private void loadPref() {
    SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

    boolean isTrue = sharedPreferences.getBoolean("Guest_Mode_Key", true);
    if (isTrue) {
        View Guest =  findViewById(R.id.guest_include);
        View User = findViewById(R.id.user_include);
        Guest.setVisibility(View.VISIBLE);
        User.setVisibility(View.GONE);


    } else {
        View Guest =  findViewById(R.id.guest_include);
        View User = findViewById(R.id.user_include);
        Guest.setVisibility(View.GONE);
        User.setVisibility(View.VISIBLE);
    }
}

.

<include
    android:id="@+id/guest_include"
    layout="@layout/content_one"
    android:visibility="visible" />

<include
    android:id="@+id/user_include"
    layout="@layout/content_two"
    android:visibility="gone" />

I created two <*include> tags and set the first to "Visible" and the second "Gone", i found how to get the data from the settings activity it was simple and then i created an if when the switch is true etc. and for the end i just call loadPref()

@DaveNOTDavid - I was lucky after all ;)
