How to store multiple items in firebase using push() - firebase-realtime-database

Question

I am trying to get the following to be inserted into firebase but read that we can only store one information at a time? I thought that we can somehow store multiple information under a single unique id? Below is the code and I am trying to insert information such as phone numbers, address etc. With the address, can we use a string for the whole address or must we break it down to integer plus string? Also, should i be using "long" for phone number? I am also not sure if I should be using multiple Firebasedatabase for this?
public class MainActivity extends AppCompatActivity {
private Button logout;
private EditText edit;
private EditText number;
private EditText address;
private EditText phone;
private EditText postcode;
private Button add;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
logout = findViewById(R.id.logout);
edit = findViewById(R.id.edit);
add = findViewById(R.id.add);
number = findViewById(R.id.number);
address = findViewById(R.id.address);
phone = findViewById(R.id.phone);
postcode = findViewById(R.id.postcode);
logout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
FirebaseAuth.getInstance().signOut();
Toast.makeText(MainActivity.this, "Logged Out", Toast.LENGTH_SHORT).show();
startActivity(new Intent(MainActivity.this, StartActivity.class));
finish();
}
});
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String txt_name = edit.getText().toString();
// int txtnumber = Integer.valueof(number);
String txt_address = address.getText().toString();
// Long phone_number = Long.parseLong(phone.getText().toString().trim());
// Long postcode2 = Long.parseLong(postcode.getText().toString().trim());
if (txt_name.isEmpty()) {
Toast.makeText(MainActivity.this, "No name entered!", Toast.LENGTH_SHORT).show();
} else {
FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference().child("Medical Clinic").push().child("Name").setValue(txt_name, txt_address);
// FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference().child("Medical Clinic").setValue(txt_address);
// FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference().child("Medical Clinic").child("Name:").child("Address No:").child("Address Name:").setValue(txt_address);
// FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference().child("Medical Clinic").child("Name:").child("Address No:").child("Address Name").child("Phone number:").setValue(phone_number);
// FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference().child("Medical Clinic").child("Name:").child("Address No:").child("Address Name").child("Phone number:").child("Postcode:").setValue(postcode2);
}
}
});
}
}

Answer 1

Create a class named Info
public class Info {
private String name;
private String address;
private String phoneNo;
private String postcode;
public Info(String name, String address, String phoneNo, String postcode) {
this.name = name;
this.address = address;
this.phoneNo = phoneNo;
this.postcode = postcode;
}
public Info() {
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getPhoneNo() {
return phoneNo;
}
public void setPhoneNo(String phoneNo) {
this.phoneNo = phoneNo;
}
public String getPostcode() {
return postcode;
}
public void setPostcode(String postcode) {
this.postcode = postcode;
}
}
then in your activity
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String txt_name = edit.getText().toString();
// int txtnumber = Integer.valueof(number);
String txt_address = address.getText().toString();
// Long phone_number = Long.parseLong(phone.getText().toString().trim());
// Long postcode2 = Long.parseLong(postcode.getText().toString().trim());
if (txt_name.isEmpty()) {
Toast.makeText(MainActivity.this, "No name entered!", Toast.LENGTH_SHORT).show();
} else {
String key = FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference().child("Medical Clinic").push().getKey();
Info info = new Info(name,String.valueOf(txtnumber),String.valueOf(phone_number),String.valueOf(postcode2));
FirebaseDatabase.getInstance("https://medical-review-in-australia.firebaseio.com/").getReference().child(key).setValue(info);
});
