Another way would be to use LocalBroadcastManager. The code will be as follows.

//ACTIVITY A CODE

TextView username_tv;
String username;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    username_tv = (TextView) findViewById(R.id.username_tv);

    //Get your username and store it in username
    username = getYourUsername();

    username_tv.setText(username);

    LocalBroadcastManager lbm = LocalBroadcastManager.getInstance(this);
    lbm.registerReceiver(receiver, new IntentFilter("USER_NAME_CHANGED_ACTION"));  
  }

  public BroadcastReceiver receiver = new BroadcastReceiver() {
  @Override
    public void onReceive(Context context, Intent intent) {
      if (intent != null) {
        username = intent.getStringExtra("username");
        username_tv.setText(username);            
      }
  }
};

//ACTIVITY C CODE

//ADD this code to your 'SAVE' Button Listener
Intent intent = new Intent("USER_NAME_CHANGED_ACTION");
intent.putExtra("username", editText.getText().toString());
// put your all data using put extra 
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);

I do not understand why you need this, but you can do it by saving the value of EditText in ActivityC in SparedPreferences here is an example how can make it. Then you should check in onResume() method of ActivityAif there is saved value in SparedPreferences and if has some get the value and set it to "Username" TextView.
