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.

Change

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

to

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