我正在尝试让Google室内地图在我的应用中运行.当我在Google地图中查看具有室内信息的建筑物时,它会显示其中的地点名称.

我查找了示例Google室内地图项目,并在示例项目中显示了建筑物(但不是全部地名)中添加了新的纬度和经度.

如何使它显示与Google地图显示的信息相同的信息？

这是IndoorDemoActivity的代码

public class IndoorDemoActivity extends FragmentActivity {  private GoogleMap mMap;  private boolean showLevelPicker = true;  @OverrIDe  protected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.indoor_demo);    mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentByID(R.ID.map)).getMap();    // SFO airport//    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(37.614631, -122.385153), 18));    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(19.173036, 72.835679), 18));  }  /**   * Called when the toggle level picker button is clicked.   */  public voID onToggleLevelPicker(VIEw vIEw) {    showLevelPicker = !showLevelPicker;    mMap.getUiSettings().setIndoorLevelPickerEnabled(showLevelPicker);  }  /**   * Called when the focused building info is clicked.   */  public voID onFocusedBuildingInfo(VIEw vIEw) {    IndoorBuilding building = mMap.getFocusedBuilding();    if (building != null) {      String s = "";      for (IndoorLevel level : (List<IndoorLevel>) building.getLevels()) {        s = s + level.getname() + " ";      }      if (building.isUnderground()) {        s += "is underground";      }      setText(s);    } else {      setText("No visible building");    }  }  /**   * Called when the focused level info is clicked.   */  public voID onVisibleLevelinfo(VIEw vIEw) {    IndoorBuilding building = mMap.getFocusedBuilding();    if (building != null) {      IndoorLevel level = (IndoorLevel) building.getLevels().get(building.getActiveLevelindex());      if (level != null) {        setText(level.getname());      } else {        setText("No visible level");      }    } else {      setText("No visible building");    }  }  /**   * Called when the activate higher level is clicked.   */  public voID onHigherLevel(VIEw vIEw) {    IndoorBuilding building = mMap.getFocusedBuilding();    if (building != null) {      List<IndoorLevel> levels = building.getLevels();      if (!levels.isEmpty()) {        int currentLevel = building.getActiveLevelindex();        // The levels are in 'display order' from top to bottom,        // i.e. higher levels in the building are lower numbered in the array.        int newLevel = currentLevel - 1;        if (newLevel == -1) {          newLevel = levels.size() - 1;        }        IndoorLevel level = levels.get(newLevel);        setText("Activiating level " + level.getname());        level.activate();      } else {        setText("No levels in building");      }    } else {      setText("No visible building");    }  }  private voID setText(String message) {    TextVIEw text = (TextVIEw) findVIEwByID(R.ID.top_text);    text.setText(message);  }}

解决方法:

您在Google Maps应用中看到的标记很可能由Google Maps应用本身通过Google Places放置.您在应用程序中看到的有限标记集很可能会被烘焙到室内地图中,即“Floor Plan markers”.

据我所知,要显示其他地点信息,您必须将其与Google Places API集成在一起.然后,您可以使用它与addMarker一起查找和添加业务标记,很可能在更改级别时清除并重新添加它们.
