我有一个圆形图像,我想为圆形图像应用动画,这样它应该慢慢转换成更大尺寸的圆角图像。我尝试将圆形图像转换为圆角,但无法编写类似动画的效果。

这使我将图像转换为圆角矩形,但我想要这种性能的动画。我的动画应该慢慢地将我的圆形图像转换为带圆角的矩形,并且尺寸也会增加

public  Bitmap getRoundedRectBitmap(Bitmap bitmap, int pixels)
    {
        result = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
        canvas = new Canvas(result);

        color = 0xff424242;
        paint = new Paint();
        rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
        rectF = new RectF(rect);
        roundPx = pixels;

        paint.setAntiAlias(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(color);
        canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(bitmap, rect, rect, paint);

        return result;
    }
