【问题描述】：
我正在尝试实现地图活动。我需要使用谷歌地图 SDK 显示附近的地方。我不知道如何使用 Google Map SDK，因为我是初学者。
我尝试了许多使用 HTTP URL 的教程。我需要使用谷歌地图 SDK。使用指定半径的 ATM、BANK 等关键字搜索附近的地方。
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mMap;
private FusedLocationProviderClient fusedLocationClient;
double C_Latitude, C_Longitude;
PlacesClient placesClient;
private static final int MY_PERMISSIONS_REQUEST_READ_CONTACTS = 1;
String keyword="atm";
String radius="1000";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
Places.initialize(getApplicationContext(),"@string/key");
placesClient = Places.createClient(this);
fusedLocationClient = LocationServices.getFusedLocationProviderClient(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
if (ContextCompat.checkSelfPermission(this,
Manifest.permission.ACCESS_FINE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,
Manifest.permission.ACCESS_FINE_LOCATION)) {
} else {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, MY_PERMISSIONS_REQUEST_READ_CONTACTS);
}
} else {
fusedLocationClient.getLastLocation().addOnSuccessListener(this, new OnSuccessListener<Location>() {
@Override
public void onSuccess(Location location) {
if (location != null) {
C_Latitude = location.getLatitude();
C_Longitude = location.getLongitude();
LatLng CurrntLocation = new LatLng(C_Latitude, C_Longitude);
CameraUpdate yourLocation = CameraUpdateFactory.newLatLngZoom(CurrntLocation, 19); //zoom
mMap.addMarker(new MarkerOptions().position(CurrntLocation).title("Current Position")); //marker
mMap.animateCamera(yourLocation);
GetNearbyPlace();
}
}
});
}
}
private void GetNearbyPlace() {
}
}
