Is there a way to clear edittext before bluetooth barcode scanner input

Question

I have an Edittext and I want to clear it before receiving the input from the next scan by barcode scanner. The problem is that every time I scan a barcode, the input is added to the result of previous scan like this:

id=3id=12id=34

I tried beforeTextChanged event and it doesn't work for me!
