Detect when the user presses on the key Done

What I intend is once the user has entered the data when pressing Done a validation is done

But if the user decides to stop typing and hide the keyboard by pressing the back button, then also detect that event.

the two events can be detected separately. For the first case, we must put a listener that detects the pressure of buttons and with the validate the button of done to perform an action. This is done as follows

final EditText edittext = (EditText) findViewById(R.id.edittext);
edittext.setOnKeyListener(new View.OnKeyListener() {
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            if ((event.getAction() == KeyEvent.ACTION_DOWN) && (keyCode == KeyEvent.KEYCODE_ENTER)) {
                //aqui iria tu codigo al presionar el boton enter o done
                return true;
            }
            return false;
        }
    });

For the second question, it occurs to me to listen when the edittext in question loses focus. for that we use the following code

 EditText txtEdit = (EditText) findViewById(R.id.edittxt);

 txtEdit.setOnFocusChangeListener(new OnFocusChangeListener() {          
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (!hasFocus) {
               // code to execute when EditText loses focus
            }
        }
    });
