Method Detail

• invalidateContentPadding

  @Deprecated
  public void invalidateContentPadding​()

  Deprecated. unused

• getProjectedMetersForLatLng

  @NonNull
  public ProjectedMeters getProjectedMetersForLatLng​(@NonNull
                                                     LatLng latLng)

  Returns the spherical Mercator projected meters for a LatLng.

• getLatLngForProjectedMeters

  @NonNull
  public LatLng getLatLngForProjectedMeters​(@NonNull
                                            ProjectedMeters projectedMeters)

  Returns the LatLng for a spherical Mercator projected meters.

• getMetersPerPixelAtLatitude

  public double getMetersPerPixelAtLatitude​(double latitude)

  Returns the distance spanned by one pixel at the specified latitude and current zoom level.

  The distance between pixels decreases as the latitude approaches the poles. This relationship parallels the relationship between longitudinal coordinates at different latitudes.

  Parameters:

  latitude - The latitude for which to return the value.

  Returns:

  The distance measured in meters.

• fromScreenLocation

  @NonNull
  public LatLng fromScreenLocation​(@NonNull
                                   android.graphics.PointF point)

  Returns the geographic location that corresponds to a screen location. The screen location is specified in screen pixels (not display pixels) relative to the top left of the map (not the top left of the whole screen).

  Parameters:

  point - A Point on the screen in screen pixels.

  Returns:

  The LatLng corresponding to the point on the screen, or null if the ray through the given screen point does not intersect the ground plane.

• fromScreenLocations

  public void fromScreenLocations​(@NonNull
                                  double[] input,
                                  @NonNull
                                  double[] output)

  Returns the geographic locations that corresponds to screen locations. The screen locations are specified in screen pixels (not display pixels) relative to the top left of the map (not the top left of the whole screen).

  Parameters:

  input - an array of input values representing screen coordinates

  output - an array of output values representing geographic locations

• getVisibleRegion

  @NonNull
  public VisibleRegion getVisibleRegion​()

  Gets a projection of the viewing frustum for converting between screen coordinates and geo-latitude/longitude coordinates.

  This method ignores the content padding.

  Returns:

  The projection of the viewing frustum in its current state.

• getVisibleRegion

  @NonNull
  public VisibleRegion getVisibleRegion​(boolean ignorePadding)

  Gets a projection of the viewing frustum for converting between screen coordinates and geo-latitude/longitude coordinates.

  Parameters:

  ignorePadding - True if the padding should be ignored, false if the returned region should be reduced by the padding.

  Returns:

  The projection of the viewing frustum in its current state.

• getVisibleCoordinateBounds

  public void getVisibleCoordinateBounds​(@NonNull
                                         double[] bounds)

  Gets a projection of the viewing frustum for converting between screen coordinates and geo-latitude/longitude coordinate bounds.

  This method ignores the content padding.

  Parameters:

  bounds - an array of 4 output values representing bounds(in the order of latNorth, lonEast, latSouth, lonWest).

• toScreenLocation

  @NonNull
  public android.graphics.PointF toScreenLocation​(@NonNull
                                                  LatLng location)

  Returns a screen location that corresponds to a geographical coordinate (LatLng). The screen location is in screen pixels (not display pixels) relative to the top left of the map (not of the whole screen).

  Parameters:

  location - A LatLng on the map to convert to a screen location.

  Returns:

  A Point representing the screen location in screen pixels.

• toScreenLocations

  public void toScreenLocations​(@NonNull
                                double[] input,
                                @NonNull
                                double[] output)

  Returns a screen locations that corresponds to a geographical coordinates. The screen locations are in screen pixels (not display pixels) relative to the top left of the map (not of the whole screen).

  Parameters:

  input - an array of input values representing geographic locations

  output - an array of output values representing screen coordinates

• calculateZoom

  public double calculateZoom​(float minScale)

  Calculates a zoom level based on minimum scale and current scale from MapView

  Parameters:

  minScale - The minimum scale to calculate the zoom level.

  Returns:

  zoom level that fits the MapView.
