Android No resource matches android:windowIsFloating

I am trying to make my activity as popup / floating activity after watching this video

https://www.youtube.com/watch?v=fn5OlqQuOCk

But I want to make window background Semi Translucent. So I added windowIsFloating -> true

<style name="AppTheme.NamTheme">
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowCloseOnTouchOutside">true</item>
</style>

But getting following error

Error:(2374, 21) No resource found that matches the given name: attr 'android:windowIsFloating'.

Solution

  • Add a parent android theme to your custom theme. For example,

    <style name="AppTheme.NamTheme" parent="android:Theme.Light.NoTitleBar">
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowCloseOnTouchOutside">true</item>
</style>
