xamarin.android - Navigation Drawer back button Xamarin -

i using binding awesome material drawer library mikepenz.

i have implemented navigation drawer library , have managed change hamburger menu arrow when go level deep. have problems arrow work correctly. when click on arrow, rather going previous page, opens navigation drawer.

after looking original library, have identified, following code responsible manage arrow button. appreciate , if can me bit write listener code in c#.

.withondrawernavigationlistener(new drawer.ondrawernavigationlistener() {                 @override                 public boolean onnavigationclicklistener(view clickedview) {                     //this method called if arrow icon shown. hamburger automatically managed materialdrawer                     //if arrow shown. close activity                     advancedactivity.this.finish();                     //return true if have consumed event                     return true;                 }             }) 

here binding libray use : materialdrawer-xamarin

and link original library : materialdrawer

try this:

var result = new drawerbuilder()         .withactivity(this)         .adddraweritems(           //add items here           new dividerdraweritem()         )         .withondrawernavigationlistener(this); 

and implement drawer.iondrawernavigationlistener in activity this:

public bool onnavigationclicklistener(view clickedview) {     this.finish();     return true; }
