((MapView) findViewById(R.id.my_map_view)).setTraffic(true);

public void setTraffic(boolean isEnabled) Control whether traffic is shown on the map. This is incompatible with Street View indicators, so they will be deactivated if necessary. They can be drawn over map tiles or over satellite tiles; however, they are optimized for map tiles. Parameters: on - If true, turn traffic lines on. If false, turn them off.
