Get item of actionbar?

I need to get a reference to an item in my actionbar. I want to access it in onCreate

    int silent_mode = SupportFunctions.getSharedPreferenceInt(getApplicationContext(), getResources().getString(R.string.shared_preferences_name), "silent_mode", 0);
    Item item = // getItem?
    if (silent_mode == 1) {
        item.setIcon(getResources().getDrawable(R.drawable.ic_silent_mode_on));
    }
    else {
        item.setIcon(getResources().getDrawable(R.drawable.ic_silent_mode_off));
    }

Any ideas?

do the work in onCreateOptionsMenu() instead, then it will be accessable:

    @Override
public boolean onCreateOptionsMenu(Menu menu) {

    ...


    MenuItem item = menu.findItem(R.id.YOUR_ID);
    int silent_mode = SupportFunctions.getSharedPreferenceInt(getApplicationContext(), getResources().getString(R.string.shared_preferences_name), "silent_mode", 0);
    if (silent_mode == 1) {
        item.setIcon(getResources().getDrawable(R.drawable.ic_silent_mode_on));
    }
    else {
        item.setIcon(getResources().getDrawable(R.drawable.ic_silent_mode_off));
    }

    return true;

}

In onCreateOptionsMenu(Menu menu) store the reference of the menu in a class-level variable. Like this:

Menu mnMenu;

public boolean onCreateOptionsMenu(Menu menu) {
    ....
    ....
    mnMenu = menu;
    return true;   
}

private void someMethod() {
    int silent_mode = SupportFunctions.getSharedPreferenceInt(getApplicationContext(),   getResources().getString(R.string.shared_preferences_name), "silent_mode", 0);
    MenuItem item = mnMenu.findItem(R.id.action) //R.id.action is the id of your MenuItem
    if (silent_mode == 1) {
        item.setIcon(getResources().getDrawable(R.drawable.ic_silent_mode_on));
    }
    else {
        item.setIcon(getResources().getDrawable(R.drawable.ic_silent_mode_off));
    }
}
