Answer 1

A better approach is to let android handle the orientation change. Android will automatically fetch the layout from the correct folder and display it on the screen. All you need to do is to save the input values of the edit texts in the onSaveInsanceState() method and use these saved values to initialize the edit texts in the onCreate() method.
Here is how you can achieve this:

@Override
protected void onCreate (Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.login_screen);
    ...
    ...
    String userName, password;
    if(savedInstanceState!=null)
    {
        userName = savedInstanceState.getString("user_name");
        password= savedInstanceState.getString("password");
    }

    if(userName != null)
        userNameEdtTxt.setText(userName);
    if(password != null)
        passEdtTxt.setText(password);
}

@Override
    protected void onSaveInstanceState (Bundle outState)
    {
        outState.putString("user_name", userNameEdtTxt.getText().toString());
        outState.putString("password",  passEdtTxt.getText().toString());
    }
