如何在Piccaso上获取位图，然后将其更改为OpenCV Mat

Question

主要问题是如何从毕加索获取位图，因为我想使用Utils.bitmapToMat()将位图更改为Mat OpenCV。我已经搜索并找到下面的代码

代码

    if(requestCode == GET_IMAGE_FROM_GALERY && resultCode == Activity.RESULT_OK){
        Uri selectedImageURI = data.getData();

        Picasso.get().load(selectedImageURI).into(new Target() {
            @Override
            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                bitmapimage = bitmap;
                images.setImageBitmap(bitmapimage);                                                          
            }

            @Override
            public void onBitmapFailed(Exception e, Drawable errorDrawable) {
               e.printStackTrace();
            }

            @Override
            public void onPrepareLoad(Drawable placeHolderDrawable) {

            }
        });

    }

，但是图像永远不会显示在ImageView上。因此，我很高兴地从来没有从毕加索那里得到位图，我该怎么办？因为我需要Bitmap变量才能使用opencv获取Mat。

这是在Log Cat上

错误
