Menu
There's a question for the same functionality on Blackberry, and a few different threads referred to this bug (which has since been closed without resolution as far as I can tell), but I haven't found one specifically for Android.
I'm calling setEnabled(false) on certain MenuItems based on some state, but they visually look the same. I'd like them to be offset in some way, so that the user knows that the option currently isn't available -- is there any way to do that?

To disable a menu item, set its Enabled property to False. In the following example, an event handler is attached to the OnClick event for the Edit item on a child form's menu bar. It sets Enabled for the Cut, Copy, and Delete menu items on the Edit menu based on whether RichEdit1 has selected text.
To enable and disable menu items, use the MenuItem class's setEnabled method.
A context menu is a floating menu that appears when the user performs a long-click on an element. It provides actions that affect the selected content or context frame.
On all android versions, easiest way to use this to SHOW a menu action icon as disabled AND make it FUNCTION as disabled as well:
@Override public boolean onPrepareOptionsMenu(Menu menu) { MenuItem item = menu.findItem(R.id.menu_my_item); if (myItemShouldBeEnabled) { item.setEnabled(true); item.getIcon().setAlpha(255); } else { // disabled item.setEnabled(false); item.getIcon().setAlpha(130); } } If you love us?
