如何从列表视图中的onItemClick()获取的列表项的联系人Uri中检索数据?

我该怎么做 从列表视图中的uri获取联系人详细信息 ? . 我已经从列表视图中获取了所选联系人的联系人uri。下面的代码片段是我尝试过的,但没有成功。更令人惊讶的是 日志记录语句甚至不执行!

@Override
public void onItemClick(
    AdapterView<?> parent, View item, int position, long rowID) {
    // Get the Cursor
    Cursor cursor = ((SimpleCursorAdapter) parent.getAdapter()).getCursor();
    // Move to the selected contact
    cursor.moveToPosition(position);
    // Get the _ID value
    mContactId = cursor.getLong(CONTACT_ID_INDEX);
    // Get the selected LOOKUP KEY
    mContactKey = cursor.getString(CONTACT_KEY_INDEX);
    // Create the contact's content Uri
    mContactUri = Contacts.getLookupUri(mContactId, mContactKey);
    // ListView Clicked item index

    String id=new String();
    String name = new String();
    String hasPhone = new String();
    int idx;

    Cursor cursor1 = getActivity().getContentResolver().query(mContactUri, null, null, null, null);
    {
        idx = cursor1.getColumnIndex(ContactsContract.Contacts._ID);
        id = cursor1.getString(idx);

        idx = cursor1.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
        name = cursor1.getString(idx);

        idx = cursor1.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
        hasPhone = cursor1.getString(idx);
    }
    Log.i("Phone Number","The phone number is: "+hasPhone);
    Log.i("Name","The name is: "+name);
    /*
     * You can use mContactUri as the content URI for retrieving
     * the details for a contact.
     */
}
