是否可以将触摸事件坐标用于其他活动的位图？

Question

我有一个扩展的ImageView活动，其中我有一个位图，我通过onTouchEvent触摸感兴趣的点，检索触摸点的坐标，然后围绕该点绘制一个矩形。所以这部分代码完美无缺。

public class RectActivityView extends ImageView {
private Point point;
private Paint paint = new Paint();
private static final String FILE_SUFFIX_CSV = ".csv";
public RectActivityView(Context context) {
        super(context);
}
public RectActivityView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public RectActivityView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public boolean onTouchEvent(@NonNull MotionEvent event) {

        int x = (int) event.getX();
        int y = (int) event.getY();

        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                point = new Point(x, y);
                invalidate();
                break;
            case MotionEvent.ACTION_MOVE:
                point.set(x, y);
                invalidate();
                break;
            case MotionEvent.ACTION_UP:
            //case MotionEvent.ACTION_CANCEL:
                point = new Point(x, y);
                invalidate();

                //save last touched point
                final String timeStamp2 = new SimpleDateFormat("yyyyMMdd").format(new Date());
                String timeStamp3 = new SimpleDateFormat("HHmmss").format(new Date());
                File direct = new File(Environment.getExternalStorageDirectory() + "/detectTracks/Setup");
                if (!direct.exists()) {
                direct.mkdirs();}
                String entry = timeStamp2 + "," + timeStamp3 + "," +  point.x + "," + point.y + "\n";
                File dataFile = new File(new File("/sdcard/detectTracks/Setup"), timeStamp2 + FILE_SUFFIX_CSV);
                try {
                    FileWriter logWriter = new FileWriter(dataFile, true);
                    BufferedWriter bw = new BufferedWriter(logWriter);
                    PrintWriter out = new PrintWriter(bw);
                    out.write(entry);
                    out.flush();
                    out.close();
                    //Toaster.show(this, R.string.export_data_succeeded);
                } catch (Exception e) {
                    e.printStackTrace();}
                break;
        }return true;
    }
    @Override
    protected void onDraw(@NonNull Canvas canvas) {
        super.onDraw(canvas);

        int size = 50;
        if (point != null) {
            Rect myROIouter = new Rect(point.x - size, point.y - size,point.x + size, point.y + size);
            paint.setColor(Color.TRANSPARENT);
            paint.setStyle(Paint.Style.FILL);
            paint.setAlpha(80);
            canvas.drawRect(myROIouter, paint);
            // BORDER
            paint.setStrokeWidth(5);
            paint.setColor(Color.RED);
            paint.setStyle(Paint.Style.STROKE);
            canvas.drawRect(myROIouter, paint);
           }
        }
    }

然后我将这些坐标传递给另一个活动，我想在同一个位图顶部的坐标周围画一个圆圈，就像我在扩展的ImageView中那样。我已经用位图和imageView的宽高比校正了高度和宽度，但是钢铁不能在我之前的活动中触及的确切点上绘制圆圈。这里有什么我想念的吗？

第二项活动的部分代码：

    //retrieved coordinates from .csv file
    double xROIA = Double.parseDouble(dataA[2]);
    double yROIA = Double.parseDouble(dataA[3]);
    int bmpWidth = 3036;
    int bmpHeight = 4048;
    int widthView = 1328;
    int heightView = 1770;

    double aspectWidth = bmpWidth / widthView;
    double aspectHeight = bmpHeight / heightView;

    int coorX = (int) (xROIA  * aspectWidth);
    int coorY = (int) (yROIA * aspectHeight);

    Imgproc.circle(image, point, size2/2, new Scalar(255,0,0),2);

    Bitmap imageBitmap = Bitmap.createBitmap(image.cols(), image.rows(), Bitmap.Config.ARGB_8888);
    Utils.matToBitmap(image, imageBitmap);
    BitmapHelper.showBitmap(this, imageBitmap, imageView);
