android - Gridview image to give sqlite data -

-

i have been trying find can me retrieve sqlite database row when click on gridview image ! when click first image on new activity shows me data related image saved in database. 

@override public void onclick(view v) {   // todo auto-generated method stub   intent intent = new intent(mcontext,herodata.class);   intent.putextra("imageid", mthumbids[position]);   mcontext.startactivity(intent); }

this how i'm starting new activity , putting image click, need know how sql database row has data related image.

public cursor gettestdata()   {       try       {           string sql ="select * heroes";            cursor mcur = mdb.rawquery(sql, null);           if (mcur!=null)           {              mcur.movetonext();           }           return mcur;       }       catch (sqlexception msqlexception)        {           log.e(tag, "gettestdata >>"+ msqlexception.tostring());           throw msqlexception;       }   }

the above cursor data, want 1 row.

you can pass image position next activity... , after pass image position select query related data of image displayed...

so try this:

string sqlstring ="select * heroes id = "+position;

(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...
