android - Support Contextual Action Bar never inflates -
in order add contextual action bar application using support action bar v7 library implemented :
my actionbaractivity (support v7) :
package com.supinfo.cubbyhole.mobileapp.activities; import com.supinfo.cubbyhole.mobileapp.r; import android.os.bundle; import android.support.v7.app.actionbaractivity; import android.support.v7.view.actionmode; import android.view.menu; import android.view.menuinflater; import android.view.menuitem; import android.view.view; import android.widget.adapterview; import android.widget.arrayadapter; import android.widget.listview; public class homy extends actionbaractivity { private actionmode mactionmode; private listview list; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_home); // instantiate , fill list custom adapter ... fine list = (listview) findviewbyid(r.id.home_list); string[] array = {"test", "test2", "test3"}; list.setadapter(new arrayadapter<string>(this, android.r.layout.simple_list_item_1, android.r.id.text1, array)); list.setonitemlongclicklistener(new adapterview.onitemlongclicklistener() { @override public boolean onitemlongclick(adapterview<?> adapterview, view view, int position, long l) { if (mactionmode != null) { return false; } mactionmode = startsupportactionmode(mactionmodecallback); view.setselected(true); return true; } }); } private actionmode.callback mactionmodecallback = new actionmode.callback() { @override public boolean oncreateactionmode(actionmode mode, menu menu) { // inflate menu resource providing context menu items menuinflater inflater = mode.getmenuinflater(); inflater.inflate(r.menu.menu, menu); return true; } // called each time action mode shown. called after oncreateactionmode, // may called multiple times if mode invalidated. @override public boolean onprepareactionmode(actionmode mode, menu menu) { return false; // return false if nothing done } // called when user selects contextual menu item @override public boolean onactionitemclicked(actionmode mode, menuitem item) { switch (item.getitemid()) { case r.id.action_settings: mode.finish(); // action picked, close cab return true; default: return false; } } // called when user exits action mode @override public void ondestroyactionmode(actionmode mode) { mactionmode = null; } }; } my contextual_menu.xml :
<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/test" android:icon="@android:drawable/ic_menu_delete" android:showasaction="ifroom|withtext" android:title="@string/test" android:titlecondensed="delete"> </item> </menu> and when try long click on item got stack error :

-- edit --
issue due override of close icon in auto generated theme... had comment line :
<item name="android:actionmodeclosebuttonstyle">@style/actionbutton.closemode.cubbyhole</item>
the exception stack overflow (how appropriate) while expanding "close" icon in cab. because of state-list drawable references itself.
the relevant code in actionbarcontextview.java is:
layoutinflater inflater = layoutinflater.from(mcontext); mclose = inflater.inflate(r.layout.action_mode_close_item, this, false); the problem might related incorrect definition of actionmodeclosedrawable drawable, or actionmodeclosebuttonstyle style.
is either 1 of them customized in theme, possibly recursive state-list drawable?
in case correctly defined, suggest cleaning , rebuilding project (the resource ids may incorrect).
