Class Polyline

java.lang.Object

com.codename1.maps.Polyline
public final class Polyline extends MapObject

A connected sequence of line segments drawn on a map. Add one through MapSurface.addPolyline(Polyline).

A polyline joins the vertices you give it with straight segments; it knows nothing about roads. To draw a route that follows the road network, ask a routing service for the road geometry and draw that -- see Routing, or decode a geometry you fetched yourself with fromEncoded(String).

  • Constructor Details

    • Polyline

      public Polyline()
      Creates an empty polyline; append vertices with addPoint(LatLng).

    • Polyline

      public Polyline(LatLng[] pts)
      Creates a polyline through the supplied vertices (defensively copied).

  • Method Details

    • fromEncoded

      public static Polyline fromEncoded(String encoded)
      Creates a polyline from an encoded polyline geometry at PolylineCodec's default precision -- the shape virtually every directions API returns for a route.

    • fromEncoded

      public static Polyline fromEncoded(String encoded, int precision)

      Creates a polyline from an encoded polyline geometry at an explicit decimal precision (5 for the classic format, 6 for polyline6).

      Throws IllegalArgumentException when precision falls outside 1 to 10; a precision that cannot scale coordinates sensibly would otherwise decode into a line drawn in the wrong place. See PolylineCodec.

    • addPoint

      public Polyline addPoint(LatLng point)
      Appends a vertex.

    • getPoints

      public List getPoints()
      The live list of vertices (LatLng).

    • getStrokeColor

      public int getStrokeColor()
      The stroke color as 0xRRGGBB.

    • setStrokeColor

      public Polyline setStrokeColor(int strokeColor)
      Sets the stroke color as 0xRRGGBB.

    • getStrokeWidth

      public int getStrokeWidth()
      The stroke width in pixels.

    • setStrokeWidth

      public Polyline setStrokeWidth(int strokeWidth)
      Sets the stroke width in pixels.

    • getStrokeAlpha

      public int getStrokeAlpha()
      The stroke opacity in [0,255].

    • setStrokeAlpha

      public Polyline setStrokeAlpha(int strokeAlpha)
      Sets the stroke opacity in [0,255].

    • isVisible

      public boolean isVisible()
      Whether the polyline is rendered.

    • setVisible

      public Polyline setVisible(boolean visible)
      Shows or hides the polyline.
