问题
I want to be able to specify a custom view for a MenuItem.
I want to display an indicator on a shopping cart menu item in the action bar displaying how many items are in the cart currently.
Is the only way that I can do this is through adding a custom view instead of utilising the MenuItem lifecycle etc.?
回答1:
To use a custom view on a MenuItem call setActionView(View view).
You can supply either an already inflated view or a layout resource ID.
