在Android中绘制kml坐标Google Map

Question

我正在创建一个Android应用程序来映射我们当地的山地自行车道。坐标来自KML文件。到目前为止，我已经绘制并创建了11个GeoPoints的路径。但是，我有数百个坐标来映射。这是我迄今为止所做的代码。这有效，但它非常乏味，我还有数百项工作要做。有没有更好的方法来做到这一点？有没有办法让我的覆盖层类从我的kml文件中读取坐标？任何其他想法或想法都会受到赞赏。

    super.draw(canvas, mapView, shadow); 
    Paint paint; 
    paint = new Paint(); 
    paint.setDither(true); 
    paint.setColor(Color.RED); 
    paint.setStyle(Paint.Style.FILL_AND_STROKE); 
    paint.setStrokeJoin(Paint.Join.ROUND); 
    paint.setStrokeWidth(2);

难道你不能只读KML文件，并通过点循环？
