Question

我正在创建MapView应用程序，我必须在其中显示其URL来自服务器的商业徽标，带有黑色边框。我在MapView上显示了商业标识，但是我可以在商业标识周围绘制边框的方式和位置。我见过绘制圆圈的代码：

    @Override
    public void draw(Canvas canvas, MapView mapView, boolean shadow) {
    Paint paint = new Paint();
    paint.setAntiAlias(true);
    paint.setStrokeWidth(2.0f);
    double latitude = 37.819586;
    double longitude = -122.478532;
    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, 19, paint);
    canvas.drawRect(left.x,left.y,left.x, left.y, paint);

    super.draw(canvas, mapView, false);
}

这只是绘制圆圈。我想在方形图像周围绘制边框。

Answer 1

您正在为绘制rect传递相同的值，即（左，上，右，下）它应该是

drawRect (float left, float top, float right, float bottom, Paint paint)

参考API docs

你正在传递canvas.drawRect（left.x，left.y， left.x，left.y ，paint）;到右边和底部
