推荐答案

我使用了以下方法，并将捕获的位图图像传递给此方法。

I have used following method and passed my captured bitmap image to this method. And it will work.

public Bitmap getRoundedShape(Bitmap scaleBitmapImage) {
        int targetWidth = 125;
        int targetHeight = 125;

        Bitmap targetBitmap = Bitmap.createBitmap(targetWidth,
                targetHeight, Bitmap.Config.ARGB_8888);

        Canvas canvas = new Canvas(targetBitmap);
        Path path = new Path();
        path.addCircle(
                ((float) targetWidth - 1) / 2,
                ((float) targetHeight - 1) / 2,
                (Math.min(((float) targetWidth), ((float) targetHeight)) / 2),
                Path.Direction.CCW);

        canvas.clipPath(path);
        Bitmap sourceBitmap = scaleBitmapImage;
        canvas.drawBitmap(
                sourceBitmap,
                new Rect(0, 0, sourceBitmap.getWidth(), sourceBitmap
                        .getHeight()), new Rect(0, 0, targetWidth,
                        targetHeight), p);
        return targetBitmap;
    }

输出如下：-

And the output is as follows:-
