You can use this source code as a reference:

import android.app.Activity; 
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.AsyncTask;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class Test1Activity extends Activity  {

    private static final int PICK_CONTACT_REQUEST = 1;

    private static final int PICK_CONTACT = 0;

    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button pickContact = (Button) findViewById(R.id.button1);

        pickContact.setOnClickListener(new OnClickListener() 
        {
            public void onClick(View v) {

                Intent i = new Intent(Intent.ACTION_INSERT_OR_EDIT);
                i.setType(ContactsContract.Contacts.CONTENT_ITEM_TYPE);   

                startActivity(i);
            }
        });

    }
