Custom view for Menu Item

Question

I need to have dynamic Menu Item, a circle of user defined color, like this:

Answer 1

What you need to do is create a layout file with the view that you want for the item, the when you declare the item on the menu, assign the layout like this:

And that's it!

EDIT:

To access the custom item and modify it's color at runtime you can do this.

In your activity (or fragment) override the onPrepareOptionsMenu (Assuming you already inflated your menu with 'onCreateOptionsMenu')

@Override
public boolean onPrepareOptionsMenu(Menu menu) {

    //Get a reference to your item by id
    MenuItem item = menu.findItem(R.id.menu_pick_color);

    //Here, you get access to the view of your item, in this case, the layout of the item has a FrameLayout as root view but you can change it to whatever you use
    FrameLayout rootView = (FrameLayout)item.getActionView();

    //Then you access to your control by finding it in the rootView
    YourControlClass control = (YourControlClass) rootView.findViewById(R.id.control_id);

    //And from here you can do whatever you want with your control

    return true;
}
