add feeds to the FeedOverlay
// then invalidate mapview
// addItem will take location as argument
// Have a FeedOverlay and add feeds to it
// FeedOverlay will contain onTap or onClick will get us to the feed
video
// FeedOverlayItem will have the filename as context
// need to pass a URI - for now just pass the file name
// filename should be argument to every FeedOverlayItem
// addItem method will take location and filename as argument
// The below should be part of FeedOverlay
// String filename = "famous.3gp";
// get view switcher using findViewById
// vswitcher.showNext();
// get the video view using findViewById
// same sequence as displayVideo
// get URI for file, set Video URI, start
// call setVideoURI with appropriate filename
