RecyclerView single click not working but works when click twice

Question

I am trying to receive clicks on RecyclerView items for which I am using callback mechanism. I have created OnItemClickListener Interface and inside custom Adapter, I have written logic for detecting click with the help of View.OnClickListener. But I am getting a callback in myActivity after double clicking any item in the list. Not getting any clue what's happening here!

Code inside Activity:

mAdapter = new AppAdapter(this, mAppList, new OnItemClickListener() {         @Override         public void onItemClick(View v, int position) {              Toast.makeText(SelectAppActivity.this, "Hello", Toast.LENGTH_SHORT).show();         } });  recyclerview.setAdapter(mAdapter); 

Code For Interface:

public interface OnItemClickListener {      void onItemClick(View v, int position); } 

Code for Custom Adapter:

public class AppAdapter extends RecyclerView.Adapter<AppAdapter.ItemViewHolder> {      List<App> mAppList;     List<App> mFilterAppList;     Activity context;     OnItemClickListener onItemClickListener;      public AppAdapter(Activity context, List<App> appList, OnItemClickListener onItemClickListener) {         super();         this.context = context;         this.mAppList = appList;         this.mFilterAppList = appList;         this.onItemClickListener = onItemClickListener;     }      @Override     public ItemViewHolder onCreateViewHolder(final ViewGroup parent, int viewType) {         final View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_app_list, parent, false);          final ItemViewHolder viewHolder = new ItemViewHolder(view);          view.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 onItemClickListener.onItemClick(v,4);             }         });         return viewHolder;     }      @Override     public void onAttachedToRecyclerView(RecyclerView recyclerView) {         super.onAttachedToRecyclerView(recyclerView);     }      @Override     public void onBindViewHolder(ItemViewHolder holder, int position) {         final App app = mAppList.get(position);         holder.name.setText(app.getmName());         holder.icon.setImageDrawable(app.getmAppIcon());     }      @Override     public int getItemCount() {         return mAppList.size();     }      public void setFilter(List<App> appList) {         mAppList = new ArrayList<>();         mAppList.addAll(appList);         notifyDataSetChanged();     }      public static class ItemViewHolder extends RecyclerView.ViewHolder {          public TextView name;         public ImageView icon;          public ItemViewHolder(View view) {             super(view);             name = (TextView) itemView.findViewById(R.id.app_name);             icon = (ImageView) itemView.findViewById(R.id.app_icon);         }     } }

The issue was related to android:focusable="true" in my layout, as I removed this it was working fine,all suggested answers are also working fine.Thanks, all.
