How to open different webpage from same activity from the listview which has different items?

You can see I have three cases on the MainActivty.java which is pointing on the same activity Ekantipur.java but in Ekantipur.java I have only one link. So when you click any of the three listview it will open the same links. So I want to open different links when you click on different listview items when different position in listview is clicked.

I donot want to make different activity for that. This is just with three cases but I have around 20 links and I donot want to make 20 acitvity with same source code and only different weblinks.

MainActivityParent.java

package com.example.listviewselfmade;

import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class MainActivityParent extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // storing string resources into Array
        String[] adobe_products = getResources().getStringArray(R.array.newsparent);

        // Binding Array to ListAdapter
        this.setListAdapter(new ArrayAdapter<String>(this, R.layout.main,
                R.id.label, adobe_products));

        ListView lv = getListView();

        // listening to single list item on click
        lv.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {

                switch (position) {
                case 0:
                    startActivity(new Intent("com.example.listviewselfmade.MAINCHILD"));

                    break;
                case 1:
                    startActivity(new Intent("com.example.listviewselfmade.MAINCHILD"));

                    break;
                case 2:
                    startActivity(new Intent("com.example.listviewselfmade.MAINCHILD"));

                    break;


                }

            }
        });
    }
}

MainActivity.java

package com.example.listviewselfmade;

import android.app.ListActivity;
import android.content.Intent;

        // storing string resources into Array
        String[] adobe_products = getResources().getStringArray(R.array.news);

        // Binding Array to ListAdapter
        this.setListAdapter(new ArrayAdapter<String>(this, R.layout.main,
                R.id.label, adobe_products));

        ListView lv = getListView();

        // listening to single list item on click
        lv.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {

                switch (position) {
                case 0:
                    startActivity(new Intent("com.example.listviewselfmade.EKANTIPUR"));
                    break;
                case 1:
                    startActivity(new Intent("com.example.listviewselfmade.EKANTIPUR"));
                    break;

                    break;

                }

            }
        });
    }
}

        // Adds Progress bar Support
        this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
        super.onCreate(savedInstanceState);

        setContentView(R.layout.webviewxml);

        // Makes Progress bar Visible
        getWindow().setFeatureInt(Window.FEATURE_PROGRESS,
                Window.PROGRESS_VISIBILITY_ON);

        WebView mainWebView = (WebView) findViewById(R.id.webview);

        mainWebView.setWebChromeClient(new WebChromeClient() {
            public void onProgressChanged(WebView view, int progress) {
                // Make the bar disappear after URL is loaded, and changes
                // string to Loading...
                MyActivity.setTitle("Loading...");
                MyActivity.setProgress(progress * 100); // Make the bar
                                                        // disappear after URL
                                                        // is loaded

                // Return the app name after finish loading
                if (progress == 100)
                    MyActivity.setTitle(R.string.app_name);
            }
        });

        // enable javascript
        WebSettings webSettings = mainWebView.getSettings();

public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
    Intent intent = new Intent(MainActivityParent.this, MainActivity.class);
    intent.putExtra("product", adobe_products[position]);
    startActivity(intent);
}

Then in the onCreate of the MainActivity

String product = getIntent().getStringExtra("product");

And whatever you need to do with that. Pretty much the same with passing data from the second to the third activity, just use the corresponding classes and data.

public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
    Intent intent = new Intent(MainActivity.this, Ekantipur.class);
    intent.putExtra("url", adobe_products[position]);
    startActivity(intent);
}

And in Ekantipur

mainWebView.loadUrl(getIntent().getStringExtra("url"));
