Question

I have this code:

EditText value = ( EditText )findViewById( R.id.editbox );
Integer int_value = Integer.valueOf( value.getText().toString() );

It works great when there are a number in the EditText, but it FC my application when it is empty or have text, etc.

How can I make sure that int_value have/are a number? I also tried parseInt but with the same result.

Answer 1

  try {             
Integer int_value  = Integer.parseInt(value.getText().toString());
            } catch (NumberFormatException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
        }
