我目前正在尝试使用地图框导航
我做了什么：我的问题是：如何将起点定义为位置引擎？
你知道如何继续吗？
我的代码：
@Override

super.onCreate(savedInstanceState);
// Mapbox access token is configured here. This needs to be called either in your application
// object or in the same activity which contains the mapview.
Mapbox.getInstance(this, getString(R.string.access_token));
// This contains the MapView in XML and needs to be called after the access token is configured.
setContentView(R.layout.activity_test);
// Initialize list of Position objects and add the origin Position to the list
mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

// ActivityCompat#requestPermissions

// for ActivityCompat#requestPermissions for more details.
