How do I hide a menu item in the actionbar?
android, android-actionbar, android-menu, menuitem
Solution
Get a `MenuItem` pointing to such item, call `setVisible` on it to adjust its visibility and then call `invalidateOptionsMenu()` on your activity so the ActionBar menu is adjusted accordingly.
Update: A `MenuItem` is not a regular view that's part of your layout. Its something special, completely different. Your code returns `null` for `item` and that's causing the crash. What you need instead is to do:
MenuItem item = menu.findItem(R.id.addAction);
Here is the sequence in which you should call: first call `invalidateOptionsMenu()` and then inside `onCreateOptionsMenu(Menu)` obtain a reference to the MenuItem (by calling `menu.findItem()`) and call `setVisible()` on it
Problem
I have an action bar with a menuitem. How can I hide/show that menu item? This is what I'm trying to do: ``` MenuItem item = (MenuItem) findViewById(R.id.addAction); item.setVisible(false); this.invalidateOptionsMenu(); ```
