while I'm able to set "highlight color" for ListView items using android:listSelector
attribute and appropriate selector, I'm unable to do the same, or something similar,
for Menu items - they just keep using default system color scheme. I've read Creating Menus article and found nothing there. Any clues?
Btw: I'm referring to Menu accessible via 'Menu' button.

I am working on an Android application where I have to design a menu which will populate from the action bar, like this:
I have tried my best but was not able to produce it using the Android controls.
The solutions I have tried are:
With Actionbar, add a menu item with a group with selectable="all", that produces the layout I need but when I click a checkbox for selecting it, the whole menu hides and selection is not done, moreover the menu icon in actionbar does not have the bottom right white arrow.
Tried creating a custom ActionProvider and added the menu items using class's OnPrepareSubMenu method but had the same issue.
I just need a push in the right direction and I can do the rest, suggestions are more than welcome.
Thank you :)
Use popupWindow.
In that you can make any custom layout and set it as content of your popupwindow and also you can specify an ANCHOR in your case it would be
R.id.your_menu_item
set a listener and listen the changes.
I've used the action bar style generator to generate a custom action bar theme for an app, and it works well after a few tweaks. My custom theme is based on Holo (the dark version) and changes the highlight colours. My action bar overflow menu correctly shows my custom state_pressed colour on the overflow items when I press them. I've set android:colorPressedHighlight to the colour I want, and put an appropriate drawable for android:selectableItemBackground.
The problem is on one of my test devices, which has a hard menu button. (It's a Samsung Galaxy S III.) When I show the overflow menu with the hard menu button, pressing an item from this menu gives it the default blue highlight. Either it uses another attr instead of android:selectableItemBackground, or it's taking it from another style. I'd like to know what attr it's using, or what style it's taking it from, so that I can set this colour.
P.S. Before anyone suggests it, I know that you can use android:panelBackground to set the background of the bottom menu. But I don't want to change the overall menu background, only the item background.
How can I change item selector for hardkey menu? I was able to set custom item selector for actionbar menu. Unfortunately some devices with hardkey menu(like Nexus S) create different menu style. I want to replace default blue highlight selector with my custom red. I searched topics here and elsewhere without success. ICS+ compatibility is enough.
I was wondering if it were at all possible to have checkable icons in an action bar in ICS? Not with a check, but with a android:stateChecked property to play around with. I want it so when the user clicks on the icon, they enter a certain mode (and the background of the icon would be a bright color to let them know they are still in that mode), and when they click it again they are taken out of that mode. I've played around with some selector xmls but nothing has worked...Any ideas?
EDIT: I just learned that Checkable items cannot appear in main menus, they can only be in submenus. However, is there a way to still get the behavior of a checkable? It's easy enough to have a boolean like isInModeA, but is there a way to programmatically change the background/icon of an Action bar item?
There is a way to programmatically change the background/icon.
You can use ActionBar.setBackgroundDrawable, for instance, or setCustomView, or setIcon (found on the same page).
You may consider using a dropdown-like ActionProvider to provide e.g. a radio-button-like "on/off" rather than a checkbox.
One approach you could try is to keep the state saved in some variable and just display different items based on this state. Obviously, some of these items can change the state. You might look at doing this by implementing a custom action provider.
I want to change the menu item background beacuse I use black icons, but on some phones the default color of background is black or other dark color. I tried this solution and it's worked but there was a little problen with it:
I have ten items and that's why I have a "More" item to show other options, but if I choose the More item (which is got the custom background) and after that I press back button, the item will be in the default state, default colors. What is the solution? Thanks!
The style attribute for the menu background is android:panelFullBackground. It's not hackish like the other solution, so it's not as buggy.
Despite what the documentation says, it needs to be a resource (e.g. #android:color/black or #drawable/my_drawable), it will crash if you use a color value directly.
try to use android own menu icon like as setIcon(android.R.drawable.ic_menu_search)
