Question

I have an EditText textBox and I would like to react to the user typing inside of it.
Note: I want to react while the user types in the EditText so I can’t have some kind of button for the user to click when he is done.

You can use something like this (textchangelistener): If you want listen usertype on edittext

 EditText yourtext = (EditText)findViewById(R.id.medittext);
        yourtext.addTextChangedListener(new TextWatcher() {

            @Override
            public void afterTextChanged(Editable s) {
                // TODO Auto-generated method stub

            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {

                doSomething();



            } 

        });

Hope it helps
