自定义ActionBar和溢出菜单

Question

I am implementing custom ActionBar, how should I handle the overflow menu (3 dots icon on the right here: http://developer.android.com/images/ui/actionbar.png )? The overflow menu should be visible if there is no hardware menu button - but how can I detect that?

I'm not using the system ActionBar, because I need a customized behavior.

Answer 1

ViewConfiguration.get(context).hasPermanentMenuKey()

Answer 2

try {
    ViewConfiguration config = ViewConfiguration.get(this);
    Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");


        if (menuKeyField != null) {
            menuKeyField.setAccessible(true);
            menuKeyField.setBoolean(config, false);
        }
    } catch (Exception e) {
        e.printStackTrace();

}

}

Answer 3

The menu button is somewhat outdated , maybe you want to reconsider and stick to the overflow menu? And by the way, do you know http://actionbarsherlock.com/ ?
