RecyclerView适配器

public class SongsAdapter extends RecyclerView.Adapter<SongsAdapter.MyViewHolder>{
    Context context;
    ArrayList<HashMap<String, String>> songList;

    public SongsAdapter(ArrayList<HashMap<String, String>> songList,Context context) {
        this.songList = songList;
        this.context=context;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item, parent, false);
        return new MyViewHolder(view,context);

    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {

        holder.textView.setText(songList.get(position).get("file_name"));
    }

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

    public class MyViewHolder extends RecyclerView.ViewHolder  implements View.OnClickListener {
        private TextView textView;
        Context context;

        public MyViewHolder(View itemView, Context context){
            super(itemView);
            this.context = context;
            textView=(TextView)itemView.findViewById(R.id.listitemtextview);

        }

        @Override
        public void onClick(View v) {
            int position=getAdapterPosition();
            Log.d(TAG, "onClick: ");
            Toast.makeText(context,"Hi",Toast.LENGTH_LONG).show();
        }
    }

}

点击recyclerview无效。我想点击recyclerview进入下一个活动。请帮忙。我尝试了一切,但没有任何作用。我经历了stackoverflow的所有相关主题的问题。我的CardView布局中没有任何onclick = true

根据android点击监听器你需要先用监听器注册然后你可以在onClick()中获取事件所以首先用clickeble对象注册监听器然后你可以在onClick()中获取事件或者你可以直接注册使用匿名类,如下面的方式

itemView.setOnClickListener(this)

itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });
