android - How to navigate to Activity from Sliding panel when the back button is pressed -

i have fragment activity sliding panel in it. implemented following exit app when user presses button.

@override     public void onbackpressed() {         //this close , exit app         intent intent = new intent(intent.action_main);         intent.addcategory(intent.category_home);         intent.setflags(intent.flag_activity_clear_top);//***change here***         startactivity(intent);         finish();         system.exit(0);     } 

however, stay in same activity if the user on sliding panel , wants navigate activity. right if user presses button when sliding panel displayed, closes app. how accomplish that?

hope using slidingpanellayout

mslidingpanellayout = (slidingpanelayout) findviewbyid(r.id.label); 

then

public void onbackpressed() {     if(mslidingpanellayout.isopen())     {         mslidingpanellayout.closepane();     }     else      {         //closeactivity();     } } 

you can use panelslidelistener

    mslidingpanellayout.setpanelslidelistener(new slidingpanelayout.panelslidelistener() {         @override         public void onpanelslide(view panel, float slideoffset) {          }          @override         public void onpanelopened(view panel) {          }          @override         public void onpanelclosed(view panel) {          }     });
