Android PopupWindow elevation does not show shadow

android, android-5.0-lollipop, android-popupwindow

Solution

As answered by an Android developer.

If the inflated view doesn't have a background set, or the popup window itself doesn't have a background set (or has a transparent background) then you won't get a shadow.

which was my case and seems to be yours, since you are not using setBackgroundDrawable.

This worked for me

popupWindow.setBackgroundDrawable(new ColorDrawable(Color.WHITE));

I've opened a new issue suggesting that they update the documentation (https://code.google.com/p/android/issues/detail?id=174919)

Problem

Android PopupWindow does not show shadows when the elevation is set. It appears to support it from the documentation. I am using 5.0 Lollipop. Creating the popup as follows: ``` popupWindow = new PopupWindow(context); popupWindow.setOutsideTouchable(true); popupWindow.setFocusable(true); popupWindow.setElevation(10); popupWindow.setContentView(rootView); popupWindow.showAtLocation(anchorView, Gravity.NO_GRAVITY, xPos, yPos); ```
