Not able to parse fields with underscores

Question

I have a column name viewed_by on Firebase server

Test
  |
  |--viewed_by: 30 

On the app I have a POJO class which has the member viewed_by

Test.class has member

private int viewed_by;

In onDataChange function when I receive the data, I get the Test object using the getValue function

Test t = dataSnapshot.getValue(Test.class);

But I get the value as 0 instead of 30.

If I change the field name from viewed_by to viewedBy (both on server and POJO class), I get the expected value (30)

Is it a parsing issue in getValue function? Or the field name are not supposed to have underscores in the name?

Answer 1

Jus figured it out, had to change the function names as well from ViewedBy to Viewed_By for it to work with viewed_by field

/**
 *
 * @return
 * The viewed_by
 */
public int getViewed_By() {
    return viewed_by;
}

/**
 *
 * @param viewed_by
 * The viewed_by
 */
public void setViewed_By(int viewed_by) {
    this.viewed_by = viewed_by;
}
