Using a custom animation, defined in the app/SRC/main/res/values/styles. The XML, all animation for:

 
<style name="popup_window_animation_vertical" parent "=" android: Animation & gt;" 
 
 
</style> 

The animation for push_bottom_in admission, about admission animation code is as follows:

 
<? The XML version="1.0" encoding="utf-8"?> 
Android: duration="300" 
Android: fromYDelta="100% p 
"Android: toYDelta="0"/& gt; 
 

Then I set the animation in the Popupwindow:

 setAnimationStyle (R.s tyle. Popup_window_animation_vertical); 

In constantly tests found that animation is from the bottom up, (if you don't set this animation Popupwindow won't appear the effect of dynamic access, validate my animation effect), but I try to modify the entry in the animation "android: duration", no matter how to modify the ferry the length of the animation didn't actually change the ferry the length of the animation,
