は、recyclerView内のItemClickListenerを実装しています

Question

私は2日間それを試してきました。そして、recyclerViewにItemClickListenerを実装しても機能しません。助けてください

このクラスにItemClickListenerを実装するにはどうすればいいですか？

public class Platos_Adapter extends 
    RecyclerView.Adapter<Platos_Adapter.ViewHolder> { 

      private ImageLoader imageLoader; 
      private Context context; 

      List<Estadisticas> estadisticas; 

      public Platos_Adapter(List<Estadisticas> comida,Context context){ 
       super(); 
       //Getting all the comida 
       this.estadisticas = estadisticas; 
       this.context = context; 
      } 

      @Override 
      public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
       View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.platos_row, 
    parent, false); 
       ViewHolder viewHolder = new ViewHolder(v); 
       return viewHolder; 
      } 

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

       holder.setOnClickListener((View.OnClickListener) this); 

       Estadisticas superHero = estadisticas.get(position); 

       imageLoader = DecoracionLineaDivisoria.CustomVolleyRequest.getInstance(context).getImageLoader(); 

       imageLoader.get(superHero.getEscudo_Local(), ImageLoader.getImageListener(holder.escudo_local, 
    R.mipmap.ic_launcher, android.R.drawable.ic_dialog_alert)); 

       holder.escudo_local.setImageUrl(superHero.getEscudo_Local(), 
    imageLoader); 
       holder.textViewEquipo_Local.setText(superHero.getEquipo_Local()); 
      } 

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

      class ViewHolder extends RecyclerView.ViewHolder{ 
       public NetworkImageView escudo_local; 
       public TextView textViewEquipo_Local; 

       public ViewHolder(View itemView) { 
        super(itemView); 

        escudo_local = (NetworkImageView) itemView.findViewById(R.id.tv_esc_local); 
        textViewEquipo_Local= (TextView) itemView.findViewById(R.id.tv_ek_local); 
     ;  } 


       public void setOnItemClickListener(ViewHolder.OnItemClickListener 
    onClickListener) { 

        public void onClick(View view) { 

         Toast.makeText(Platos_Adapter.this, "clicked" ,Toast.LENGTH_SHORT).show(); 

         Estadisticas comida = estadisticas.get(getAdapterPosition()); 
        } 
       } 
      } 
     } 

Answer 1

あなたはこのコードにRecyclerViewで

public class Platos_Adapter extends RecyclerView.Adapter { 
private ImageLoader imageLoader; 
private Context context; 
List<Estadisticas> estadisticas; 

public Platos_Adapter(List<Estadisticas> comida,Context context){ 
    super(); 
    //Getting all the comida 
    this.estadisticas = estadisticas; 
    this.context = context; 
} 

@Override 
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.platos_row, parent, false); 
    ViewHolder viewHolder = new ViewHolder(v); 
    return viewHolder; 
} 

@Override 
public void onBindViewHolder(ViewHolder holder, int position) { 
    holder.root.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Toast.makeText(context, "clicked" ,Toast.LENGTH_SHORT).show(); 
      Estadisticas comida = estadisticas.get(getAdapterPosition()); 
     } 
    }); 
    Estadisticas superHero = estadisticas.get(position); 
    imageLoader = DecoracionLineaDivisoria.CustomVolleyRequest.getInstance(context).getImageLoader(); 
    imageLoader.get(superHero.getEscudo_Local(), ImageLoader.getImageListener(holder.escudo_local, R.mipmap.ic_launcher, android.R.drawable.ic_dialog_alert)); 
    holder.escudo_local.setImageUrl(superHero.getEscudo_Local(), imageLoader); 
    holder.textViewEquipo_Local.setText(superHero.getEquipo_Local()); 
} 

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

class ViewHolder extends RecyclerView.ViewHolder{ 
    public NetworkImageView escudo_local; 
    public TextView textViewEquipo_Local; 
    public View root; 

    public ViewHolder(View itemView) { 
     super(itemView); 
     root=itemView; 
     escudo_local = (NetworkImageView) itemView.findViewById(R.id.tv_esc_local); 
     textViewEquipo_Local= (TextView) itemView.findViewById(R.id.tv_ek_local); 
    } 
} 

Answer 2

を使用することができ、ちょうどonItemClickListenerなどの直接的なサポートはありません、しかし、あなたはあなたを助けることがあるだけで、このようなあなたのアダプタクラス、上に持っています。私が思う

public class ViewHolder extends RecyclerView.ViewHolder{ 
    View view; 

    public ViewHolder(View itemView) { 
     super(itemView); 
     view=itemView; 
} 
} 

、あなたはonclickのonBindViewHolder、

holder.view.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
     Toast.makeText(Platos_Adapter.this, "clicked" ,Toast.LENGTH_SHORT).show(); 

     Estadisticas comida = estadisticas.get(getAdapterPosition()); 
    } 
}); 

の方法を発射する必要があり、これはrecyclerviewのビューをクリックすることができ、私たちの方法です。

       Toast.makeText(context, estadisticas.get(position).getEquipo_Local(), Toast.LENGTH_SHORT).show(); 

       Estadisticas estadisticas1 = estadisticas.get(getAdapterPosition());
