android - Using AnimationFactory.Java outToLeftAnimation -

-

i using method creator of animationfactory.java. can not figure out how implement 2 of these methods.

i slide out 1 fragment , slide in one.

here method trying use:

 * slide animations hide view sliding left.  *  * @param duration animation duration in milliseconds  * @param interpolator interpolator use (pass {@code null} use {@link accelerateinterpolator} interpolator)  * @return slide transition animation  */ public static animation outtoleftanimation(long duration, interpolator interpolator) {     animation outtoleft = new translateanimation(             animation.relative_to_parent,  0.0f, animation.relative_to_parent,  -1.0f,             animation.relative_to_parent,  0.0f, animation.relative_to_parent,   0.0f     );     outtoleft.setduration(duration);     outtoleft.setinterpolator(interpolator==null?new accelerateinterpolator():interpolator);     return outtoleft; }    * slide animations enter view right.  *  * @param duration animation duration in milliseconds  * @param interpolator interpolator use (pass {@code null} use {@link accelerateinterpolator} interpolator)  * @return slide transition animation  */ public static animation infromrightanimation(long duration, interpolator interpolator) {      animation infromright = new translateanimation(             animation.relative_to_parent,  +1.0f, animation.relative_to_parent,  0.0f,             animation.relative_to_parent,  0.0f, animation.relative_to_parent,   0.0f     );     infromright.setduration(duration);     infromright.setinterpolator(interpolator==null?new accelerateinterpolator():interpolator);     return infromright; }

anyone know how use these methods?

thanks.

i have order , ordersearch models. in order list (actionindex) gridview there filtering , sorting. on of columns in order order_total (sum of products in order). i need implement sum of order_total in gridview. if manually counting activedataprovider->getmodels() array_map spend 3 seconds 3000 orders (localhost). don't want miss time. i see 2 ways make faster: create cache every filter , update lifetime (horrible) the interesting can right in ordersearch->search() method $query method. don't understand how can pass in controller. example of code 2nd way: class ordersearch extends order { public $totalsum; public function search($params) { $query = order::find(); $dataprovider = new activedataprovider([ 'query' => $query, ]); $this->load($params); $this->totalsum = $query->sum('order_total'); // works fast return $dataprovider; } } after i...

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
