Develop Reference

update one or more fields inside of a document, without updating all the fields

I have a feature in my program where I have to enter the user's details such as the user's age, height, and weight. This data will be stored in Firestore.
this is how the user will input their details

public class account_information extends AppCompatActivity {
public static final String TAG = "TAG";
EditText et_age, et_height, et_weight;
Button btn_create;
FirebaseFirestore db;
FirebaseAuth mAuth;
String userID;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_account_information);
mAuth = FirebaseAuth.getInstance();
db = FirebaseFirestore.getInstance();
et_age = findViewById(R.id.et_age);
et_height = findViewById(R.id.et_height);
et_weight = findViewById(R.id.et_weight);
btn_create = findViewById(R.id.btn_create);
btn_create.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String age = et_age.getText().toString().trim();
String height = et_height.getText().toString().trim();
String weight = et_weight.getText().toString().trim();
if(age.isEmpty()){
et_age.setError("Age is mandatory");
et_age.requestFocus();
return;
}
if(height.isEmpty()){
et_height.setError("Height is mandatory");
et_height.requestFocus();
return;
}
if(weight.isEmpty()){
et_weight.setError("Weight is mandatory");
et_weight.requestFocus();
return;
}
userID = mAuth.getCurrentUser().getUid();
DocumentReference documentReference = db.collection("userDetail").document(userID);
Map<String,Object> user = new HashMap<>();
user.put("Age",age);
user.put("Height",height);
user.put("Weight",weight);
user.put("UserId", userID);
documentReference.set(user)
.addOnSuccessListener((OnSuccessListener) (aVoid) -> {
Log.d(TAG, "onSuccess: user Detail is created for "+ userID);
startActivity(new Intent(account_information.this, MainActivity.class));
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull #NotNull Exception e) {
Log.d(TAG, "onFailure"+ e.toString());
}
});
}
});
}
}
And this is how it will store in firebase

However, when the user decides to update their profile (for example his weight) the rest of the input will pass an empty string at the firebase
like this:

return true;
}
}

You are passing all three fields (age, height, weight) without checking if they are valid or contain changes to the existing data. You should make those checks before calling update, similar to how you did in the create function.
For example, create a function to check if new data is valid and different than old data:
boolean isValidAndChanged(DocumentReference docRef, String key, String value) {
// TODO get snapshot of data and compare to new value
}
And then use that to update (passing a Map to update instead of var-args):
String age = et_age.getText().toString().trim();
String height = et_height.getText().toString().trim();
String weight = et_weight.getText().toString().trim();
userID = mAuth.getCurrentUser().getUid();
DocumentReference documentReference = mStore.collection("userDetail").document(userID);
Map<String, String> dataToUpdateMap = new HashMap<>();
if (isValidAndChanged(documentReference, "Age", age)) {
dataToUpdateMap.put("Age", age);
}
if (isValidAndChanged(documentReference, "Height", height)) {
dataToUpdateMap.put("Height", height);
}
if (isValidAndChanged(documentReference, "Weight", weight)) {
dataToUpdateMap.put("Weight", weight);
}
documentReference.update(dataToUpdateMap)
// ...
Also, best practice is to use constants instead of passing magic strings around all over your code (e.g. "Age" becomes AGE.)

You're getting all the data overwritten because you're passing empty strings to the update() method. Firestore can indeed hold null values, but the values of Age and Height after the update are not null, but empty strings.
If you want to update a single field and leave the other ones untouched, then you should simply pass to the update() method only values for the fields you need to update. In code, it should look like this:
documentReference.update("Weight", weight).addOnSuccessListener(/* ... /*);

How to use snapshot result, in a firebase transaction

0
I have a Scores node in my database. At the moment, I can update the score after a game. For the purposes of creating a leaderboard, I want to add the users username to the node as well. I have tried to use Transactions that take a snapshot, to get the current logged in username, that when the score is updated, the name will also be added to the Scores node.
I can retrieve the username using my transaction, but cant figure out how to pass this value, to the Scores node.
This is what I have so far, this code allows me to update the "Points" in the scores node, and allows me to retrieve the name of the logged in user, but not set this value in the Scores node of the database:

How to read and display user's rank which is set as default in the beginning

I added a new column COL_5 to my SQLite database and it's called "rank". Every user registered starts with rank set as "Australopithecus afarensis" which should be displayed in UserPanelActivity.java. What I did is I managed to display nickname of user (SignInActivity) but I have trouble with checking current rank and then display it on the screen.
Code looks like this:
DatabaseHelper:

public static final String COL_4 ="password";
public static final String COL_5 = "rank";
//public static final String COL_6 = "dailytip";
public DatabaseHelper(#Nullable Context context) {

}
#Override

}

}

ContentValues contentValues = new ContentValues();
contentValues.put("username", user);
contentValues.put("password", password);
contentValues.put("mail_address", mail_address);
long res = db.insert("registeruser", null, contentValues);
db.close();
return res;
}
public boolean checkUser(String username, String password)
{
String[] columns = {COL_1};
SQLiteDatabase db = getReadableDatabase();
String selection = COL_2 + "=?" + " and " + COL_4 + "=?";
String[] selectionArgs = {username, password};
Cursor cursor = db.query(TABLE_NAME, columns,selection,selectionArgs,null,null,null);

Every help is kindly seen, thanks in advance :)

Create a method like this in your DatabaseHelper class:
public String getRank(int id) {
String query = "SELECT rank from " + TABLE_NAME + " where ID = " + id;
SQLiteDatabase db = getReadableDatabase();
try {
return db.rawQuery(query, null).getString(cursor.getColumnIndex(rank));
} catch (Exception e) {
return "";
}
}

}
});
}
}
I don't know what type of code is necessary and where should I add?

Try this lib:
CountryCodePicker
dependencies {
implementation 'com.hbb20:ccp:2.2.2'
}
In XML
<com.hbb20.CountryCodePicker
android:id="#+id/country_picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:gravity="center|center_vertical"
android:includeFontPadding="false"
android:textColor="#color/text_black"
app:ccp_showNameCode="false"
app:ccp_textSize="#dimen/small_text_size" />
In Activity
CountryCodePicker country_picker = findViewById(R.id.country_picker);
String country_code = country_picker.getSelectedCountryCode();

Will post more code IF needed.
Thank you very much.

"," should be removed after price in the above code. Below is the rite code
String query = String.format("INSERT INTO OrderDetail(ProductId,ProductName,Quantity,Price)VALUES('%s','%s','%s','%s');",
order.getProductId(),
order.getProductName(),
order.getQuantity(),
order.getPrice());
Also remove "," from below code above
String[] sqlSelect={"ID","ProductName","ProductId","Quantity","Price"};
