java-在ViewHolder中未输入OnClickListener

我有一个回收站视图,显示用户在我的应用程序中发布的所有帖子.我希望用户能够单击其中一个帖子,并带到一个新片段,在该片段中,他们只能看到他们选择的帖子.

当我运行代码并单击其中一篇文章时,甚至不会触发OnCLickListener.

我曾尝试在公共无效的OnClick上添加断点,但从未触发过断点.我尝试将OnClick添加到onBindViewHolder,但我知道这不是一个好主意.

public class PostAdapter extends RecyclerView.Adapter<PostAdapter.PostViewHolder> {
public List<Post> postList;
private Context context;
private static OnItemClickListener onItemClickListener;

public PostAdapter(){
}

public interface OnItemClickListener{
    void onItemClick(View v, int position);
}

public void updateList(List<Post> list){
    postList = list;
    notifyDataSetChanged();
}

public static class PostViewHolder extends RecyclerView.ViewHolder{
    TextView postName, postUsername, postDate, postTime, postContent, postId;

    PostViewHolder(View v) {
        super(v);
        this.postName = (TextView) itemView.findViewById(R.id.name);
        this.postUsername = (TextView) itemView.findViewById(R.id.username);
        this.postDate = (TextView) itemView.findViewById(R.id.date);
        this.postTime = (TextView) itemView.findViewById(R.id.time);
        this.postContent = (TextView) itemView.findViewById(R.id.content);
        this.postId = (TextView) itemView.findViewById(R.id.postId);
        v.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int position = PostViewHolder.super.getAdapterPosition();
                onItemClickListener.onItemClick(v, position);
                System.out.println("doesn't even make it here");

            }
        });
    }
}

public PostAdapter(List<Post> postList, Context context){
    this.postList = postList;
    this.context = context;
}

@Override
public PostAdapter.PostViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
    View view = LayoutInflater.from(context).inflate(R.layout.all_posts_layout, parent, false);
    return new PostAdapter.PostViewHolder(view);
}

@Override
public void onBindViewHolder(PostViewHolder holder, int position){
    Post post = postList.get(position);
    holder.postUsername.setText(String.valueOf(post.getUsername()));
    holder.postName.setText(String.valueOf(post.getName()));
    holder.postDate.setText(String.valueOf(post.getDate()));
    holder.postTime.setText(String.valueOf(post.getTime()));
}

@Override
public int getItemCount(){
    return this.postList.size();
}

任何帮助将不胜感激！

解决方法:

好像您的ScrollView消耗了click事件.尝试将其删除或替换为NestedScrollView
