java - findViewByIdlayoutinflator fails to inflate my layouts, returns null when using -


my main activity calls view inflate main.xml whatever reason seems return null, i'm kind of lost here since worked in 4.2 doesn't after upgrading rest of source 6.0

    @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      layoutinflater inflater = (layoutinflater) this.getsystemservice(             context.layout_inflater_service);      view layout = inflater.inflate(r.layout.main, null);      setcontentview(layout);      ctx = this;      prefs = preferencemanager.getdefaultsharedpreferences(this);     res = getresources();      maudiomanager = (audiomanager)getsystemservice(context.audio_service);      mmediabuttonreceiver = new remotecontrolreceiver();     mediafilter = new intentfilter(intent.action_media_button);     mediafilter.setpriority(integer.max_value);      registerreceiver(mmediabuttonreceiver, mediafilter);      //mdrawable = (this.res.getdrawable(r.drawable.glowy_metal));     //mbackground.setbackgrounddrawable(mdrawable);     mbackground = (imageview) layout.findviewbyid(r.id.background);     mbackground.setontouchlistener(new backgroundtouchlistener());

logcat shows null here:

mbackground = (imageview) layout.findviewbyid(r.id.background);

the background id in main.xml

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="vertical">     <imageview         android:id="@+id/background"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:layout_alignparentleft="true"         android:layout_alignparenttop="true"         android:scaletype="fitcenter"         android:background="@drawable/glowy_metal"/>

can shed insight might going on here?

logcat :

just use

setcontentview(r.layout.main);

and later

mbackground = (imageview) findviewbyid(r.id.background);

no need create new inflater since activity has methods want.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
