クリックコード

私はクリックするたびに、それは次のようにする必要がありますどのように私は私のプロジェクトでは、このコードを実装する必要がありますclidオプションのPDFを開きます

誰でもこれを手伝うことができます。

これを追加するたびにエラーが発生します。あなたのカスタムビューホルダーに

@Override 
    public void onBindChildViewHolder(IssueViewHolder issueViewHolder, int position, Object childListItem) { 
     Issue issue = (Issue) childListItem; 
     issueViewHolder.bind(issue); 

     issueViewHolder.itemView.setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View view) { 
         //your code 
        } 
       }); 
    }

アダプタクラスでインターフェイスを定義し

public interface onItemClickListener { 
     void onItemClicked(View view, int position); 
    } 

public void setOnItemClickListener(onItemClickListener listener) { 
     this.onItemClickListener = listener; 
    }

View.OnClickListnerを実装し、必要なビューのリスナーをクリックして設定します。

アダプタオブジェクトで今すぐ 
public static class CustomViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

CustomViewHolder(View itemView){ 
super(itemView); 
yourview.setOnClickListener(this); 
} 
@Override 
     public void onClick(View view) { 
      onItemClickListener.onItemClicked(view, getAdapterPosition()); 
     } 
}

だけsetOnItemClickListenerを追加して、あなたは、ビューのIDを使用して、クリックイベントを分岐することができます。

yourAdapter.setOnItemClickListener(new YourAdapter.onItemClickListener() { 
      @Override 
      public void onItemClicked(View view, int position) { 
    // view.getId() 
});

各オプションを別々に開きますか？ –

+0

clickイベントを必要とする各ビューでsetOnClickListenerを設定します。これにより、それぞれのidとpositionを持つonItemClickListnerを取得できるようになります –
