android - How to add ActionBar to an activity which already extends ListActivity? -

i have activity extends listactivity.
can add actionbar without extending actionbaractivity?

you can use new appcompatdelegate component provided support library.

actionbar deprecated , should use toolbar, compliant material design. can use toolbar provided support library.

add xml layout this:

<android.support.v7.widget.toolbar          android:id="@+id/my_awesome_toolbar"         android:layout_height="wrap_content"         android:layout_width="match_parent"         android:minheight="56dp"         android:background="?attr/colorprimary"          /> 

be sure use noactionbar theme in styles.xml. use material design color tags.

<style name="apptheme" parent="theme.appcompat.noactionbar"> </style> 

then, add appcompatdelegate activity, in oncreate(), this.

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      appcompatcallback callback = new appcompatcallback() {         @override         public void onsupportactionmodestarted(actionmode actionmode) {         }          @override         public void onsupportactionmodefinished(actionmode actionmode) {         }     };      appcompatdelegate delegate = appcompatdelegate.create(this,callback);      delegate.oncreate(savedinstancestate);     delegate.setcontentview(r.layout.activity_main);      toolbar toolbar= (toolbar) findviewbyid(r.id.my_awesome_toolbar);     delegate.setsupportactionbar(toolbar);   } 

note: create appcompatdelegate need pass activity , callback, practice should implementing callback in activity, shortening reasons created instance in oncreate().
