Check fragment is presented in framelayout or not in android? -

-

hi friends have 2 framelayout in movies.xml namely container, detail_screen.in container add movies.xml contains listview ,and in detail_screen have expandable listview called movie_details.xml.now want check programatically in detail_screen fragment presented or not.if presented want remove fragment.i did follwing , working fine.

    if (getsupportfragmentmanager().findfragmentbytag("myfragment") != null) {         getsupportfragmentmanager().begintransaction().remove(getsupportfragmentmanager().findfragmentbytag("myfragment")).commit(); }

but there other way find whether fragment presented or not in frame layout in android programatically .thanks in advance

i founded solution follows.i.e before adding fragments details_screen checking if fragment presented popping , add new fragment.

if (getsupportfragmentmanager().findfragmentbyid(r.id.detail_screen) != null) {          getsupportfragmentmanager().popbackstack();              } //to add fragment

hope work.

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...
