I Want To Move Icon From One Location Point To Another Point Where Icon Should Move One Location To Other In Android
I am working on a car tacking app. I want to move the icon to another location in android I had already tried to remove old map icon and clearing all icons and generating new icon.
Solution 1:
I assume you are using Google map marker to show the location. If so, no need to remove the marker. Instead save the marker object in a variable and update the variable whenever the location changes. Eg; marker.setPosition();
Solution 2:
privatedoublebearingBetweenLocations(LatLng latLng1, LatLng latLng2){
finaldouble PI = 3.14159;
finaldouble lat1 = latLng1.latitude * PI / 180;
finaldouble long1 = latLng1.longitude * PI / 180;
finaldouble lat2 = latLng2.latitude * PI / 180;
finaldouble long2 = latLng2.longitude * PI / 180;
finaldouble dLon = (long2 - long1);
finaldouble y = Math.sin(dLon) * Math.cos(lat2);
finaldouble x = Math.cos(lat1) * Math.sin(lat2) - Math.sin(lat1)
* Math.cos(lat2) * Math.cos(dLon);
double brng = Math.atan2(y, x);
brng = Math.toDegrees(brng);
brng = (brng + 360) % 360;
return brng;
}
Calculate the degree of rotation.And then onLocationChanged()
set the image again:
@Override
publicvoidonLocationChanged(Location location) {
if (location == null)
return;
if (mMap != null) {
if (mPositionMarker != null && mPositionMarker.isVisible()) {
mPositionMarker.remove();
}
newLatLng = new LatLng(location.getLatitude(), location.getLongitude());
if (oldLatLng != null) {
mPositionMarker = mMap.addMarker(new MarkerOptions()
.flat(true)
.anchor(0.5f, 0.5f).icon(BitmapDescriptorFactory
.fromResource(R.drawable.ic_cab_top)).rotation((float) bearingBetweenLocations(newLatLng, oldLatLng))
.position(new LatLng(location.getLatitude(), location
.getLongitude())));
animateMarker(mPositionMarker, location); // Helper method for smooth animation
mMap.animateCamera(CameraUpdateFactory.newLatLng(new LatLng(location
.getLatitude(), location.getLongitude())));
}
oldLatLng = newLatLng;
}
