You can use TextWatcher like below code:

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) {

}
});
