Trying to hide and show menu items on action bar

Question

I have looked through the questions on stack overflow and can\'t find the solution.

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    MenuInflater i         


        

Answer 1

I have a menu with two items, first: save item, second: edit item. I wanted when I came in to edit, at first "save item" had been hidden, and when I click "edit item", "save item" was shown.

So:

1. declare an item in public
2. set value to it in onCreateOptionsMenu(Menu menu, MenuInflater inflater)
3. set visibility to isHidden()
4. then every where I wanted, set visibility to isVisible()

Public region:

MenuItem saveItem;

onCreateOptionsMenu:

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.menu_detail_products, menu);
    saveItem = (MenuItem) menu.findItem(R.id.action_detail_product_save);
    saveItem.setVisible(isHidden());
}

Where i want:

saveItem.setVisible(isVisible());

Finally it works as I wanted.
