If you maintain two layouts, all UI thread should be terminated.

If you use AsynTask, then you can easily call .cancel() method inside onDestroy() method of current activity.

@Override
protected void onDestroy (){
    removeDialog(DIALOG_LOGIN_ID); // remove loading dialog
    if (loginTask != null){
        if (loginTask.getStatus() != AsyncTask.Status.FINISHED)
            loginTask.cancel(true); //cancel AsyncTask
    }
    super.onDestroy();
}

For AsyncTask, read more in "Cancelling a task" section at here.

Update: Added condition to check status, as it can be only cancelled if it is in running state. Also note that the AsyncTask can only be executed one time.
