onEditorAction in android

I have two EditTexts and a Button in my layout

an EditText called UserName and another called Password and the Button is called Login

the Button is disabled at the start

what I want is that when ever anything is inputted in EditText UserName and Password the Button should be Enabled

here is what i tried 

@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event)
{
    if(!TextUtils.isEmpty(UserName.getText()) && !TextUtils.isEmpty(PassWord.getText()))
    {
        Login.setEnabled(true);
        return true;
    }

    return false;

when I run this code the Login Button start as disabled and it stays disabled when I input something in both the EditTexts without clicking the Enter Button

it Only works when I click the Enter Button

is there a way to make it work when any button in the keypad is clicked and both of the EditTexts not empty

Thanks for help

You can use TextChangedListener class for EditTexts to listen for events, when the text changes in them. I have a code for this in one of my projects:

private boolean heightFilled;
private boolean weightFilled;

private void setInputListeners() {
    etHeight.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            heightFilled = s.length() > 0;
            calculateButton.setEnabled(heightFilled && weightFilled);
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });

    etWeight.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            weightFilled = s.length() > 0;
            calculateButton.setEnabled(heightFilled && weightFilled);
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });
}

This should work, if you change the names of the Button and the EditTexts.

You need to use a textchanged listener. From in there you can check as typing if both have an input and call code for activating your button there after checks.

   editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

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

        }

        @Override
        public void afterTextChanged(Editable s) {
             //enter code here to check if your edittexts have content
             //then do stuff with your button

            }

        }
    });
