android - User login can'd identify user position -
user register student or tutor during registration saved in firebase database when login cannot identify user position saved in firebase database should do? please can give suggestion or advice me how this.
the database save uid email authentication node under root rest details children of uid.
the code this
private firebaseauth auth; private edittext un, pw; private string getun, getpw, uid; private button bl; private firebasedatabase db; private databasereference ref; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_login); auth = firebaseauth.getinstance(); db = firebasedatabase.getinstance(); ref = db.getreference(); uid = auth.getcurrentuser().getuid(); ref = db.getreference("users").child(uid); un = (edittext) findviewbyid(r.id.lun); pw = (edittext) findviewbyid(r.id.lpw); bl = (button) findviewbyid(r.id.lbt); final textview rl = (textview) findviewbyid(r.id.lreg); //login bl.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { getun = un.gettext().tostring().trim(); getpw = pw.gettext().tostring().trim(); loginaction(getun, getpw); } }); //open register page rl.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { intent ri = new intent(login.this,register.class); login.this.startactivity(ri); } }); } private void loginaction(string a, string b){ auth.signinwithemailandpassword(a, b).addoncompletelistener(this, new oncompletelistener<authresult>() { @override public void oncomplete(@nonnull task<authresult> task) { log.d("login", "login success" + task.issuccessful()); if (!task.issuccessful()) { log.w("login", "login failed", task.getexception()); toast.maketext(login.this, "login failed. please try again", toast.length_short).show(); }else{ toast.maketext(login.this, "login success", toast.length_short).show(); ref.orderbychild("position").addvalueeventlistener(new valueeventlistener() { @override public void ondatachange(datasnapshot datasnapshot) { string ps = datasnapshot.getvalue().tostring(); if(ps.equalsignorecase("student")){ intent = new intent(login.this, studenthomepage.class); startactivity(i); }else if (ps.equalsignorecase("tutor")){ intent = new intent(login.this, tutorhomepage.class); startactivity(i); }else{ toast.maketext(login.this, "wrong input. please check again email , password.", toast.length_short).show(); return; } } @override public void oncancelled(databaseerror databaseerror) { } }); } // ... } }); }
create 2 child nodes users. 1 students , 1 tutors.(give both child values value of true, otherwise firebase doesn't save children.)
have 2 registration buttons ..one students , 1 tutors. registration tutor code.....
mregistration.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { final string email = memail.gettext().tostring(); final string password = mpassword.gettext().tostring(); mauth.createuserwithemailandpassword(email,password).addoncompletelistener(driverloginactivity.this, new oncompletelistener<authresult>() { @override public void oncomplete(@nonnull task<authresult> task) { if (!task.issuccessful()){ toast.maketext(tutorsloginactivity.this, "sign in error", toast.length_short).show(); }else{ string user_id= mauth.getcurrentuser().getuid(); databasereference current_user_db= firebasedatabase.getinstance().getreference().child("users").child("tutors").child(user_id); current_user_db.setvalue(true); } } }); } }); do same students. change .child("tutors") .child("students") give uids 2 different groups. , can same when logging in. think better way proceed.
