Question

我正在尝试从Parse.com中的ParseUser中删除一个实现。我试图在互联网上找到如何做到这一点，但我没有成功。这里有人可以帮帮我吗？还是给我一些线索？它似乎无法为我提供帮助。

我尝试了以下代码：

@Override
public void onDismiss(final AbsListView listView,
        final int[] reverseSortedPositions) {

    for (int position : reverseSortedPositions) {

        ParseQuery<ParseUser> query = ParseUser.getQuery();
        query.whereEqualTo("username", values.get(position));
        query.findInBackground(new FindCallback<ParseUser>() {
            public void done(List<ParseUser> objects, ParseException e) {

                if (objects.size() != 0) {
                    if (objects.get(0).getUsername() != null) {



                        final ParseUser currentUser = ParseUser
                                .getCurrentUser();
                        if (currentUser != null) {
                            {

                                final ParseObject friend = new ParseObject(
                                        "Friends");
                                friend.remove(values.get(position));

                                friend.deleteInBackground(new DeleteCallback() {

                                    @Override
                                    public void done(ParseException e) {
                                        ParseRelation relation = currentUser
                                                .getRelation("Friends");
                                        relation.remove(friend);
                                        Toast.makeText(getApplicationContext(),
                                        "Player Has Been
                                        Remove"+values.get(position),
                                        Toast.LENGTH_SHORT).show();

                                        currentUser.saveInBackground();
                                    }
                                });
                });

                                Toast.makeText(getApplicationContext(),
                                        "Player Has Been Added",
                                        Toast.LENGTH_SHORT).show();

                            }
                        }

                        //dialog.hide();
                    }

                } 
            }
        });

        adapt.remove(values.get(position));
        adapt.notifyDataSetChanged();

    }


}

拜托，我需要你的帮助。抱歉我的英语很差

尝试将代码修改为此，我猜测将模板设置为ParseObject对于将关系链接到用户非常重要。

ParseRelation<ParseObject> relation = currentUser.getRelation("Friends");
relation.remove(friend);
Toast.makeText(getApplicationContext(), "Player Has Been Add2321434243ed",Toast.LENGTH_SHORT).show();
currentUser.saveInBackground();

从Parse.com android中的ParseUser中删除关系
