I think you have to do as follow

<ul>
<li>Set "in" and "out" animations</li>
<li>Create folder res/anim</li>
<li>Put animation descriptions into res/anim folder 

<code>object.setInAnimation(AnimationUtils.loadAnimation(this, R.anim.zoom_enter));
 object.setOutAnimation(AnimationUtils.loadAnimation(this, R.anim.zoom_exit));</code></li>
</ul>

You can use android sdk sample animations supplied by google under Apache 2.0 licence

Or refer this which uses scaling based zooming which is easier than the former

blocks|key|3006421|text|您可以在运行命令后使用此方法来启动新的活动。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3006422|startActivity(intent);
overridePendingTransition(animation_in_goes_here,animation_out_goes_here);|code-block|syntax|javascript|3006423|然后，您可以替换上面的动画，将animation_in_goes_here替换为新启动的活动所需的动画资源，并将animation_out_goes_here替换为要离开的活动的动画资源。这将为您提供切换效果。|offset|length|style|CODE|3006424|zoom_in.xml|BOLD|3006425|<?xml+version="1.0"+encoding="utf-8"?>

You can use this method after running the command to start your new activity, 

<pre class="lang-java prettyprint-override"><code>startActivity(intent);
overridePendingTransition(animation_in_goes_here,animation_out_goes_here);
</code></pre>

Then you may replace your animations above, replacing the <code>animation_in_goes_here</code> with the animation resource you need for the activity that you have newly started and replacing <code>animation_out_goes_here</code> with the animation resource for the activity that you are leaving from. This will give you the switching effects.

I have code of normally zoom in and zoom out animation between two activities, but I want something different. I have five buttons on my first activity if I click on first button then zoom in would be starts from position of first button only instead of zooming from centre. Please help me.

EDIT : Zoom should start from the button I clicked as a centre.

zoom in and zoom out animation in android

我有两个活动之间正常放大和缩小动画的代码，但我想要一些不同的东西。我的第一个活动有五个按钮，如果我点击第一个按钮，那么放大将只从第一个按钮的位置开始，而不是从中心开始。请帮帮我。编辑:缩放应该从我点击的按钮开始作为中心。
