Android: onClick image make invisible Textview

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;
    }

XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/negro" >

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <imagenes.TouchImageView
        android:id="@+id/imagenFullScreen"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:adjustViewBounds="true" />

    <ProgressBar
        android:id="@+id/cargandoFoto"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:visibility="gone" />
</FrameLayout>

<TextView
    android:id="@+id/textoInfoImagen"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:background="@color/grisTransparente"
    android:gravity="center_horizontal"
    android:paddingBottom="3dp"
    android:paddingTop="3dp"
    android:text="AAAA"
    android:textColor="@color/blanco"
    android:textSize="13sp" />

</RelativeLayout>

I will suggest you to set your imageLayout as tag of imageView and in onClick of image view get your textview from tag layout and then set its visibility gone or invisible. try this.

 imageView = (TouchImageView) imageLayout.findViewById(R.id.imagenFullScreen);
 info = (TextView) imageLayout.findViewById(R.id.textoInfoImagen);  
 imageView.setTag(info);
 imageView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

         TextView tv = (TextView)v.getTag();
         tv.setVisibility(View.GONE);

     }

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,

 }

        });

in your xml set , 

      android:visibility="true"
      //in textview

and in your activity,

              info.setVisibility(View.INVISIBLE);

Instead of this

info.setVisibility(View.GONE);

use this:-

info.setVisibility(View.INVISIBLE);

Set Visibility to your textview in xml:-

   <TextView
        android:id="@+id/textoInfoImagen"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:background="@color/grisTransparente"
        android:gravity="center_horizontal"
        android:paddingBottom="3dp"
        android:paddingTop="3dp"
        android:text=""
        **android:visibility="visible"**
        android:textColor="@color/blanco"
        android:textSize="13sp" />
