android - How to make NavigationView header sticky -

is possible make header sticky in design support library navigationview?

<android.support.design.widget.navigationview     android:id="@+id/nav_drawer"     android:layout_width="wrap_content"     android:layout_height="match_parent"     android:layout_gravity="start"     app:headerlayout="@layout/nav_header"     app:menu="@menu/nav_drawer"     style="@style/navigation_view_drawer"     />

edit:

my attempts far have led this

overriding navigationview widget , adding new method:

public class customnavigationview extends navigationview {  public customnavigationview(context context) {     super(context); }   public customnavigationview(context context, attributeset attrs) {     super(context, attrs); }   public customnavigationview(context context, attributeset attrs, int defstyle) {     super(context, attrs, defstyle); }   // inflates header child of navigationview, on top of normal menu public void createheader(int res) {     layoutinflater inflater = layoutinflater.from(getcontext());;     view view = inflater.inflate(res, this, false);     addview(view); } 

}

then adding oncreate of activity:

customnavigationview navigationview = (customnavigationview) findviewbyid(r.id.your_navigation_view); navigationview.createheader(r.layout.your_header); 

this achieves desired effect (if bit hackily) when menu items below header can still click them, ideas fix this?

after lots of experimenting i've got works...it's hacky , i'd love hear suggestions have improve it!

the overrided navigationview

public class customnavigationview extends navigationview {  public customnavigationview(context context) {     super(context); }   public customnavigationview(context context, attributeset attrs) {     super(context, attrs); }   public customnavigationview(context context, attributeset attrs, int defstyle) {     super(context, attrs, defstyle); }   // consumes touch in navigationview doesn't propagate views below public boolean ontouchevent (motionevent me) {     return true; }   // inflates header child of navigationview public void createheader(int res) {     layoutinflater inflater = layoutinflater.from(getcontext());     view view = inflater.inflate(res, this, false);      // consumes touch in header doesn't propagate menu items below     view.setontouchlistener(new ontouchlistener() {         @override         public boolean ontouch(view v, motionevent event){             return true;         }     });      addview(view); }   // positions , sizes menu view public void sizemenu(view view) {     // height of header     int header_height = (int) getresources().getdimension(r.dimen.nav_header_height);      // gets required display metrics     displaymetrics displaymetrics = getresources().getdisplaymetrics();     float screen_height = displaymetrics.heightpixels;      // height of menu     int menu_height = (int) (screen_height - header_height);      // layout params menu     layoutparams params = new layoutparams(             layoutparams.match_parent,             layoutparams.wrap_content);     params.gravity = gravity.bottom;     params.height = menu_height;     view.setlayoutparams(params); } 

}

and in oncreate of main activity

// inflates nav drawer     customnavigationview navigationview = (customnavigationview) findviewbyid(r.id.your_nav_view);     navigationview.createheader(r.layout.your_nav_header);      // sizes nav drawer menu appears under header     viewgroup parent = (viewgroup) navigationview;     view view = parent.getchildat(0);     navigationview.sizemenu(view);
