我务实地创建的android手机联系人组中没有删除选项。请帮我。我不知道如何删除电话的联系人组。默认情况下，电话联系人下有“家庭”、“朋友”和“工作”3 个组，出于测试目的，我创建了一个名为“测试”的组并为该组分配了一个联系人。现在的问题是，我没有看到删除此自定义组的任何选项。任何想法？

group="Test";

if (group != null) {

    String GroupId = getGroupId();
    ops.add(ContentProviderOperation.newInsert(ContactsContract.Data.CONTENT_URI)
            .withValueBackReference(ContactsContract.Data.RAW_CONTACT_ID, 0)
            .withValue(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.GroupMembership.CONTENT_ITEM_TYPE)
            .withValue(ContactsContract.CommonDataKinds.GroupMembership.GROUP_ROW_ID, GroupId)
            .build());

}

private String getGroupId()
{
    String GroupId = ifGroup(group);
    if (GroupId == null)
    {

        ArrayList<ContentProviderOperation> opsGroup = new ArrayList<ContentProviderOperation>();
        opsGroup.add(ContentProviderOperation.newInsert(ContactsContract.Groups.CONTENT_URI)
                .withValue(ContactsContract.Groups.TITLE, group)
                .withValue(ContactsContract.Groups.GROUP_VISIBLE, true)
                .withValue(ContactsContract.Groups.DELETED, true)
                .withValue(ContactsContract.Groups.ACCOUNT_NAME, group)
                .withValue(ContactsContract.Groups.ACCOUNT_TYPE, group)
                .build());
        try
        {

            getContentResolver().applyBatch(ContactsContract.AUTHORITY, opsGroup);
        } catch (Exception e)
        {
            e.printStackTrace();
        }
    }

    return ifGroup(group);
}
//### Function return group id by Group Title
private String ifGroup(String $name)
{
    String selection = ContactsContract.Groups.DELETED + "=? and " + ContactsContract.Groups.GROUP_VISIBLE + "=?";
    String[] selectionArgs = { "0", "1" };
    Cursor cursor =getContentResolver().query(ContactsContract.Groups.CONTENT_URI, null, selection, selectionArgs, null);
    cursor.moveToFirst();
    int len = cursor.getCount();

    String GroupId = null;
    for (int i = 0; i < len; i++)
    {
        String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Groups._ID));
        String title = cursor.getString(cursor.getColumnIndex(ContactsContract.Groups.TITLE));

        if (title.equals(group))
        {
            GroupId = id;
            break;
        }

        cursor.moveToNext();
    }
    cursor.close();

    return GroupId;
}
