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

Surround the offending lines with a try/catch block.

try {
    Log.d("Month" , monthlyTest);
    Log.d("freeMonths" , freeMonths);                               
    monthlyFeeforChannel =  Integer.parseInt(monthlyTest);                                      
    MonthlyFee.add(monthlyFeeforChannel);
    FreePeriod.add(freeMonths);
}
catch (NumberFormatException nfe) {
    nfe.printStackTrace();
    // Alert the user/log the error, etc.
}

Answer 2

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!!!}

Answer 3

I think, you should have to add this to your edit text

editText.setHint("0");

Answer 4

In the aboue code you have used like converting String to Integer in that case you will not convert ""(Empty String) to Integer

Integer.parseInt(monthlyTest);  // Here monthyTest value is ""

Please make sure the string is not empty befor conversion.

Check the length of the String is should be greater than 0.

if(monthlyTest.length()>0)

Thanks.....

Answer 5

try

if(monthlyTest == null || monthlyTest.trim().equals("")){

You could also use

if(monthlyTest == null || monthlyTest.trim().isEmpty()){
