Как загрузить изображение в Android Studio с возможностью масштабирования его на телефоне?

public static Bitmap getScaledBitmap(String path, int destWidth, int destHeight){

        //read in the dimensions of the image on disk
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(path, options);

        float srcWidth = options.outWidth;
        float srcHeight = options.outHeight;

        //figure out how much to scale down by
        int inSampleSize = 1;
        if(srcHeight > destHeight || srcWidth > destWidth){
            if(srcWidth > srcHeight)
                inSampleSize = Math.round(srcHeight / destHeight);
            else
                inSampleSize = Math.round(srcWidth / destWidth);
        }

        options = new BitmapFactory.Options();
        options.inSampleSize = inSampleSize;

        //read in and create final bitmap
        return BitmapFactory.decodeFile(path, options);
    }
