我加载了 Indoor Atlas 平面图图像,但我如何在该图像上显示我的位置。此外,此图像是静态的,请帮忙。

加载平面图的代码如下。

public void loadFloorPlanImage(FloorPlan floorPlan) 
{
    BitmapFactory.Options options = createBitmapOptions(floorPlan);
    FutureResult<Bitmap> result = mIndoorAtlas.fetchFloorPlanImage(floorPlan,options);
    result.setCallback(new ResultCallback<Bitmap>() {
        @Override
        public void onResult(final Bitmap result) {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    ImageView imageView = (ImageView)    findViewById(R.id.imageView);
                    imageView.setImageBitmap(result);
                }
        });
        }
    });
}

我不时得到位置,我只是在 ImageView 上标记该位置,我的代码是..

公共无效 onServiceUpdate(ServiceState 状态){

       double x1 = state.getMetricPoint().getX();
        double y1 = state.getMetricPoint().getY();
        float x = (float) x1;
        float y = (float) y1;

        //Paint paint = new Paint();
        Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
        paint.setAntiAlias(true);
        paint.setColor(Color.RED);

        Bitmap workingBitmap = Bitmap.createBitmap(image);
        Bitmap mutableBitmap = workingBitmap.copy(Bitmap.Config.ARGB_8888, true);

        Canvas canvas = new Canvas(mutableBitmap);
       // canvas.drawCircle(x, y, 100, paint);
        canvas.drawCircle(50, 50, 10, paint);

        imageView.setAdjustViewBounds(true);
        imageView.setImageBitmap(image);

}

但它不起作用。请帮忙谢谢
