android - 可以删除 googlemap 上图标(项目)的阴影吗？

Question

我有一张 Google map ，上面有这些项目:

drawable3 = this.getResources().getDrawable(R.drawable.trazeicon);

但 Android 会自动在 map 上绘制图像 trazeicon 的阴影，而我不想有那个阴影。

如何删除它？

我收到错误:语法错误，插入“}”以完成 ClassBody

完整代码如下:

package com.GPSLoc;

import java.util.ArrayList;

import android.app.AlertDialog;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Rect;
import android.graphics.drawable.Drawable;

import com.google.android.maps.ItemizedOverlay;
import com.google.android.maps.MapView;
import com.google.android.maps.OverlayItem;

public class MyItemizedOverlay extends ItemizedOverlay {

    
    private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>();
    private Context mContext;
    
    public MyItemizedOverlay(Drawable defaultMarker) {
        super(boundCenterBottom(defaultMarker));
    }

    protected OverlayItem createItem(int i) {
      return mOverlays.get(i);
    }

    public int size() {
      return mOverlays.size();
    }
    
    public void addOverlay(OverlayItem overlay) {
        mOverlays.add(overlay);
        populate();
    }
    
    public MyItemizedOverlay(Drawable defaultMarker, Context context) {
          //super(defaultMarker);
          super(boundCenterBottom(defaultMarker));
          mContext = context;
    }
    public void clear()
    {
        mOverlays.clear();
    }
    
    protected boolean onTap(int index) {
      OverlayItem item = mOverlays.get(index);
      AlertDialog.Builder dialog = new AlertDialog.Builder(mContext);
      dialog.setTitle(item.getTitle());
      dialog.setMessage(item.getSnippet());
      dialog.show();
      return true;
    }
    
    public void draw(Canvas canvas, MapView mapView, boolean shadow)
    {
        if(!shadow)
        {
            super.draw(canvas, mapView, false);
        }
    }
}

扩展 ItemizedOverlay 时需要覆盖 draw() 方法。像这样:

public class MyItemizedOverlay extends ItemizedOverlay {
    @Override
    public void draw(Canvas canvas, MapView mapView, boolean shadow) {
        if(!shadow) {
            super.draw(canvas, mapView, false);
        }
    }
    ....
}
