Subtract at runtime in Android

Question

I have three edittext named et1,et2,et3. I want to subract et1 and et2 and show the answer in et3. But this should be done without clicking any button. As soon as I write values in et1 and et2, the calculations have to be done and displayed in et3.

Thank You, Spandan Joshi

As the answer suggests, just try and find how to add a `TextWatcher` to your edittexts. — Vucko, Jul 08 '16 at 07:33

You will need to use addTextChangedListener() on edittext.

Hope it will help you!
