Implementieren Sie den ItemClickListener in einem recyclerView

Question

Ich habe es seit 2 Tagen versucht, implementieren Sie den ItemClickListener in einem RecyclerView und es funktioniert nicht. bitte helfen

Wie kann ich den ItemClickListener in dieser .class implementieren?

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

Sie können diesen Code verwenden

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

In RecyclerView, gibt es keine direkte Unterstützung wie onItemClickListener jedoch müssen Sie auf Ihrem Adapter Klasse wie diese, die Sie kann helfen ist.

public class ViewHolder extends RecyclerView.ViewHolder{ 
    View view; 

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

und Sie haben auf onBindViewHolder Onclick Methode Feuer,

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()); 
    } 
}); 

Ich denke, das ist die Art und Weise der wir den Blick auf recyclerview klicken.

Ich möchte @Dharma Kshetri und @Rahul Pareta für ihre Antworten danken. Danke Dies ist die Lösung:

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

    public Platos_Adapter(List<Estadisticas> estadisticas, Context context) { 
     super(); 
     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; 
    } 

    public void onBindViewHolder(ViewHolder holder, final int position) { 
     holder.root.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 

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

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

      private int getAdapterPosition() { 
       return 0; 
      } 
     }); 
     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); 
      textViewCategoria = (TextView) itemView.findViewById(R.id.tv_ek_visi); 
     } 
    } 
}
