在Google地图中选择图标作为标记

Question

This is my code and it compiles correctly, but when I want to run the app, it shows

Unfortunately, app has stopped

This is my code:

    @Override
    public void onMapReady(GoogleMap googleMap) {
        map = googleMap;
        LatLng pp = new LatLng( 12,12 );
        MarkerOptions option = new MarkerOptions();
        option.position(pp)
                .title( "hi " )
                .snippet("for test");

        option.icon(BitmapDescriptorFactory.fromResource(R.drawable.about));

        map.addMarker( option );
        map.moveCamera( CameraUpdateFactory.newLatLng( pp ) );

When I remove this line:

option.icon(BitmapDescriptorFactory.fromResource(R.drawable.about));

it works correctly. I need to change default marker but I can't.

Answer 1

Change default marker with color in google map, please try below like this:

googleMap.addMarker(new MarkerOptions()
        .position(BROOKLYN_BRIDGE)
        .title("First Pit Stop")
        .icon(BitmapDescriptorFactory
        .defaultMarker(BitmapDescriptorFactory.HUE_GREEN)));
