You use a TextWatcher :

myEditText.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) {

}

});

Put you code inside afterTextChanged

Yes you can. attach your EditText with an addTextChangedListener()

        your_editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if (!TextUtils.isEmpty(s) ){
                //TODO filter data here
            }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    });
