android - Custom (gradient) background of ActionBar Compat -

-

i using action bar compat action bar navigation drawer backward compatible down api level 9 , want change background of action bar.

i copied code android developers:

<?xml version="1.0" encoding="utf-8"?> <resources> <!-- theme applied application or activity --> <style name="customactionbartheme"        parent="@style/theme.appcompat.light.darkactionbar">     <item name="android:actionbarstyle">@style/myactionbar</item>      <!-- support library compatibility -->     <item name="actionbarstyle">@style/myactionbar</item> </style>  <!-- actionbar styles --> <style name="myactionbar"        parent="@style/widget.appcompat.light.actionbar.solid.inverse">     <item name="android:background">@drawable/actionbar_background</item>      <!-- support library compatibility -->     <item name="background">@drawable/actionbar_background</item> </style> </resources>

and here comes problem.

when put image drawable or color background, works fine. want define background gradient shape, actionbar_background looks like:

<?xml version="1.0" encoding="utf-8"?> <shape     xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="line"> <gradient         android:startcolor="@color/ac_bg_start"         android:endcolor="@color/ac_bg_end"         android:type="linear"/> <size         android:width="1dp"         android:height="48dp"/> </shape>

i want repeated in horizontal way results in error, in fact, interesting error. test device , emulator gets restarted when try run app. able catch deadobjectexception before restarting.

how should background drawable like?

i working on same task.

here action_bar_bg.xml file in define gradient action bar.

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android">     <gradient         android:angle="90"         android:centercolor="@color/turquoise_action_bar"         android:endcolor="@color/dark_turquoise"         android:startcolor="@color/dark_turquoise" /> </shape>

deadobjectexception

android:shape="line" can't used if there gradient inside. tested it; samsung galaxy note 10.1 n8000 restarted, , there deadobjectexception.

the linear type of gradient pattern default value. don't have declare explicitly.

here styles.xml in values folder.

<resources>      <!-- base application theme. -->     <style name="appthemebase" parent="theme.appcompat.light.darkactionbar">         <item name="android:actionbarstyle">@style/peoplecanact</item>         <!-- support library compatibility -->         <item name="actionbarstyle">@style/myactionbar</item>     </style>      <style name="apptheme" parent="appthemebase">         <!-- customizations not specific particular api level can go here -->     </style>      <!-- actionbar styles -->     <style name="myactionbar" parent="@style/widget.appcompat.light.actionbar.solid.inverse">         <item name="android:background">@drawable/action_bar_bg</item>         <!-- support library compatibility -->         <item name="background">@drawable/action_bar_bg</item>     </style>  </resources>

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...
