Apps How to put array populated by other activity to arraylist

[fighter123]

I am developing some application for android and i have problem.

I push data with button click from another activity with intent to string of first activity, and i put from that string these data to listview by a adapter, and it is all ok, i mean i see on listview that data, but when i want to add new item in listview by click of button of second activity, i mean do again same thing, there is a problem: that data i push by a second button click replaces first button click data, and i want to add that data under first data in another listview row?

here is code of activity where is a listview:

package com.example.kupi;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;

import android.R.array;
import android.app.Activity;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import android.widget.Toast;

public class popis_kupaca extends Activity {
public String ImeKupca;
public String PrezimeKupca;
public String OIBKupca;
public String AdresaKupca;

int i = 0;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.popis_kupaca);

ListView listView1 = (ListView) findViewById(R.id.listViewpopiskupaca);
listView1.setClickable(true);

ImeKupca = " ";
PrezimeKupca = " ";
OIBKupca = " ";
AdresaKupca = " ";

Intent intent = getIntent();
String[] values = intent.getStringArrayExtra("string-array");
String[] items = {ImeKupca + " " + PrezimeKupca + " " + OIBKupca + " " + AdresaKupca };

List<String> list = new ArrayList<String>();
ArrayList<String> arrayList = new ArrayList<String>(list);

if(values == null)
{
values = items;
}
else
{
ImeKupca = values[0];
PrezimeKupca = values[1];
OIBKupca = values[2];
AdresaKupca = values[3];

//items = new String[]{values[0] + " " + values[1] + " " + values[2] + " " + values[3] };
//items = values[0] + " " + values[1] + " " + values[2] + " " + values[3];
items = new String[]{values[0] + " " + values[1] + " " + values[2] + " " + values[3], "danas"};

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, items);
listView1.setAdapter(adapter);
}

//Dodaj Botun
Button pritisni4 = (Button) findViewById(R.id.dodaj1);
pritisni4.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), unos_kupca.class);
startActivityForResult(myIntent, 0);
i++;
}
});

//Odustani Botun
Button pritisni5 = (Button) findViewById(R.id.odustani1);
pritisni5.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), MainActivity.class);
startActivityForResult(myIntent, 0);
}
});
}
}
