How to remove items from contextual action bar android -


i want remove copy, select all , find android contextual action bar , add custom menu items.

enter image description here

this appearing while selecting text on webview. trying add text highlights on webview using js.

in order accomplish want, need create entirely new contextual action bar. done through creating custom actionmode. within webview, create nested class implements actionmode.callback. can use template:

public class customwebview extends webview {      private actionmode.callback mactionmodecallback;      @override     public actionmode startactionmode(actionmode mode) {         // block directly webview source code.         viewparent parent = getparent();         if (parent == null) {             return null;         }          mactionmodecallback = new customactionmodecallback();         return parent.startactionmodeforchild(this, mactionmodecallback);     }      private class customactionmodecallback implements actionmode.callback {         // called when action mode created; startactionmode() called         @override         public boolean oncreateactionmode(actionmode mode, menu menu) {             // inflate menu resource providing context menu items             menuinflater inflater = mode.getmenuinflater();             inflater.inflate(r.menu.context_menu, menu);             return true;         }          // called each time action mode shown.         // called after oncreateactionmode,         // may called multiple times if mode invalidated.         @override         public boolean onprepareactionmode(actionmode mode, menu menu) {             // method called when selection handlebars moved.             return false; // return false if nothing done         }          // called when user selects contextual menu item         @override         public boolean onactionitemclicked(actionmode mode, menuitem item) {              switch (item.getitemid()) {             case r.id.menu_button_1:                 // stuff                 break;             case r.id.menu_button_2:                 // stuff                 break;             default:                 // did not handle action, return false                 // if have implemented case every button,                 // block should never called.                 return false;             }              // if want close cab after              // picking action, call mode.finish().             // if want cab persist until user clears selection             // or clicks "done" button, return true.             mode.finish(); // action picked, close cab             return true;         }          // called when user exits action mode         @override         public void ondestroyactionmode(actionmode mode) {             mode = null;         }     }  }

sure define menu in xml resources. here example go above template:

<!-- context_menu.xml --> <?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" >      <item         android:id="@+id/menu_button_1"         android:icon="@android:drawable/menu_button_1"         android:showasaction="always"         android:title="@string/menu_button_1">     </item>     <item         android:id="@+id/menu_button_2"         android:icon="@drawable/menu_button_2"         android:showasaction="ifroom"         android:title="@string/menu_button_2">     </item>  </menu>

noticed did not explicitly state want replace share , web search. unfortunately, method require implement functionality on own. however, can dig source code (i start in actionmode.java) functions. implement new case in customactionmodecallback.onactionitemclicked (where handle button events), copy/paste functionality source, , add corresponding button in xml file. can use native icon functions: android:icon="@android:drawable/[name_of_desired_icon]

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
