java - Keep d-pad focus changes within current fragment -

-

i have android app primary receives input using d-pad (up, down, left, right, ok, back)

the app runs on tv uses fragments separate sections.

i keep directional buttons focusing views in other fragments. , handle directional buttons differently depending on fragment set "current"

what elegant solution this?

also, fragments dynamically changed @ runtime.

when d-pad means of navigation user, such on google tv's, it's not idea stop navigation @ edge of fragment. how solved this, allowing cross-border navigation , laying out elements navigation not awkward , works finding path automatically (after all, there not seem way statically provide next element focus on in each direction, when in fragment).

like i'm looking reference advice on how deal fragments , navigation on google tv.

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...
