RecyclerView のアイテムの中のある部分のクリック

まずは, 入れ子なしでばらして書かせたほうがいいような気がするのです.

java - Why doesn't RecyclerView have onItemClickListener()? And how RecyclerView is different from Listview? - Stack Overflow


public static class MyViewHolder extends RecyclerView.ViewHolder {

  public TextView text;
  public ImageView image;
  public OnClickPartsListener listener;

  public MyViewHolder(View itemView, OnClickPartsListener listener) {
    super(itemView);

    this.listener = listener;
    text = (TextView) itemView.findViewById(R.id.text);
    image = (ImageView) itemView.findViewById(R.id.image);

    text.setOnClickListener(new View.OnClickListener {
      listener.onClickText("Text Clicked!!");
    });

    image.setOnClickListener(new View.OnClickListener {
      listener.onClickImage("Image Clicked!!");
    });

  }

  public interface OnClickPartsListener {
    void onClickText(String message);
    void onClickImage(String message);
  }

}


public class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {

  private MyViewHolder.OnClickPartsListener listener;

  public MyAdapter(MyViewHolder.OnClickPartsListener listener) {
    this.listener = listener;
  }

  @Override
  public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    //..	 
    return new MyViewHolder(view, listener);
  }

}


public class MyActivity extends AppCompatActivity {  
  
  @Override  
  protected void onCreate(Bundle savedInstanceState) {  

    MyViewHolder.OnClickPartsListener listener =
      new MyViewHolder.OnClickPartsListener() {
  
        public void onClickText(String message) {
          Toast.makeText(this, message, LENGTH_SHORT).show();  
        }

        public void onClickImage(String message) {
          Toast.makeText(this, message, LENGTH_SHORT).show();  
        }

      };

    recyclerView = (RecyclerView) findViewById(R.id.recycler_view);  
    adapter = new MyAdapter(listener) {  
    recyclerView.setAdapter(adapter);  

  }

}

めんどくさいので,


public class MyAdapter extends RecyclerView.Adapter<MyViewHolder> {

  private final PublishSubject<String> onClickSubject = PublishSubject.create();

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

    final Item item = items.get(position);

    holder.itemView.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        onClickSubject.onNext(item);
      }
    });
  }

  public Observable<String> getPositionClicks(){
    return onClickSubject.asObservable();
  }

}

または, イベントバス..
