android - navigation drawer does not show main layout when app start -
my navigation drawer works perfect every time run program drawer opened default instead of main layout. navigation drawer should opened when clicked on drawer button.
public class mainactivity extends activity { private drawerlayout mdrawerlayout; private listview mdrawerlist; private actionbardrawertoggle mdrawertoggle; private charsequence mdrawertitle; private charsequence mtitle; customdraweradapter adapter; list<draweritem> datalist; @suppresslint("newapi") @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); // initializing datalist = new arraylist<draweritem>(); mtitle = mdrawertitle = gettitle(); mdrawerlayout = (drawerlayout) findviewbyid(r.id.drawer_layout); mdrawerlist = (listview) findviewbyid(r.id.left_drawer); mdrawerlayout.setdrawershadow(r.drawable.drawer_shadow, gravitycompat.start); // add drawer item datalist // add drawer item datalist datalist.add(new draweritem("message", r.drawable.ic_action_email)); datalist.add(new draweritem("likes", r.drawable.ic_action_good)); datalist.add(new draweritem("games", r.drawable.ic_action_gamepad)); datalist.add(new draweritem("lables", r.drawable.ic_action_labels)); datalist.add(new draweritem("search", r.drawable.ic_action_search)); datalist.add(new draweritem("cloud", r.drawable.ic_action_cloud)); datalist.add(new draweritem("camara", r.drawable.ic_action_camera)); datalist.add(new draweritem("video", r.drawable.ic_action_video)); datalist.add(new draweritem("groups", r.drawable.ic_action_group)); datalist.add(new draweritem("import & export", r.drawable.ic_action_import_export)); datalist.add(new draweritem("about", r.drawable.ic_action_about)); datalist.add(new draweritem("settings", r.drawable.ic_action_settings)); datalist.add(new draweritem("help", r.drawable.ic_action_help));

a post made couple of days ago appears use same nav drawer template. there, problem solved removing these lines of code:
if (savedinstancestate == null) { selectitem(0); } as first item in list being automatically selected. try deleting section , see happens. this post referring well.
