问题 I'm trying to draw a custom gps-location icon. I'm using MapView and have created a class MyLocationArrow that extends MyLocationOverlay. I override drawMyLocation() and draw a point at 100,100. But this is the coordinates on screen. How do I get the screen-coordinates from the current GPS-location? 回答1: You can use android.graphics.Point toPixels(GeoPoint in, android.graphics.Point out) Converts the given GeoPoint to onscreen pixel coordinates, relative to the top-left of the MapView that

问题 I've poured over the docs and haven't been able to figure this out. Is it even possible? Please see this 回答1: It looks like the correct mechanism to do this is to extend MyLocationOverlay then override the drawMyLocation() protected method. The following uses an arrow to show where "you" are and which way "you" are pointing: package com.example; import android.content.Context; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.Canvas; import android

问题 I am using MapView to show current location of a user on a Map. To update the location while the user is on the move, I have to a choice: I can use MyLocationOverlay to draw the current location and extend it to allow tracking of the users location on the move and to have custom marker. The problem with MyLocationOverlay is that I cannot control the frequency with which the device requests the location from GPS. I am worried about the battery drain here. I can use Location Manager and

问题 Just wasted 3 hours trying to figure out why the GPS icon is still showing up in the notification bar when my map activity is paused. I've narrowed it down to having to do with the MyLocationOverlay object I'm using (I also have a LocationListener and a GpsStatus.Listener). @Override protected void onPause() { super.onPause(); manager.removeUpdates(locListener); manager.removeGpsStatusListener(statListener); myLocOverlay.disableMyLocation(); //!doesn't seem to work myLocOverlay.disableCompass

Maps V2 myLocation blue dot callback

由 China☆狼群 提交于 2019-12-01 12:58:12
I want to be able to click the blue dot (my location) that is shown on the map. Is there anyway to get a callback from that click? Thanks, Martijn One possible workaround might be drawing a Marker (with a similar icon) on top of the My Location dot so you can receive the corresponding onMarkerClick() callback. This would also require removing the marker and adding it to the new location everytime there's a location update event, which you can listen to by implementing OnMyLocationChangeListener . EDIT : the OnMyLocationChangeListener interface is now deprecated, one should use instead the new
