Handle “Enter” in an EditText and insert character in it

I have an EditText. I want that whenever user press enter key, automatically insert a number(incremental numbers). Should I use TextWatcher interface or OnEditorActionListener ? If I use TextWatcher, how to recognize enter key. I do this, but nothing happened.

 View.OnKeyListener onEnter = new View.OnKeyListener() {

        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if ((event.getAction() == KeyEvent.ACTION_DOWN)
                    && (keyCode == KeyEvent.KEYCODE_ENTER)) {
                edtInput.addTextChangedListener(new HandlEventEditText(edtInput));

            }
            return false;
        }
    };

and HandlEventEditText class

public class HandlEventEditText implements TextWatcher {
    @Override
    public void afterTextChanged(Editable s) {
        editText.setText("4");
    }

}

Solution:

Use like this:

editText.setOnKeyListener(new OnKeyListener() {
    public boolean onKey(View view, int keyCode, KeyEvent keyevent) {
        //If the keyevent is a key-down event on the "enter" button
        if ((keyevent.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) {

            //...
            // ...
            // ...    

            return true;
        }
        return false;
    }
});

You can enter the logic there, and your Enter key will do as you say.

Hope it helps.
