`import android.content.Context; import android.content.Intent; import android.net.Uri; import android.support.v7.widget.RecyclerView; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.LinearLayout; import android.widget.TextView;

import java.util.ArrayList;

import ca.barrenechea.widget.recyclerview.decoration.StickyHeaderAdapter;

  private Context context; private LayoutInflater mInflater; private ArrayList items ; private Integer[] mHeaderPositions = {0, 3, 8, 12, 31, 32, 53, 54,55,69,71,82}; public StickyNumbersHeader(Context context) { mInflater = LayoutInflater.from(context); this.context = context; }

  public void insertItems(ArrayList phoneNumbersArrayList){ this.items = phoneNumbersArrayList; } @Override public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { final View view = mInflater.inflate(R.layout.phone_item, parent, false);

  return new ViewHolder(view);

  }

  @Override public void onBindViewHolder(ViewHolder holder, final int position) { holder.number.setText(items.get(position).getNumber()); holder.title.setText(items.get(position).getTitle()); holder.itemContainer.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { openDial(items.get(position).getNumber()); } }); }

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

  @Override public long getHeaderId(int position) { if(position<=2){ return mHeaderPositions[0]; }else if(position<=7){ return mHeaderPositions[1]; }else if(position<=11){ return mHeaderPositions[2]; }else if(position<=30){ return mHeaderPositions[3]; }else if(position==31){ return mHeaderPositions[4]; }else if(position<=52){ return mHeaderPositions[5]; }else if(position==53){ return mHeaderPositions[6]; }else if(position==54){ return mHeaderPositions[7]; }else if(position<=68){ return mHeaderPositions[8]; }else if(position<=70){ return mHeaderPositions[9]; }else if(position<=81){ return mHeaderPositions[10]; }else{ return mHeaderPositions[11]; } }

  @Override public HeaderHolder onCreateHeaderViewHolder(ViewGroup parent) { final View view = mInflater.inflate(R.layout.header_phone, parent, false); return new HeaderHolder(view); }

  @Override public void onBindHeaderViewHolder(HeaderHolder viewholder, int position) { viewholder.header.setText(items.get(position).getCategory()); }

  static class HeaderHolder extends RecyclerView.ViewHolder { public TextView header;

  }

  }

    number = (TextView) itemView.findViewById(R.id.phone_number);
    itemContainer = (LinearLayout) itemView.findViewById(R.id.item_container);
  }

  } public void openDial(String phoneNumber){ Intent intent = new Intent(Intent.ACTION_DIAL); intent.setData(Uri.parse("tel:" + phoneNumber)); this.context.startActivity(intent); }
