Android invalidateOptionsMenu() for API < 11

android menu
SnitramSD picture SnitramSD · Dec 23, 2012 · Viewed 20.4k times · Source

I used ActivityCompat.invalidateOptionsMenu(MainActivity.this); so that my menu item "refresh" can automatically be enabled/disabled without the using have to touch the "Menu" option (imagine the user leaves the Menu open... I need the "Refresh" menu item to automatically disabled and enable itself).

The ActivityCompat.invalidateOptionsMenu(MainActivity.this) works fine in Android 11+. But what can I use for android API < 11 ? :S I've searched so much but I cannot find an answer. Can anyone please help me on this?

This works fine in Android API 11+, using the onPrepareOptionsMenu and ActivityCompat.invalidateOptionsMenu(MainActivity.this). The issue is trying to get it done in Android API < 11.

Here is my onPrepareOptionsMenu method: 

@Override
public boolean onPrepareOptionsMenu(Menu menu) {
    if(menuRefreshEnable){
        menu.getItem(0).setEnabled(true);
    }
    if(!menuRefreshEnable){
        menu.getItem(0).setEnabled(false);
    }       
    return true;
}
