图像地图覆盖边框采用了android与 [英] Image with border in map overlay using android

问题描述

我显示这个链接，但答案仅仅只显示气球。

带有边框作为地图叠加 <图片/ p>

不过，我发现就像显示影像边框....筛选。

如果任何一个有关于如何做到这一点任何想法，请帮助我。

我做的地图显示3-5的图像。但现在我只想显示与边界图像。

先谢谢了。

解决方案

这里是一些code绘制一个圆：

 私有类ProximityOverlay扩展覆盖{    公共无效画（油画画布，MapView类MapView类，布尔B）{
        //画一些东西在这里，如
        涂料粉刷=新的油漆（）;
        paint.setAntiAlias​​（真）;
        paint.setStrokeWidth（2.0F）;
        双纬度= location.getLatitude（）;
        双经度= location.getLongitude（）;
        投影投影= MapView.getProjection（）在;
        GeoPoint的leftGeo =新的GeoPoint（（int）的（纬度* 1e6个电子），
                （中间体）（经度* 1e6个电子））;
        点左=新点（）;
        projection.toPixels（leftGeo左）;        paint.setColor（Color.parseColor（＃00CCFF））;
        paint.setStyle（Style.FILL）;
        canvas.drawCircle（left.x，left.y，9，漆）;
        paint.setColor（Color.parseColor（＃003399））;
        paint.setStyle（Style.STROKE）;
        canvas.drawCircle（left.x，left.y，10，漆）;    }
 

您可以修改它画一个黑色矩形：

  canvas.drawRect（左，上，右，下，涂料）;

解决方案

here is some code that draws a circle:

private class ProximityOverlay extends Overlay {

    public void draw(Canvas canvas, MapView mapview, boolean b) {
        // draw some stuff in here, like
        Paint paint = new Paint();
        paint.setAntiAlias(true);
        paint.setStrokeWidth(2.0f);
        double latitude = location.getLatitude();
        double longitude = location.getLongitude();
        Projection projection = mapView.getProjection();
        GeoPoint leftGeo = new GeoPoint((int) (latitude * 1e6),
                (int) (longitude * 1e6));
        Point left = new Point();
        projection.toPixels(leftGeo, left);

        paint.setColor(Color.parseColor("#00CCFF"));
        paint.setStyle(Style.FILL);
        canvas.drawCircle(left.x, left.y, 9, paint);
        paint.setColor(Color.parseColor("#003399"));
        paint.setStyle(Style.STROKE);
        canvas.drawCircle(left.x, left.y, 10, paint);



    }

you can modify it to draw a black rectangle:

canvas.drawRect(left, top, right, bottom, paint);
