我使用以下代码来获取数据表单 objectId：
ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("User");
query.getInBackground("U8mCwTHOaC", new GetCallback() {
public void done(ParseObject object, ParseException e) {
Log.d(">>>", "0000>>>" +objid);
dlg.dismiss();
if (e == null) {
// object will be your game score
Log.d(">>",">>"+object);

if you want to get data from user table.
如果你想从用户表中获取数据。
ParseQuery<ParseObject> query = ParseQuery.getQuery("_User");
query.whereEqualTo("objectId","U8mCwTHOaC");
query.findInBackground(new FindCallback<ParseObject>() {
public void done(List<ParseObject> objects, ParseException e) {
if (e == null) {
// row of Object Id "U8mCwTHOaC"
} else {
// error
}
}
});
if you want the row of current user
如果你想要当前用户的行
ParseQuery<ParseObject> query = ParseQuery.getQuery("_User");
query.whereEqualTo("objectId",ParseUser.getCurrentUser().getObjectId());
query.findInBackground(new FindCallback<ParseObject>() {
public void done(List<ParseObject> objects, ParseException e) {
if (e == null) {
// row of Object Id "Current USer"
} else {
// error
}
}
});
