Android - How to hide menu option for current fragment

Question

I have an ActionBar activity with a FrameLayout and a menu. when the user clicks the menu item I replace the fragment with the relevant new fragment. However, I cannot see a

Answer 1

In the fragment where you want to hide the Item

@Override
public void onPrepareOptionsMenu(Menu menu) {
    MenuItem item=menu.findItem(R.id.action_search);
    item.setVisible(false);

and in onCreate() of your fragment

 setHasOptionsMenu(true);

Answer 2

Add below codes into your fragment

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
}

public void onPrepareOptionsMenu(Menu menu) {
    super.onPrepareOptionsMenu(menu);
    MenuItem item = menu.findItem(R.id.save);
    item.setVisible(false);
}

Answer 3

First get the item you want to remove :

MenuItem item = menu.findItem(R.id.your_action);

then set it's Visibility false :

item.setVisible(false);

and if the problem is in getting the menu (as it's not in the fragment), you can easily get a context from the activity that contains the menu and get the menu by it.

Answer 4

Inside your fragment you will have to use setHasOptionsMenu(true); in order to access options menu from within your fragment.

Code (inside your second fragment where you wanna hide the item):

@Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setHasOptionsMenu(true);
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
  // TODO your code to hide item here
  super.onCreateOptionsMenu(menu, inflater);     
}

Similarly, for your fragment where you want to show that MenuItem you can do the similar thing.

Answer 5

// create Boolean variable in the main activity
private var menuvisibile:  Boolean = true

// while navigating fragments set the menuvisibile value and use it 
// variable as part of the return statement
invalidateOptionsMenu()
menuvisibile = false

override fun onCreateOptionsMenu(menu: Menu?): Boolean 
    {
        val menuInflater  = menuInflater
        menuInflater.inflate(R.menu.notification,menu)
        return menuvisibile
    }

working well for me.

Answer 6

Adding to Muhammed's answer above. Once the item has been set as invisible, you may need to also disable the item. Note Google's comment: "Even if a menu item is not visible, it may still be invoked via its shortcut (to completely disable an item, set it to invisible and disabled)" under setVisible() in the MenuItem documentation. Thus:

• item.setVisible(false);
• item.setEnabled (false);
