I have copied and executed almost the same code and it works:

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Cursor cur = getContacts();

        ListView lv = getListView();

       String[] fields = new String[] {ContactsContract.Data.DISPLAY_NAME};

       SimpleCursorAdapter adapter = 
                new SimpleCursorAdapter(this, 
                                        R.layout.main,
                                        cur,
                                        fields,
                                        new int[] {R.id.txtbox});
          lv.setAdapter(adapter);         
    }    

    private Cursor getContacts() {  
        // Run query     
        Uri uri = ContactsContract.Contacts.CONTENT_URI;

        String[] projection = 
                new String[]{ ContactsContract.Contacts._ID,
                              ContactsContract.Contacts.DISPLAY_NAME }; 
            String selection = null;
            String[] selectionArgs = null;  
            String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + 
                " COLLATE LOCALIZED ASC";  
            return managedQuery(uri, projection, selection, selectionArgs, sortOrder);
    }

Please check if you have done anything wrong in the textview implementation?

First I would just narrow the problem.

1) Check if you have permissions for reading contacts

<uses-permission android:name="android.permission.READ_CONTACTS"/>

2) Check if cursor have any results

cur.getCount()
