cocktaildetail class

in menu class, passing hard coded string :

   ourintent.putextra("cocktail_name",**"bloodymary"**); 

change value retrieved listview :

    string selectedfromlist =(string) (l.getitematposition(position));     ourintent.putextra("cocktail_name",selectedfromlist); 

also in cocktail class, oncreate, again setting text hardcoded string. using bundle, retrieve value , settext;

  bundle bundle = getintent().getextras();   //extract data…  string name = bundle.getstring(“cocktail_name”);   textview t1 = (textview)findviewbyid(r.id.textcocktailname);  t1.settext(name);
