android custom view obtainStyledAttributes -


i'm pretty new android , java forgive me if i'm missing obvious.

i want write custom view, , have problems getting custom attributes via otainstyledattributes. have simple testcase. in eclipse create empty project (package com.example.customview) default activity. added "attrs.xml" file under res/values following content:

  <resources>     <declare-styleable name="testview">        <attr name="test" format="string"/>     </declare-styleable>   </resources>

then add new class "testview.java" in new package "com.example.views".

package com.example.views;  import android.content.context; import android.content.res.typedarray; import android.util.attributeset; import android.widget.linearlayout; import android.widget.textview;  import com.example.customview.r;  public class testview extends linearlayout{    public testview(context context,attributeset attrs){     super(context,attrs);      textview tv = new textview(context);     this.addview(tv);     typedarray = context.gettheme().obtainstyledattributes(attrs, r.styleable.testview, 0, 0);      tv.settext(a.getstring(r.styleable.testview_test));      a.recycle();  } }

and in activity_main.xml have:

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     xmlns:my="http://schemas.android.com/apk/res/com.example.customview"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingbottom="@dimen/activity_vertical_margin"     android:paddingleft="@dimen/activity_horizontal_margin"     android:paddingright="@dimen/activity_horizontal_margin"     android:paddingtop="@dimen/activity_vertical_margin"     tools:context=".mainactivity" >      <com.example.views.testview         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="@string/hello_world"          my:test="test"         />  </relativelayout>

i able my:test attribute 

attrs.getattributevalue("http://schemas.android.com/apk/res/com.example.customview","test")

but works if put attribute in random namespace.

but a.getstring(r.styleable.testview_test) allways null.

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).
