   private void setdate(view c_c) {     // todo auto-generated method stub      final dialog dialog = new dialog(getparent());     dialog.setcontentview(r.layout.date_picker);     dialog.settitle("select date");     datepicker calendarview = (datepicker) dialog.findviewbyid(r.id.date_picker_datepicker);      try {         log.d("***enc_date****",utility.getcurrentdate()+"*******"+utility.convertstringtomilli(utility.getcurrentdate()));         calendarview.setmindate(utility.convertstringtomilli(utility.convertstringformat(commonobjects.patientsdtoencounter.getepisodedate())));         calendarview.setmaxdate(utility.convertstringtomilli(utility.getcurrentdate()));     } catch (exception e) {         e.printstacktrace();     }     button button = (button) dialog.findviewbyid(r.id.btn_cancel_datepicker);      button.setonclicklistener(new onclicklistener() {          public void onclick(view v) {              dialog.dismiss();         }       });      button = (button) dialog.findviewbyid(r.id.btn_set_datepicker);     button.settag(c_c);      // if button clicked, close custom dialog     button.setonclicklistener(new onclicklistener() {         public void onclick(view v) {              dialog.dismiss();         }     });      dialog.show();  }

i had same problem you. in app have fragment extends datepickerdialog , displays on click of button. app chrashed on larger screens there enough space display calendar view of date picker. app, however, calendar view not wanted, , disabling it, app did not crash more when setting both min , max dates.

so, if it's case app don't need calendar view, try disabling calling setcalendarviewshown(false) on date picker instance.

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...
