Android: onClick image make invisible Textview

Question

I've done an Activity with an image in full screen and below a textview with its description. What I want is to make invisible textview when I click on the image. I have placed a Toast and there goes the code, but is not invisible. What can be the error? thanks

    public Object instantiateItem(ViewGroup view, int position) {

        View imageLayout = inflater.inflate(R.layout.ampliar_imagen, view, false);
        assert imageLayout != null;

        imageView = (TouchImageView) imageLayout.findViewById(R.id.imagenFullScreen);

        info = (TextView) imageLayout.findViewById(R.id.textoInfoImagen);

                    final ProgressBar spinner = (ProgressBar) imageLayout.findViewById(R.id.cargandoFoto);
        imageView.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                Toast.makeText(ImagePagerActivity.this, "CLICK", Toast.LENGTH_SHORT).show();
                info.setVisibility(View.GONE);
            }

        });

        imageLoader.displayImage(images[position], imageView, options, new SimpleImageLoadingListener() {

            @Override
            public void onLoadingStarted(String imageUri, View view) {
                spinner.setVisibility(View.VISIBLE);
            }

            @Override
            public void onLoadingFailed(String imageUri, View view, FailReason failReason) {

                Toast.makeText(ImagePagerActivity.this, "Error al cargar la imagen", Toast.LENGTH_SHORT).show();

                spinner.setVisibility(View.GONE);
            }

            @Override
            public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
                spinner.setVisibility(View.GONE);
            }
        });

        view.addView(imageLayout, 0);
        return imageLayout;
    }

You can define the textview in oclick event like this

  imageView.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

 TextView info = (TextView) imageLayout.findViewById(R.id.textoInfoImagen);
 info.setVisibility(View.GONE);//or you can invisible,

 }

        });
