android - (How Should I) embed map 2.0 inside a ribbon that user can expand? -

-

i want display google map api 2.0 inside ribbon above data ui fragment , give user possibility expand map interact it. illustration: ribbon , expanded

doing so, user has map illustrate position when in ribbon mode while when user ewpands map (covering 4/5 of screen) can use map features.

how should ? though on it?

i thinking about

  • a sliding drawer top contains map
  • an overlaying "card ui" interface display data on map,
  • trying mess heigh , focus (but that's way done screenshots , user interaction cries improvement)

any advice?

thank ideas , looking @ !

disclaimer: know ios-like transforming toward native design, application uses actionbarcompat needed show wanted result ( , not current state).

this how did if need it:

  • i define linearlayout intercept user action , control map extension/shrinking.
  • i put mapfragment v2.0 inside relative layout.
  • i define scroll view dimensions when expanding shrinking map.

layout fragment: 

    <?xml version="1.0" encoding="utf-8"?> <com.snapcar.rider.utils.lineartoucheventlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:pj="http://schemas.android.com/apk/res/com.snapcar.rider"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:background="@drawable/bg_red"     android:orientation="vertical" >      <relativelayout         android:id="@+id/map_fragment_container"         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_weight="1" >     </relativelayout>      <scrollview         android:id="@+id/scrollview1"         style="@style/sc_scroll_view"         android:layout_width="match_parent"         android:layout_height="0dp"         android:layout_weight="5" >  layout content      </scrollview> </com.snapcar.rider.utils.lineartoucheventlayout>

            return true;         } else { //          dbg.d(tag, "point out side view");             return false;         }     }   }

and @ least useful method in fragment class:

the oncreate callback: 

@override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {      dbg.v(tag, "- oncreateview bookingformfragment");     root = inflater.inflate(r.layout.fragment_booking_form, null);     root.setonclicklistener(this);      mscroll = (scrollview) root.findviewbyid(r.id.scrollview1);      /*      * map fragment      */     fragmentmanager fm = getchildfragmentmanager();     mapfragment = new custommapfragment();     fm.begintransaction().replace(r.id.map_fragment_container, mapfragment).commit(); things need set menu item , scroll content }

the shrink/expand method :

private void shrinkmap() {  dbg.d(tag, "shrinkmap");  dropdownanim anim = new dropdownanim(mscroll, false); anim.setduration(300); anim.setanimationlistener(new animationlistener() {      @override     public void onanimationstart(animation animation) {         dbg.d(tag, "dropdownanim - shrink start");         isshrinking = true;     }      @override     public void onanimationrepeat(animation animation) {     }      @override     public void onanimationend(animation animation) {         dbg.d(tag, "dropdownanim shrink end");         isshrinking = false;         ismapshrinked = true;         adjustmapposandzoom();     } });  getview().startanimation(anim); }

and of course animation definition : 

private class dropdownanim extends animation { boolean down; float maxratio = 5; float minratio =  0.2f;  public dropdownanim(view view, boolean down) {     this.down = down; }  @override protected void applytransformation(float interpolatedtime, transformation t) {     float currentratio;     if (down) {         currentratio = maxratio - (float) ((maxratio - minratio) * interpolatedtime);     } else {         currentratio = minratio + (float) ((maxratio - minratio) * interpolatedtime);     }     linearlayout.layoutparams param2 = new linearlayout.layoutparams(             layoutparams.match_parent,             0, (float) currentratio);     dbg.d(tag, "---   "+ currentratio);     mscroll.setlayoutparams(param2);     root.requestlayout(); }  @override public void initialize(int width, int height, int parentwidth, int parentheight) {     super.initialize(width, height, parentwidth, parentheight); }  @override public boolean willchangebounds() {     return true; } }

python - TypeError: can only concatenate tuple (not "float") to tuple -

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...
