Why android navigation drawer creating two headers? -
i followed tutorial push facebook info login activity navigation, put on top, shown, which, after days of altering code, got work. cant original header go away. i've tried changing every part of code, end or nothing. know 2 heads better one, exception rule.
also, guess cant post images, so, original header on top, should be. new header facebook profile picture , info, underneath that. , below that, starts navigation drawer menu.

when add header using app:headerlayout="@layout/nav_header_home" below
<android.support.design.widget.navigationview android:id="@+id/nav_view" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" android:fitssystemwindows="true" app:headerlayout="@layout/nav_header_home" app:menu="@menu/activity_home_drawer" /> then no need add header again code
remove below lines setnavigationheader() method
navigation_view.removeheaderview(null); view header = layoutinflater.from(this).inflate(r.layout.nav_header_home, null); navigation_view.addheaderview(header); after remove method below
edit /
public void setnavigationheader(){ navigation_view = (navigationview) findviewbyid(r.id.nav_view); view header = layoutinflater.from(this).inflate(r.layout.nav_header_home, null);
user_name = (textview) navigation_view.findviewbyid(r.id.username); user_picture = (imageview) navigation_view.findviewbyid(r.id.profile_pic); user_email = (textview) navigation_view. findviewbyid(r.id.email); }
