Android PopupWindow blur or dim background

Question

I would like to be able to either blur or dim the background when I show my popupwindow using popup.showAtLocation, and unblur/dim the background when popup.dismiss is called.

I have tried applying layout params FLAG_BLUR_BEHIND and FLAG_DIM_BEHIND to my activity, and this appears to just blur and dim the background as soon my app is started.

Any suggestions?

You can use android:theme="@android:style/Theme.Dialog" to do that. Create an activity and in your AndroidManifest.xml define the activity as:

    <activity android:name=".activities.YourActivity"
              android:label="@string/your_activity_label"
              android:theme="@android:style/Theme.Dialog">
