android - How do i add two listfragment in my app -

-

i have app displays first list using below code. how display on more list on click of list item below code. please me example code. 

public class mylistfragment1 extends listfragment {      string[] videosetup ={             "properties",              "color control",              "tint",              "3d depth",             "3d format",              "dynamic backlight",              "mode",              "cache id",      };      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         listadapter mylistadapter = new arrayadapter<string>(                 getactivity(),                 android.r.layout.simple_list_item_1,                 videosetup);         setlistadapter(mylistadapter);     }      @override     public view oncreateview(layoutinflater inflater, viewgroup container,             bundle savedinstancestate) {         return inflater.inflate(r.layout.listfragment1, container, false);     }      @override     public void onlistitemclick(listview l, view v, int position, long id) {         // todo auto-generated method stub         toast.maketext(                 getactivity(),                  getlistview().getitematposition(position).tostring(),                  toast.length_long).show();         fragment2 frag = (fragment2) getfragmentmanager().findfragmentbyid(r.id.fragment2);     }     }

i not sure of doing this. new android.

first of must write second listfragment. similarly.

then, in onlistitemclick() method of first fragment can write this:

fragment2 frag = (fragment2) getfragmentmanager().findfragmentbyid(r.id.fragment2);  activity.getfragmentmanager()                     .begintransaction()                     .replace(r.id.fragment_container, frag)                     .addtobackstack(null)                     .commit();

this fragment container - /res/layout/activity_main.xml. empty. bind mainactivity.class setcontentview(r.layout.activity_main):

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"                 xmlns:tools="http://schemas.android.com/tools"                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 tools:context=".mainactivity"                 android:background="#000000"                 android:id="@+id/fragment_container"> </relativelayout>

after have add new first fragment on fragment container described above.

then, in onlistitemclick(...) method of first fragment have create new second fragment , replace first.

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
