Get me a list of contacts so I can choose

I want to get a list of contacts from the app and let them choose, but I googled and found a source. But it doesn't work properly.

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);
    }
}

What I want is to select a contact from the contact list and click OK to get the name of the contact. How shall I do it?

I don't know exactly what I'm trying to do in that example code, but from what I understand, Once <uses-permission android:name="android.permission.READ_CONTACTS"/> Register the permission in the manifest file.

Then, call the contact picker where you can select a contact. Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

startActivityForResult(intent, PICK_CONTACT); Invoke an activity that receives results by doing the . PICK_CONTACT is an example and you can specify any constant.

And in the activity of calling the content picker,

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
  super.onActivityResult(reqCode, resultCode, data);

  switch (reqCode) {
    case (PICK_CONTACT) :
      if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  getContentResolver().query(contactData, null, null, null, null);
        if (c.moveToFirst()) {
          String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
          // Receive the name of the TODO contact and process it as desired. 
        }
      }
      break;
  }
}

Override the onActivityResult method that receives and processes the results.
