Java 回收者查看图像不是'；t单击以打开新页面

我试图让RecyclerView中的每个图像都可以点击打开照片，以及照片的标题和描述，但所有这些信息都来自Flickr，我添加了我认为合适的代码，但它似乎不起作用，因为没有图像可以点击，非常感谢您提供有关如何解决此问题的任何指导

在details类中使用一个简单的findByViewId（）方法就足够了，还是我缺少了更多的方法？就像我说的，任何帮助都是感激的

谢谢大家!

ImageListAdapter类

    View v = LayoutInflater.from(context).inflate(R.layout.cell_image_card, parent, false);

    ImageListAdapter.ViewHolder vh = new ImageListAdapter.ViewHolder(v);
    return vh;
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    ImageInfo imageInfo = imageList.get(position);


    holder.imageTitle.setText(imageInfo.title);
    holder.mainImage.setImageUrl(imageInfo.url_m, 
NetworkMgr.getInstance(context).imageLoader);
 //   holder.mainImage.setImageResource(imageInfo.imageResource);

}

您只是忘记在mainImage视图上设置onClick侦听器

步骤1：在mainImage上设置单击侦听器

   public ViewHolder(View itemView) {
        super(itemView);
        final Context mContext = itemView.getContext();
        final int position = getAdapterPosition();
        imageTitle = (TextView) itemView.findViewById(R.id.imageTitle);
        mainImage = (NetworkImageView) 
        itemView.findViewById(R.id.mainImage);
        mainImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
          Intent intent = new Intent(mContext, DetailsActivity.class);
          intent.putExtra("PHOTO_POSITION", position);
          mContext.startActivity(intent);
          }
       });
    }

第二步：在细节活动中获得这样的职位

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_details);
    Intent intent = getIntent();
    int position = intent.getIntExtra("PHOTO_POSITION", 0);
    ImageInfo imageInfo = NetworkMgr.getInstance(this).imageList.get(position);
    //use image info to get the image and title details.

}

添加imageTitle=（TextView）itemView.findViewById（R.id.imageTitle）；mainImage=（NetworkImageView）@StringForever我会在ViewHolder（View itemView）的DetailsActivity？中添加此选项吗

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_details);
    Intent intent = getIntent();
    int position = intent.getIntExtra("PHOTO_POSITION", 0);
    ImageInfo imageInfo = NetworkMgr.getInstance(this).imageList.get(position);
    //use image info to get the image and title details.

}
