如何删除以特定名称开头的所有 android 个联系人？

Question

我想从 android phone 中删除所有以 "AAA" 开头或包含 "AAA" 的联系人。这是我尝试过的：

private void deleteContact(String name) {

        ContentResolver cr = getContentResolver();
        String where = ContactsContract.Data.DISPLAY_NAME + " = ? ";
        String[] params = new String[] {"AAAA"};

        ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
        ops.add(ContentProviderOperation.newDelete(ContactsContract.RawContacts.CONTENT_URI)
                .withSelection(where, params)
                .build());
        Log.e(",,,,",String.valueOf(ops.get(0)));
        try {


            cr.applyBatch(ContactsContract.AUTHORITY, ops);
        } catch (RemoteException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (OperationApplicationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        Toast.makeText(NativeContentProvider.this, "Deleted the contact with name '" + name +"'", Toast.LENGTH_SHORT).show();

    }

但失败了。请给我一些想法，以便我可以继续我的项目。

也许这会让您走上正轨：

ContentResolver mContentResolver = getContentResolver();
    private int deleteContactsLike(String name) {
    return mContentResolver.delete(
            ContactsContract.RawContacts.CONTENT_URI,
            ContactsContract.Contacts.DISPLAY_NAME
            + " like ?",
            new String[] { name + '%'});
