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().

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
