How to retrieve SharedPreferences and send that data to firebase realtime database

Question

I am developing a Matrimony, I have multiple pages to store data that's why I have used SharedPreferences. I have pages like Basic Details,Social Details,Career Details,Login Details and on Login Details I want to retrieve the stored data from SharedPreferences and send that data to firebase realtime database.How can I do that?

This is the snippet for database:

This is the snippet for the child nodes:

I have tried to pass the SharedPreferences object "sp" but because of it a new node is generated i.e. "all" Below is the code of Login details

public class LoginDetails extends AppCompatActivity {
    EditText etemail_id,etpassword;
    TextView tvlogin_details;
    Button btregister,btback;
    FirebaseAuth mAuth;
    FirebaseDatabase database;
    DatabaseReference reference;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.login_details);
        etemail_id = (EditText) findViewById(R.id.etEmailid);
        etpassword = (EditText) findViewById(R.id.etPassword);

        tvlogin_details = (TextView) findViewById(R.id.tvLoginDetails);
        btback = (Button) findViewById(R.id.btBack);
        mAuth = FirebaseAuth.getInstance();
        btregister = (Button) findViewById(R.id.btRegister);
        database=FirebaseDatabase.getInstance();
        reference=database.getReference();
        //users= String.valueOf(new Users());

        btregister.setOnClickListener(new View.OnClickListener() {

            private final String PREFERENCE_FILE_KEY = "myAppPreference";

            @Override
            public void onClick(View view) {
                final String email = etemail_id.getText().toString().trim();
                final String password = etpassword.getText().toString().trim();

                if (TextUtils.isEmpty(email)) {
                    etemail_id.setError("Provide your Email first!");
                    etemail_id.requestFocus();
                }
                else if (TextUtils.isEmpty(password)) {
                    etpassword.setError("Enter Password!");
                    etpassword.requestFocus();
                }
                else if (!(email.isEmpty() && password.isEmpty())) {
                    mAuth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(LoginDetails.this, new OnCompleteListener<AuthResult>() {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task) {
                            if (task.isSuccessful()) {

                                reference.addValueEventListener(new ValueEventListener() {
                                    @Override

                                        reference.child("User").child(Objects.requireNonNull(mAuth.getUid())).setValue(sp);
                                        Toast.makeText(getApplicationContext(), "data entered", Toast.LENGTH_SHORT).show();
                                    }
                                    @Override

                                    }
                                });
                                Toast.makeText(LoginDetails.this, "Successfully registered", LENGTH_LONG).show();
                                Intent it = new Intent(getApplicationContext(), Login.class);
                                startActivity(it);
                            }

                            else {
                                Toast.makeText(LoginDetails.this, "Registration Error", LENGTH_LONG).show();
                            }
                        }
                    });
                }
                else {
                    Toast.makeText(LoginDetails.this, "Error", Toast.LENGTH_SHORT).show();
                }
             }
        });

        btback.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent it1 = new Intent(getApplicationContext(), Preferences.class);
                startActivity(it1);
            }
        });
    }
}

I expected the result to be User->authkey->mydata.

The output was User->authkey->all->mydata

uncomment the commented line in `onDataChange` and remove the line below that commented line — Jimale Abdi, Oct 31 '19 at 09:52

You might be encountering this issue because the of the structure of the SharedPreferences file.

Try arranging your info in a new HashMap that has all the info you need in it as key : value and than try sending the new HashMap as the value to FireBase

Example :

HashMap hashMap = new HashMap();

SharedPreferences sp = getSharedPreferences("Mypref", 0);
hashMap.put("first_name", sp.getString("first_name", null))
hashMap.put("last_name", sp.getString("last_name",null))
hashMap.put("fathers_name", sp.getString("fathers_name", null))
hashMap.put("date", sp.getString("date", null))
hashMap.put("income", sp.getString("income", null))
(.......)

reference.child("User").child(Objects.requireNonNull(mAuth.getUid())).setValue(hashMap);

If that is not the case, you'll most probably need to iterate on the list of details you have and set one at a time as a value under your user's UID .

Example:

Use the HashMap we built in the first attempt :

Iterator iterator = hashMap.entrySet().iterator() 
if (hashMap.hasNext()) {
    iterator.next() 
    reference.child("User").child(Objects.requireNonNull(mAuth.getUid())).child(iterator.getKey).setValue(iterator.getValue);
}

@ReetuJaiswal Glad to hear, is it the second one that worked eventually? And if the answer helped you than please select it as the correct answer for future seekers. — Itay Feldman, Oct 31 '19 at 10:39
