Is there a way to fire an event when the contents of an EditText view have changed?

I’d like to listen when the user changes a edit text in order to formatting it. Is there some kind of listener or interface I can use for that? Thanks

What you’re looking for is probably a TextWatcher, check this link for more information. Here’s how to implement it:

editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {}
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
    @Override
    public void afterTextChanged(Editable s) {}
});
