Display a layout in function of a variable

Thanks Ben Jakuben for your tuto. I try to do the Blog Reader but in local. 

public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            Intent intent = getIntent();
            String townNameDev = intent.getStringExtra("town_name_dev");

            int resID = this.getResources().getIdentifier(townNameDev, "layout", this.getPackageName());
            LinearLayout layout = (LinearLayout)findViewById(resID);
        }

I can't do this : //setContentView(R.layout.townNameDev); so I load the ressource but I don't know how to display it. I need to load xml files in function of townNameDev.

Thanks you for your help

That setContentView() line is very important, so let's start by troubleshooting why that isn't working. When you try to include that line, what error do you get?

townNameDev was a variable but it's stupid to create many layouts just for display differents images. So I do something else. I load my images on an ImageView in a single same layout. Here's https://play.google.com/store/apps/details?id=com.jumpou.Drawy , my app do with your course, if you're curious of what I wanted do ;) Thanks you very much Ben and Treehouse. Please continue, do others android tutorials ! Where you create and use some custom classes ;) A game will be perfect ^^
