Android ViewDrawer homebutton -

i'm trying create viewdrawer support-lib actionbaractivity. layout looks

<?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_container" android:layout_width="match_parent" android:layout_height="match_parent" > <framelayout android:id="@+id/content" android:layout_width="match_parent" android:layout_height="match_parent" /> <include android:id="@+id/drawer_view" android:layout_width="@dimen/drawer_width" android:layout_height="match_parent" android:layout_gravity="start" layout="@layout/include_drawer" /> </android.support.v4.widget.drawerlayout>

and activity looks this:

public abstract class baseactivity extends basesimpleactivity { public static final string fragment_tag = "content"; protected drawerlayout mdrawerlayout; protected actionbardrawertoggle mdrawertoggle; protected listview mdrawerlist; protected viewgroup mdrawerview; protected view mdrawerbtnsettings; private handler mhandler; @override protected void oncreate(bundle savedinstancestate) { ... } protected void initviews(string title, fragment fragment) { setcontentview(r.layout.activity_base_secondary); getsupportfragmentmanager().begintransaction().replace(r.id.content, fragment, fragment_tag).commit(); initdrawer(); initactionbar(); } protected void settitle(string title) { super.settitle(title); getsupportactionbar().settitle(title); } private void initactionbar() { android.support.v7.app.actionbar actionbar = getsupportactionbar(); actionbar.setdisplayoptions(actionbar.display_home_as_up); //actionbar.seticon(r.drawable.ic_launcher); actionbar.setdisplayshowtitleenabled(false); actionbar.setdisplayshowcustomenabled(true); actionbar.setcustomview(r.layout.action_bar); textview title = (textview) actionbar.getcustomview().findviewbyid(r.id.actionbartitle); title.settext(gettitleresid()); title.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v) { if (mdrawerlayout.isdraweropen(gravity.start)) { mdrawerlayout.closedrawers(); } else { mdrawerlayout.opendrawer(gravity.start); } } }); refreshactionbar(); } public abstract string gettitleresid(); private void initdrawer() { mdrawerlayout = (drawerlayout) findviewbyid(r.id.drawer_container); mdrawerview = (viewgroup) findviewbyid(r.id.drawer_view); mdrawerlist = (listview) findviewbyid(r.id.drawer_list); mdrawerlist.setadapter(new drawerlistadapter(this)); mdrawerlist.setonitemclicklistener(new draweritemclicklistener()); mdrawertoggle = createdrawertoggle(); mdrawerlayout.setdrawerlistener(mdrawertoggle); mdrawerbtnsettings = findviewbyid(r.id.drawer_settings); refreshdrawer(); } private actionbardrawertoggle createdrawertoggle() { homecoming new actionbardrawertoggle(this, mdrawerlayout, r.drawable.ic_drawer, r.string.drawer_open, r.string.drawer_close); } @override public boolean onprepareoptionsmenu(menu menu) { refreshactionbar(); int size = menu.size(); mmenuitemids = new int[size]; (int = 0; < size; i++) { mmenuitemids[i] = menu.getitem(i).getitemid(); } homecoming super.onprepareoptionsmenu(menu); } @override public boolean onoptionsitemselected(menuitem item) { if (mdrawertoggle.onoptionsitemselected(item)) { homecoming true; } homecoming super.onoptionsitemselected(item); } @override protected void onpostcreate(bundle savedinstancestate) { super.onpostcreate(savedinstancestate); mdrawertoggle.syncstate(); } @override public void onconfigurationchanged(configuration newconfig) { super.onconfigurationchanged(newconfig); mdrawertoggle.onconfigurationchanged(newconfig); } protected boolean isdraweropen() { homecoming mdrawerlayout.isdraweropen(mdrawerview); } /** * update title , invalidate options menu */ protected void refreshactionbar() { if (isdraweropen()) { setactionbaritemsalpha(0); } else { getsupportactionbar().settitle(gettitle()); } } /** * update selected item. */ protected void refreshdrawer() { navigation id = navigation.getid(this); if(id != null) { mdrawerlist.setitemchecked(id.ordinal(), true); } } protected void ondraweritemclick(int which) { // override if subclass needs hear drawer click events } private class draweritemclicklistener implements listview.onitemclicklistener { @override public void onitemclick(adapterview<?> parent, view view, int position, long id) { selectdraweritem(position); } } protected void selectdraweritem(final int which) { navigation id = navigation.getid(this); if (id != null && == id.ordinal()) { return; } ondraweritemclick(which); mpendinglaunch = drawerutils.buildlaunchrunnable(this, which); mdrawerlayout.closedrawer(mdrawerview); } }

but can see on screenshot below icon drawer rendered on devices , on others not rendered @ all. when check in android monitor layout has width of zero. clues on whats going on?

if using v21 of appcompat, need utilize android.support.v7.app.actionbardrawertoggle rather deprecated v4 version using.
