java - 在 Google map 上绘制我的路线

Question

我想在android中的GoogleMap上绘制我的路径..当我移动Forword时，应该绘制折线...我读了一些关于谷歌地图和json解析器的教程，但在这种情况下，我们只绘制从开始到目的地的路径。 ..我还阅读了在 MapView 上绘制 Overlay 的教程..但我想在 GooglMap 类上绘制它...MapView OverLay 的代码如下，但它不适用于 GooglMap

package com.example.PublicSafety;
import java.util.ArrayList;
import java.util.List;
import com.google.android.maps.Overlay;
import android.graphics.Color;
import android.graphics.Paint;
import android.location.Location;

public class RouteOverlay extends Overlay{
    private List<Location> locations;
    private Paint pathPaint;
    private Paint postionPaint;
    public RouteOverlay() {
        pathPaint = new Paint();
        pathPaint.setAntiAlias(true);
        pathPaint.setColor(Color.RED);
        pathPaint.setStyle(Paint.Style.STROKE);
        pathPaint.setStrokeWidth(5);
        locations = new ArrayList<Location>();

        postionPaint = new Paint();
        postionPaint.setAntiAlias(true);
        postionPaint.setStyle(Paint.Style.FILL);
    }


}
