Can I dim the background using a PopupWindow instead of a Dialog? I am asking this because I am using Dialogs but the Dialog doesn't show below the item clicked and with the PopupWindow I already have the popup showing below the item.

It seems that I figured out how to get rid of API version checks. Using container = popupWindow.getContentView().getRootView() solves the problem, however I haven't tested it for old APIs yet. Adapting Junyue Cao's solution:

public static void dimBehind(PopupWindow popupWindow) {
    View container = popupWindow.getContentView().getRootView();
    Context context = popupWindow.getContentView().getContext();
    WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
    WindowManager.LayoutParams p = (WindowManager.LayoutParams) container.getLayoutParams();
    p.flags |= WindowManager.LayoutParams.FLAG_DIM_BEHIND;
    p.dimAmount = 0.3f;
    wm.updateViewLayout(container, p);
}
