谷歌地图在安卓MapFragment中显示用户方向/方向

MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map_fragment);

mapFragment.getMapAsync(new OnMapReadyCallback() {
    @Override
    public void onMapReady(GoogleMap googleMap) {
        googleMap.getUiSettings().setCompassEnabled(true);
    }
});

SensorManager sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
SensorEventListener sensorEventListener = new SensorEventListener() {
    @Override
    public void onSensorChanged(SensorEvent event) {
        float azimuth = event.values[0];
        // 根据方向信息更新地图的方向
        googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(
                new CameraPosition.Builder()
                        .target(googleMap.getCameraPosition().target)
                        .bearing(azimuth)
                        .build()));
    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {
        // 精度变化时的处理
    }
};
sensorManager.registerListener(sensorEventListener, sensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION), SensorManager.SENSOR_DELAY_NORMAL);
