Displaying activity with custom animation

Question

I have a widget which starts an activity when it is clicked. I'd like to have some kind of fancy animation to display this activity, rather than the standard scroll-from-right of Android. I'm having problems setting it, though. This is what I have:

slide_top_to_bottom.xml

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" android:interpolator="@android:anim/accelerate_interpolator">     <translate android:fromYDelta="-100%" android:toXDelta="0" android:duration="100" />     <alpha android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="50" /> </set> 

...which is referenced in anim.xml

<?xml version="1.0" encoding="utf-8"?> <layoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"         android:delay="50%"         android:animation="@anim/slide_top_to_bottom" /> 

But then where do I reference it from? I've tried both the base element of the activity I want to slide in, and the activitiy's entry in the manifest, both times with

android:layoutAnimation="@+anim/anim" 

I might be doing this all wrong. Any help is much appreciated!

Answer 1

You can create a custom Theme with a reference to your own animation and apply it to your Activity in your manifest file. I was successful in applying a custom animation for a floating window using the following style definition. You might be able to do something similar if you set the parent of your style to be "@android:style/Animation.Activity"

Look at the following files for further details on what you can override.

https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/themes.xml

Here's my a portion of my styles.xml and manifest.xml

styles.xml

<style name="MyTheme" parent="@android:style/Theme.Panel">     <item name="android:windowNoTitle">true</item>     <item name="android:backgroundDimEnabled">true</item>     <item name="android:windowAnimationStyle">@style/MyAnimation.Window</item> </style>  <!-- Animations -->  <style name="MyAnimation" />   <!-- Animations for a non-full-screen window or activity. -->  <style name="MyAnimation.Window" parent="@android:style/Animation.Dialog">      <item name="android:windowEnterAnimation">@anim/grow_from_middle</item>     <item name="android:windowExitAnimation">@anim/shrink_to_middle</item> </style>  

Manifest.xml

    <activity         android:name="com.me.activity.MyActivity"         android:label="@string/display_name"         android:theme="@style/MyTheme">     </activity> 

Answer 2

startActivity(intent); overridePendingTransition(R.anim.slide_top_to_bottom, R.anim.hold); 

Check this link: overridePendingTransition method

Edit:

To Achieve the Animation for the Views. You have use the startAnimation Method like below

view.startAnimation(AnimationUtils.loadAnimation(                  WidgetActivity.this,R.anim.slide_top_to_bottom));
