android - Disabling (fade in and fade out) dialog box animation -

i'm novice programmist , have problem disabling dialog box animation (fade in , fade out).

i tried to using empty style , set changing

final alertdialog.builder builder = new alertdialog.builder(getactivity()); 

into

final alertdialog.builder builder = new alertdialog.builder(new contextthemewrapper(getactivity(), r.style.noanimation)); 

background of dialog box became black, positive , negatice button changed <2.1 - 4.0) android style, fade in , fade out animation effect remained...

my style:

<style name="dialognoanimation">     <item name="android:windowenteranimation">@anim/enter</item>     <item name="android:windowexitanimation">@anim/exit</item> </style>  <style name="noanimation" parent="@android:style/theme.dialog">     <item name="android:windowanimationstyle">@style/dialognoanimation</item> </style> 

any ideas how can eliminate animation?

finally success!

res/anim/enter.xml

<?xml version="1.0" encoding="utf-8"?> <translate xmlns:android="http://schemas.android.com/apk/res/android"  android:duration="@android:integer/config_shortanimtime"/> 

res/anim/exit.xml

<?xml version="1.0" encoding="utf-8"?> <translate xmlns:android="http://schemas.android.com/apk/res/android"     android:duration="@android:integer/config_shortanimtime"/> 

res/values/styles.xml

<style name="dialognoanimation">     <item name="android:windowenteranimation">@anim/enter</item>     <item name="android:windowexitanimation">@anim/exit</item> </style> 

src/[dialog_box_class].java

@override public void onstart() {   super.onstart();   if (getdialog() == null)     return;   getdialog().getwindow().setwindowanimations(r.style.dialognoanimation); }
