Google Maps API v2 Android add shape drawable as marker -

-

i've been trying add shape drawable marker icon marker want add on map.

shape looks (res/drawable/blue_circle.xml):

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="oval" >     <size         android:width="15dp"         android:height="15dp" />     <solid         android:color="@color/blue" /> </shape>

and try add marker this:

markeroptions.icon(bitmapdescriptorfactory.fromresource(r.drawable.blue_circle));

apparently nullpointer exception.

must marker icon bitmap? allowed add shapes drawables marker icons? , if yes doing wrong?

create drawable marker (res/drawable/map_dot_red.xml):

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="oval" >      <gradient         android:angle="90"         android:endcolor="#f58383"         android:startcolor="#ee6464" />      <stroke         android:width="1dp"         android:color="#a13939" />  </shape>

create bitmap drawable:

int px = getresources().getdimensionpixelsize(r.dimen.map_dot_marker_size); mdotmarkerbitmap = bitmap.createbitmap(px, px, bitmap.config.argb_8888); canvas canvas = new canvas(mdotmarkerbitmap); drawable shape = getresources().getdrawable(r.drawable.map_dot_red); shape.setbounds(0, 0, mdotmarkerbitmap.getwidth(), mdotmarkerbitmap.getheight()); shape.draw(canvas);

create marker, using bitmap:

marker marker = mmap.addmarker(new markeroptions()     .position(point)     .anchor(.5f, .5f)     .icon(bitmapdescriptorfactory.frombitmap(mdotmarkerbitmap)));

set size of marker in dimens (res/values/dimens.xml):

<resources>     <dimen name="map_dot_marker_size">12dp</dimen> </resources>
