您可以使用我的richmaps库：https : //github.com/antoniocarlon/richmaps

您可以像这样轻松地创建渐变折线：

RichPolylineOptions polylineOpts = new RichPolylineOptions(null)
        .zIndex(3) // zIndex represents the position of the polyline on the RichLayer
        .strokeWidth(15)
        .strokeColor(Color.YELLOW) // Set the polyline base color
        .linearGradient(true)
        .add(new RichPoint(new LatLng(40.22987, -3.95931)).color(Color.RED)) // Set color for some vertices
        .add(new RichPoint(new LatLng(40.23109, -3.95926)))
        .add(new RichPoint(new LatLng(40.23063, -3.95837)).color(Color.RED))
        .add(new RichPoint(new LatLng(40.23169, -3.95809)))
        .add(new RichPoint(new LatLng(40.23093, -3.95705)))
        .add(new RichPoint(new LatLng(40.23023, -3.95626)));
RichPolyline polyline = polylineOpts.build();
polyline.add(new RichPoint(new LatLng(40.23163, -3.95602)).color(Color.CYAN)); // RichPoint added after the creation of the RichPolyline
richLayer.addShape(polyline);
