I have a problem with two EditText in particular, these are in a fragment , the first time I arrive at the fragment, these are empty I assign them a number
( ej: et1 = 1, et2 = 2; )
I do all the operations in a normal way, I leave the fragment and replace it with another one, when I return to the fragment with the EditText and I return them to enter values
( ej: et1 = 5, et2 = 6;)
when doing a et1.getText().toString(); it returns the value 1 instead of the new value that is 5
What could I be doing wrong?
the value of EditText are assigned by user
I enclose the code for a better understanding
