-

i'm new in android. i'm having problem right now. app crashes when starting 3rd activity

here code

package com.example.anagramgame;  import android.app.activity; import android.os.bundle; import android.database.cursor; import android.widget.toast;    public class level_list extends activity{      @override     public void oncreate(bundle savedinstancestate)     {         super.oncreate(savedinstancestate);         setcontentview(r.layout.level_list);          dbadapter db = new dbadapter(this);          db.open();         cursor c = db.getallquestions();         if(c.movetofirst())         {                         {                 displaytitle(c);             }while (c.movetonext());         }         db.close();     }      public void displaytitle(cursor c)     {         toast.maketext(this,                          "id: " + c.getstring(0) + "\n" +                         "answer: " + c.getstring(1) + "\n" +                         "question: " + c.getstring(2) + "\n" +                         "hint: " + c.getstring(3) + "\n" +                         "flag: " + c.getstring(4) + "\n" +                         "level:" + c.getstring(5), toast.length_long).show();     } }

and here xml

<?xml version="1.0" encoding="utf-8"?> <scrollview xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" >  <tablelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/tablelayout1"     android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:background="@drawable/background" >       <tablerow         android:id="@+id/tablerow1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:padding="5dip"          android:gravity="left">              <imagebutton                      android:id="@+id/home_button"                     android:background="@drawable/home_button"                     android:layout_width="45dip"                     android:layout_height="50dip"                      />       </tablerow>  </tablelayout>  </scrollview>

and lastly android manifest

    <?xml version="1.0" encoding="utf-8"?>     <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.anagramgame"     android:versioncode="1"     android:versionname="1.0" >      <uses-sdk         android:minsdkversion="10"         android:targetsdkversion="14" />      <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <activity             android:name="com.example.anagramgame.main"             android:configchanges="orientation|keyboardhidden|screensize"             android:label="@string/app_name"             android:theme="@style/fullscreentheme" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>         <activity android:name="stage"></activity>         <activity android:name="level_list"></activity>      </application>  </manifest>

on logcat it's writen "message: failed load file project anagramgame. plugin: com.android.ide.eclipse.adt"

anyone know whats wrong this?

looks issue in manifest can define activity , see if resolves issue : 

            android:theme="@style/theme.transparent" >             <intent-filter>                 <action android:name="com.example.anagramgame.level_list" />                   android:theme="@style/fullscreentheme"                 <category android:name="android.intent.category.default" />             </intent-filter>         </activity>

when call 3rd activity put intent name "com.example.anagramgame.level_list"

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

-
there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey?
