As a complement to Balaji.K's answer, you don't need the String[] array. You can attach an ArrayList to a ListView by using an ArrayAdapter directly:

private ArrayList<String> arrayList = Arrays.asList("android_metadata", "test1", "test5", "test4", /*...*/ "test21", "test12");

ListView lv = (ListView) findViewById(R.id.list_view);
lv.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, arrayList));

try this code 

import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class Start extends Activity {

private String[] lv_arr = {};

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);


    // Get a handle to the list view
    ListView lv = (ListView) findViewById(R.id.ListView01);

    // Convert ArrayList to array
    lv_arr = (String[]) arrayList.toArray();
    lv.setAdapter(new ArrayAdapter<String>(Start.this,
            android.R.layout.simple_list_item_1, lv_arr));

}

This is the example

ArrayList yourlist = new ArrayList();

ArrayAdapter adapter = new ArrayAdapter<String>(context,android.R.layout.simple_list_item_1, yourlist);
yourlistview.setAdapter(adapter);
