Edit Text shows exception Invalid Int “”

Question

I have already tried setting the EditText default value to be zero but when it comes to editing and erase as \"\" ( empty space , no more wordings _ in the Edit Text field <

Answer 1

If the input type is set to number you cannot test for "null" so the best solution is to test if length is zero, this way:

if(number.length() == 0) {EditText is empty!!!}
