Android:onClick 图像使 Textview 不可见

Question

我已经完成了一个 Activity ，其中包含全屏图像和 TextView 下方及其描述。我想要的是在单击图像时使 TextView 不可见。我放了一个 toast ，代码就在那里，但不是不可见的。可能是什么错误？谢谢

    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;
    }

我建议您将 imageLayout 设置为 imageView 的标签，并在 ImageView 的 onClick 中从标签布局获取您的 textview，然后将其可见性设置为消失或不可见。试试这个。

 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);

     }
