Android: converting String to int

Question

I'm simply trying to convert a string that is generated from a barcode scanner to an int so that I can manipulate it by taking getting the remainder to generate a set number of integers. So far I have tried:

int myNum = 0;  try {     myNum = Integer.parseInt(myString.getText().toString()); } catch(NumberFormatException nfe) {  }  

and

Integer.valueOf(mystr); 

and

int value = Integer.parseInt(string);  

The first one gives me the error :The method getText() is undefined for the type String while the last two don't have any compile errors but the app crashes immediately when those are called. I thought it had to do with my barcode scanning intent method but I put it into the OnCreate and still got the error.

Answer 1

Change

try {     myNum = Integer.parseInt(myString.getText().toString()); } catch(NumberFormatException nfe) { 

to

try {     myNum = Integer.parseInt(myString); } catch(NumberFormatException nfe) { 

Answer 2

It's already a string? Remove the getText() call.

int myNum = 0;  try {     myNum = Integer.parseInt(myString); } catch(NumberFormatException nfe) {   // Handle parse error. }
