Android - Activity that does not fill the parent screen

Question

Any idea why this doesn\'t create an activity that looks like a popup instead of an activity that completely fills the screen?

Answer 1

You must set your Activity's window to be floating. You can do this either by giving your activity the Dialog style defined by Android (android:style/Theme.Dialog), or define your own style, like this:

<style name="MyFloatingWindow">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowNoTitle">true</item>
</style>

Then set the style on your activity in the application's Manifest.

On my phone but check this website here it shows how to use PopupWindow correctly.

Hope this helps or points you in the right direction.
