如何打开多个活动而不创建新的多个活动

Question

我想从列表视图创建多个活动，但是为此，我需要创建n个新活动。假设我在列表视图中有20个项目，所以我无法创建20个新活动。因此，请帮助我打开这20个活动而不创建新的20个活动。

package com.example.grepmylinux;

import android.content.Context;
import android.content.Intent;
import android.support.v7.widget.RecyclerView;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.RelativeLayout;
import android.widget.TextView;
import android.widget.Toast;

import java.util.ArrayList;

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

    private static final String TAG = "RecyclerViewAdapter";

    private ArrayList<String> mTopicsNames = new ArrayList<>();
    private Context mcontext;

    public RecyclerViewAdapter(Context mcontext, ArrayList<String> mTopicsNames) {
        this.mTopicsNames = mTopicsNames;
        this.mcontext = mcontext;
    }


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

    @Override
    public void onBindViewHolder(ViewHolder holder, final int position) {
        Log.d(TAG, "onBindViewHolder: called.");

        holder.topics_name.setText(mTopicsNames.get(position));

        holder.parent_layout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "onClick: " + mTopicsNames.get(position));

                Toast.makeText(mcontext, mTopicsNames.get(position), Toast.LENGTH_SHORT).show();

                Intent intent = new Intent(mcontext, topics.class);
                intent.putExtra("topics_name", mTopicsNames.get(position));
                mcontext.startActivity(intent);
            }
        });
    }

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

    public class ViewHolder extends RecyclerView.ViewHolder {

        TextView topics_name;
        RelativeLayout parent_layout;

        public ViewHolder(View itemView) {
            super(itemView);
            topics_name = itemView.findViewById(R.id.topics_name);
            parent_layout = itemView.findViewById(R.id.parent_layout);

        }
    }
}

请检查上面的RecyclerView代码。我尝试过，但是当我单击第一个列表项时，它将把我重定向到同一页面，即循环。
