How to call Android contacts list?

Question

I'm making an Android app, and need to call the phone's contact list. I need to call the contacts list function, pick a contact, then return to my app with the contact's name. Here's the code I got on the internet, but it doesnt work.

import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.Contacts.People;
import android.view.View;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;

public class Contacts extends ListActivity {

    private ListAdapter mAdapter;
    public TextView pbContact;
    public static String PBCONTACT;
    public static final int ACTIVITY_EDIT=1;
    private static final int ACTIVITY_CREATE=0;

    // Called when the activity is first created. 
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        Cursor C = getContentResolver().query(People.CONTENT_URI, null, null, null, null);
        startManagingCursor(C);

        String[] columns = new String[] {People.NAME};
        int[] names = new int[] {R.id.row_entry};

        mAdapter = new SimpleCursorAdapter(this, R.layout.mycontacts, C, columns, names);
        setListAdapter(mAdapter);
    } // end onCreate()
    // Called when contact is pressed
    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);

        Cursor C = (Cursor) mAdapter.getItem(position);
        PBCONTACT = C.getString(C.getColumnIndex(People.NAME));

        // RHS 05/06
        //pbContact = (TextView) findViewById(R.id.myContact);
        //pbContact.setText(new StringBuilder().append("b"));

        Intent i = new Intent(this, NoteEdit.class);
        startActivityForResult(i, ACTIVITY_CREATE);
    }
}

    package com.testingContect;

    import android.app.Activity;
    import android.content.Intent;
    import android.database.Cursor;
    import android.net.Uri;
    import android.os.Bundle;
    import android.provider.ContactsContract;
    import android.provider.Contacts.People;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.Toast;

    public class testingContect extends Activity implements OnClickListener{
    /** Called when the activity is first created. */

    EditText ed;
    Button bt;
    int PICK_CONTACT;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        bt=(Button)findViewById(R.id.button1);
        ed =(EditText)findViewById(R.id.editText1);
        ed.setOnClickListener(this);
        bt.setOnClickListener(this);


    }

    @Override
    public void onClick(View v) {

        switch(v.getId())
        {
        case R.id.button1:

            break;
        case R.id.editText1:
             Intent intent = new Intent(Intent.ACTION_PICK);
              intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
              startActivityForResult(intent, PICK_CONTACT);


            break;

        }

    }
    public void onActivityResult(int requestCode, int resultCode, Intent intent) 
    {

      if (requestCode == PICK_CONTACT)
      {         
          Cursor cursor =  managedQuery(intent.getData(), null, null, null, null);
          cursor.moveToNext();
          String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
           String  name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME)); 

          Toast.makeText(this, "Contect LIST  =  "+name, Toast.LENGTH_LONG).show(); 
      }
    }//onActivityResult
}//class ends
