How to hide an optionsmenu button at runtime

Question

In my app i have an optionsmenu. It has 2 buttons. Depending on a boolean value i would like to show/hide one of the buttons. I've got the following code but it doesn't hide the button. How can i do this?

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.layout.menushowmoredetails, menu);
        return true;

    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        if(displayRotaDetails.equalsIgnoreCase("false")){
            if(item.getItemId() == R.id.moredetails)
            item.setVisible(false);
            }

        switch (item.getItemId()) {

    case R.id.back:

        onBackPressed();

        return true;

    case R.id.moredetails:

You have to use the onPrepareOptionMenu method like this:

@Override
 public boolean onPrepareOptionsMenu(Menu menu) {
    super.onPrepareOptionsMenu(menu);

// add your conditions here and change 0 with the R.id.moredetails item postion.
if(displayRotaDetails.equalsIgnoreCase("false")){
menu.getItem(1).setVisible(false);
}
}

Hi Anis, Which am i using onOptionsMenuClosed or onPrepareOptionMenu? – turtleboy Oct 24 '12 at 14:05
i've tried onOptionsMenuClosed(Menu menu) but the button does not hide. I've used menu.getItem(1).setVisible(false); as the button is the second in the menu – turtleboy Oct 24 '12 at 14:06
Sorry you have to use onPrepareOptionsMenu. – Anis BEN NSIR Oct 24 '12 at 14:08
PS: you have to insure that the menu item is shown if you want to make it visible. – Anis BEN NSIR Oct 24 '12 at 14:13
