Android: converting String to int

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.

try this

String t1 = name.getText().toString();
Integer t2 = Integer.parseInt(mynum.getText().toString());

boolean ins = myDB.adddata(t1,t2);

public boolean adddata(String name, Integer price)

// Convert String to Integer

// String s = "fred";  // use this if you want to test the exception below


String s = "100"; 
try
{
  // the String to int conversion happens here
  int i = Integer.parseInt(s.trim());

  // print out the value after the conversion
  System.out.println("int i = " + i);
}
catch (NumberFormatException nfe)
{
  System.out.println("NumberFormatException: " + nfe.getMessage());
}
