Android imitates iphone list Data View Refresh animation detailed _android

Because I personally like to jump between different pages to add some fun animation, today accidentally saw an animation effect feel good, several effect chart is as follows: Since the fun is written in the blog, directly said: The effect is similar to the iphone view of the switch animation effect, today is only to introduce the effect of the above show.

Nonsense not to say, first on the effect, and then look at the code!!

Effect One:

Effect Two:

Effect Three:

Effect Four: (The effect of error):

Effect Five (Swing effect one):

Effect VI (Maneuver Effect II):

The effect is finished, just look at the implementation of the above effect of the specific code, the middle will be my own test, make mistakes are written down in the form of annotations, we use the time not to go wrong on the line! First look at the layout of the use of the file, very simple layout:

xml/html Code

<?xml version= "1.0" encoding= "Utf-8"?> <linearlayout xmlns:android= 
"http://schemas.android.com/apk/" Res/android " 
 android:layout_width=" fill_parent " 
 android:layout_height=" fill_parent " 
 android:o" rientation= "vertical" > 
 <listview 
 android:id= "@+id/firstpage" android:layout_width= "Fill_" 
 Parent " 
 android:layout_weight=" 1.0 " 
 android:layout_height=" 0dip "/> 
 <listview 
 android: Id= "@+id/secondpage" 
 android:layout_width= "fill_parent" 
 android:layout_weight= "1.0" 
 android: layout_height= "0dip" 
 android:visibility= "Gone"/> 
 <button android:id= 
 "@+id/startnext" 
 android:layout_width= "fill_parent" 
 android:layout_height= "wrap_content" 
 android:text= "@string Next " 
 
 /> 
 

xml/html Code

<strong> below to see the implementation of the above effect of the specific code, the order in the code and the above display of the effect of the picture consistent:</strong>

  This place records, the following this listener pony first met, check the official document explained as follows: This monitoring to monitor the life cycle of the animation such as: Start, end, playing, follow/loop playback, here, remember: animation is not to monitor the animation, it is only responsible for the animation Vistoinvis.addlistener (New Animatorlisteneradapter () {@Override public void Onanimationend (animator Anim) {/

Finally, again, the title of the article is said to be a paging animation, in fact, these animations are not limited to the page above, if you put the interpolation, animation with a little flexibility, you can also make a very personalized with a lot of animation applications, coupled with the animation between the activity and above these combined words are more perfect , the activity between the animation you can refer to my previous writing this article (link below), I hope to help.
