How to convert String into Integer in Android or Java:
String strId="29"; int id = Integer.parseInt(strId);
Note:
String must be a number, other wise there should be an exception.
We can use try catch to handle exception or use following function for proper conversion.

int tryParseInt(String number) { try { return Integer.parseInt(number); } catch (NumberFormatException e) { return 0; // in cause of exception we should use any default value. } }
