android - Search widget doesn't integrate with toolbar, when calling onSearchRequested() -

-

i created xml file in menu folder search item.

<item android:id="@+id/action_search"     android:title="@string/search_hint"     android:icon="@drawable/ic_magnify_white_24dp"     app:showasaction="collapseactionview|ifroom"     app:actionviewclass="android.support.v7.widget.searchview"     />

i setup menu search function

@override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu items use in action bar         menuinflater inflater = getmenuinflater();         inflater.inflate(r.menu.menu_option, menu);          // associate searchable configuration searchview         searchmanager searchmanager =                 (searchmanager) this.getsystemservice(context.search_service);         searchview searchview =                 (searchview) menu.finditem(r.id.action_search).getactionview();         searchview.setsearchableinfo(                 searchmanager.getsearchableinfo(getcomponentname()));          return super.oncreateoptionsmenu(menu);     }      @override     public boolean onoptionsitemselected(menuitem item) {         // handle presses on action bar items         switch (item.getitemid()) {             case r.id.action_search:                 //start search activity here                 onsearchrequested();                 return true;             default:                 return super.onoptionsitemselected(item);         }     }

the problem when i'm calling onsearchrequested(), search widget not integrate toolbar. see image: enter image description here should (and when i'm not calling onsearchrequested(). thought documentation says, onsearchrequested needs called?): enter image description here search widget loads twice. enter image description here

any appreciated. thanks!

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
