Cannot catch toolbar home button click event

Question

I\'ve implemented the newest appcompat library and using the Toolbar as action bar. But the problem is I cannot catch the home button / hamburger icon click eve

Answer 1

The easiest approach we could do is change the home icon to a known icon and compare drawables (because android.R.id.home icon can differ to different api versions

so set a toolbar as actionbar SetSupportActionBar(_toolbar);

_toolbar.NavigationIcon = your_known_drawable_here;

   for (int i = 0; i < _toolbar.ChildCount; i++)
            {
                View v = _toolbar.GetChildAt(i);
                if (v is ImageButton)
                {
                    ImageButton imageButton = v as ImageButton;

                    if (imageButton.Drawable.GetConstantState().Equals(_bookMarkIcon.GetConstantState()))
                    {
                       //here v is the widget that contains the home  icon you can add your click events here 
                    }
                }
            }
