ListView selected item highlight

Question

I'm working on a GridView with setChoiceMode(GridView.CHOICE_MODE_MULTIPLE_MODAL). By default, rows are not getting highlighted (with the blue highlight you see on WhatsApp or Gallery apps), so I am wondering, does the Android API already takes care of highlighting the selected items and I am missing something (if so, what am I missing?) or do I have to take care of highlighting selected rows by myself (if so, how to highlight, not just change the background)?

Here's my code:

gridView.setOnItemClickListener(this);
gridView.setEmptyView(view.findViewById(R.id.empty));
gridView.setChoiceMode(GridView.CHOICE_MODE_MULTIPLE_MODAL);

// multiChoiceModeListener is a subclass of AbsListView.MultiChoiceModeListener
// with no particular code on its abstracts methods.
gridView.setMultiChoiceModeListener(multiChoiceModeListener);

Use this for your ListItem background (XML layout)

android:background="?android:attr/activatedBackgroundIndicator"

It's basically only a selector, you can also build yourself: https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/drawable/activated_background.xml

EDIT:

Given your comment, this solves it:

android:foreground="?android:attr/activatedBackgroundIndicator" with a FrameLayout

do you mean to the row layout itself? – Christopher Francisco May 21 '14 at 14:21
yep, your row/item/entry layout – einschnaehkeee May 21 '14 at 14:25
it works but since my cells are images that covers the entire cell, they background can't be seen. Any ideas? – Christopher Francisco May 21 '14 at 14:56
You can use the Android Gallery App as an inspiration how to do an indicator or a ImageView selection: https://android.googlesource.com/platform/packages/apps/Gallery/+/master – einschnaehkeee May 21 '14 at 15:03
oh didn't know it was opensourced – Christopher Francisco May 21 '14 at 15:05
using `foreground` instead of `background` but **only** on `FrameLayout` solved it. I'll give you the answer cause that resource is what I was looking for. Please update your answer to specify it works on framelayout with foreground attr. – Christopher Francisco May 21 '14 at 15:25
