Actions Buttons in Android not visible -

-

i'm working on first android app following official tutorial. right im trying add action buttons

mainactivity:

@override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu items use in action bar     menuinflater inflater = getmenuinflater();     inflater.inflate(r.menu.main_activity_actions, menu);     return super.oncreateoptionsmenu(menu); }

res/menu/main_activity_actions.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >     <!-- search, should appear action button -->     <item android:id="@+id/action_search"           android:icon="@drawable/ic_action_search"           android:title="@string/action_search"           android:showasaction="ifroom" />     <!-- settings, should in overflow -->     <item android:id="@+id/action_settings"           android:title="@string/action_settings"           android:showasaction="never" /> </menu>

the application running without errors, search button not displayed. ic_action_search icon placed res/drawable-* , action_search/action_settings defined in strings.xml.

am missing something?

edit: androidmanifest.xml

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.example.myfirstapp"     android:versioncode="1"     android:versionname="1.0" >      <uses-sdk         android:minsdkversion="8"         android:targetsdkversion="19" />      <application         android:allowbackup="true"         android:icon="@drawable/ic_launcher"         android:label="@string/app_name"         android:theme="@style/apptheme" >         <activity             android:name="com.example.myfirstapp.mainactivity"             android:label="@string/app_name" >             <intent-filter>                 <action android:name="android.intent.action.main" />                  <category android:name="android.intent.category.launcher" />             </intent-filter>         </activity>         <activity             android:name="com.example.myfirstapp.displaymessageactivity"             android:label="@string/title_activity_display_message"             android:parentactivityname="com.example.myfirstapp.mainactivity" >             <meta-data                 android:name="android.support.parent_activity"                 android:value="com.example.myfirstapp.mainactivity" />         </activity>     </application>  </manifest>

styles.xml

<resources>      <!--         base application theme, dependent on api level. theme replaced         appbasetheme res/values-vxx/styles.xml on newer devices.     -->     <style name="appbasetheme" parent="theme.appcompat.light">         <!--             theme customizations available in newer api levels can go in             res/values-vxx/styles.xml, while customizations related             backward-compatibility can go here.         -->     </style>      <!-- application theme. -->     <style name="apptheme" parent="appbasetheme">         <!-- customizations not specific particular api-level can go here. -->     </style>  </resources>

as per document

if app using support library compatibility on versions low android 2.1, showasaction attribute not available android: namespace. instead attribute provided support library , must define own xml namespace , use namespace attribute prefix. (a custom xml namespace should based on app name, can name want , accessible within scope of file in declare it.) example:

<menu xmlns:android="http://schemas.android.com/apk/res/android"       xmlns:yourapp="http://schemas.android.com/apk/res-auto" >     <item android:id="@+id/action_search"           android:icon="@drawable/ic_action_search"           android:title="@string/action_search"           yourapp:showasaction="ifroom"  />     ... </menu>

you missing custom namespace in main_activity_actions.xml. remove yourapp name of app or anything.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
