如何在Android Google Maps v2中创建带传感器轴承的位置箭头标记？

Question

I have managed to create an arrow ImageView and get the azimuth from the sensors, after that I rotate the ImageView using setRotation() method of the View class. How I can do this for a marker using Android Google Maps v2 Markers?

Answer 1

I suggest you take a look at the android-maps-utils project from Google.

It contains

• BubbleIconFactory : Responsible for generating markers
• RotationLayout : Responsible for rotating the contents of the layout (the marker) by multiples of 90 degrees

This should give you the building blocks you need to display your arrow/marker and give it a certain rotation. You'll probably need to customize the rotationlayout a bit.

Answer 2

you can use: https://developers.google.com/maps/documentation/android/marker#rotate_a_marker

com.google.android.gms.maps.model.Marker marker = addMapMarker(camera,PrefManager.getCurrentUsername(getActivity()),
            BitmapDescriptorFactory.fromResource(R.drawable.overlay_gps_location_scanner_icon));
marker.setRotation(0);
