Question

I am creating a menu in android overriding the onCreateOptionsMenu method like so:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    menu.add(0, 0, 0, "Blit").setCheckable(true);
    return true;

}

public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == 0)
    {
              somevar = !somevar;
              item.setchecked(somevar);

            }
    }

The problem is that the menu is never checked … how can i make my menu checked?

Answer 1

You have to update all menu items when onPrepareOptionsMenu is called.

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    for (int i = 0; i < menu.size(); i++) {
        MenuItem item = menu.getItem(i);
        if (item.getItemId() == 0)
            item.setChecked(somevar);
    }
    return super.onPrepareOptionsMenu(menu);
}
