How to make an Activity transparent over another Activity?

  <style name="Theme.CustomTranslucent" parent="android:style/Theme.Translucent">
        <item name="android:backgroundDimEnabled">true</item>
        <item name="android:backgroundDimAmount">0.5</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:background">@android:color/transparent</item>
 </style>  

In my activity 2 layout, I could eihter set android:background="@android:color/transparent" or not set any value at all to make it work.

Incase of AppcompatActivity:

<style name="Theme.AppCompat.Translucent">

    <item name="android:windowNoTitle">true</item>

    <item name="android:windowBackground">@android:color/transparent</item>

    <item name="android:colorBackgroundCacheHint">@null</item>

    <item name="android:windowIsTranslucent">true</item>

    <item name="android:windowAnimationStyle">@android:style/Animation</item>

</style>

Add the following line in <activity> in AndroidManifest.xml

android:theme="@style/Theme.CustomTranslucent"
