Question

标记未显示在我的地图上。我在onMapReady类中编写了代码，但是似乎没有人可以帮助我。我不知道问题所在。我尝试了很多次。

public class Home extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener, OnMapReadyCallback,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener,
    LocationListener{

private GoogleMap mMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.addDrawerListener(toggle);
    toggle.syncState();

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    //Map
    mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    //Add Marker
    LatLng kilin = new LatLng(33.6518, 73.1566);
    mMap.addMarker(new MarkerOptions().position(kilin).title("Stop")).setIcon(BitmapDescriptorFactory.fromResource(R.drawable.car));

}

}

您的代码应该可以正常工作，请确保图标不要太小或太透明或有其他东西，添加标记后请致电mMap.moveCamera(CameraUpdateFactory.newLatLng(kilin));以确保您在正确的位置查找它
