Why does this error message occur to me? What should I do? I think that maybe is because of my double variable of weight.
line 111 is double weight = Double.parseDouble(Weight); in this method calculatepaymentbutton.setOnClickListener(new View.OnClickListener()
I wonder there is a way to eliminate this problem? Cause what I want to do is that when I click calculatepaymentbutton, I want my system to check that all EditText is all filled or not, but when I click it this error logcat occur~
These comparisons are part of the problem:
if (ParcelIDCal == "" || Quantity == "" || Weight == "" || Type == "")
They should be:
if (ParcelIDCal == null || ParcelIDCal.trim().equals("") ||
Quantity == null || Quantity.trim().equals("") ||
Weight == null || Weight.trim().equals("") ||
Type == null || Type.trim().equals(""))
And all the parts where you're comparing strings like this are wrong:
Type == "document"
That's not how you compare Strings for equality in Java, you must use:
Type.equals("document")
Or even better, to take into consideration the possibility that the variable is null it's better to do this:
"document".equals(Type)
And by the way - variables and attributes in Java should start with a lowercase letter, it's the convention.
