我有用户得分5.我想要用得分为6的用户更新。你能帮助我。
ParseUser user = ParseUser.getCurrentUser();
if (user == null){
return;
}
if (userName.equals(user.getUsername())) {
user.put(PlayerModel.PARSE_FIELD_SCORE_PLAYER,
6);
user.signUpInBackground(new SignUpCallback() {
@Override
public void done(final ParseException e) {
if (e != null) {
Log.e(">>>>>PlayerProvider",e.getMessage());
}
}
});
}
我改变相同的代码后,但没有成功。你能帮帮我吗?
user.saveInBackground(new SaveCallback() {
public void done(com.parse.ParseException e) {
// TODO Auto-generated method stub
if (e != null) {
Log.e(">>>>>PlayerProvider",e.getMessage());
} else {
}
}
});

您可以使用incremen
。
文档:https://parse.com/docs/android/guide#objects-counters
前:
ParseUser user = ParseUser.getCurrentUser();
user.incremen(PlayerModel.PARSE_FIELD_SCORE_PLAYER);
user.saveInBackground();
编辑:
ParseUser user = ParseUser.getCurrentUser();
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.getInBackground(user.getObjectId(), new GetCallback<ParseUser>() {
@Override
public void done(ParseUser parseUser, ParseException e) {
if (e == null) {
parseUser.put(PlayerModel.PARSE_FIELD_SCORE_PLAYER, 9999);
parseUser.saveInBackground();
}
}
});
