使用android在google地图中显示多个位置

// 在布局文件中添加MapView元素
<com.google.android.gms.maps.MapView
    android:id="@+id/mapView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

// 在Activity中初始化地图
public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback {
    private GoogleMap googleMap;
    private MapView mapView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);

        mapView = findViewById(R.id.mapView);
        mapView.onCreate(savedInstanceState);
        mapView.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap map) {
        googleMap = map;

        // 设置地图视图的初始位置和缩放级别
        LatLng initialLocation = new LatLng(37.7749, -122.4194);
        googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(initialLocation, 12));

        // 添加多个位置标记
        LatLng location1 = new LatLng(37.7749, -122.4194);
        googleMap.addMarker(new MarkerOptions().position(location1).title("Marker 1"));

        LatLng location2 = new LatLng(37.7749, -122.4316);
        googleMap.addMarker(new MarkerOptions().position(location2).title("Marker 2"));

        // 添加更多位置标记...

        // 设置其他地图属性和交互方式
        googleMap.getUiSettings().setZoomControlsEnabled(true);
        googleMap.getUiSettings().setCompassEnabled(true);
        googleMap.getUiSettings().setMapToolbarEnabled(true);
        googleMap.getUiSettings().setRotateGesturesEnabled(true);
    }

    @Override
    public void onResume() {
        super.onResume();
        mapView.onResume();
    }

    @Override
    public void onPause() {
        super.onPause();
        mapView.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        mapView.onDestroy();
    }

    @Override
    public void onLowMemory() {
        super.onLowMemory();
        mapView.onLowMemory();
    }
