first - set below xml attributes each target view's parent may blocking animation :

    android:clipchildren="false"     android:cliptopadding="false"

you need set attributes @ 3 places in case.
read more clipchildren & cliptopadding here - http://developer.android.com/reference/android/view/viewgroup.html#attr_android:clipchildren http://developer.android.com/reference/android/view/viewgroup.html#attr_android:cliptopadding

if minsdk >=12
use swap animation :

    findviewbyid(r.id.swap).setonclicklistener(new view.onclicklistener() {         boolean isanimating;         @override         public void onclick(view v) {             if(isanimating)                 return;             isanimating=true;              view v1 = findviewbyid(r.id.swap_above);             view v2 = findviewbyid(r.id.swap_below);             float x1, y1, x2, y2;            x1 = getrelativex(v1);//use v1.getx() if v1 & v2 have same parent            y1 = getrelativey(v1);//use v1.gety() if v1 & v2 have same parent            x2 = getrelativex(v2);//use v2.getx() if v1 & v2 have same parent            y2 = getrelativey(v2);//use v2.gety() if v1 & v2 have same parent              float x_displacement = (x2-x1);             float y_displacement = (y2-y1);              v1.animate().xby(x_displacement).yby(y_displacement);             v2.animate().xby(-x_displacement).yby(-y_displacement);             long anim_duration = v1.animate().getduration();              //wait till animation on set isanimating false             //take 10 ms buffer time ensure proper functioning             //if remove timer & isanimating variable, animation function improperly when user rapidly clicks on swap button             new countdowntimer(anim_duration + 10, anim_duration + 10) {                 @override                 public void ontick(long millisuntilfinished) {                  }                  @override                 public void onfinish() {                     isanimating=false;                 }             }.start();          }          //returns x-pos relative root layout         private float getrelativex(view myview) {             if (myview.getparent() == myview.getrootview())                 return myview.getx();             else                 return myview.getx() + getrelativex((view) myview.getparent());         }          //returns y-pos relative root layout         private float getrelativey(view myview) {             if (myview.getparent() == myview.getrootview())                 return myview.gety();             else                 return myview.gety() + getrelativey((view) myview.getparent());         }     });

read view property animator here - http://developer.android.com/reference/android/view/viewpropertyanimator.html http://developer.android.com/guide/topics/graphics/prop-animation.html

also, should try minimize number of views in layout. read layout optimization here - http://developer.android.com/training/improving-layouts/optimizing-layout.html

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). ...
