android - Should we replace Action Bar by ToolBar? -


i have been using toolbar since added support v7 library. , think used well. there point can't understand. why google create such widget? mean can toolbar can using actionbar. why have use toolbar? advantages of toolbar on actionbar if any? necessary replace actionbar toolbar?

any tips appreciated. , in advance.

ps: found toolbar decandant of viewgroup. so, how use toolbar layout? post codes of that?

yes should replace actionbar new toolbar

reasons

1) looks modern , follows new material design

2) unlike action bar , toolbar not part of window decor.you defines , place other widget...therefor have freedom place anywhere in parent layout.

3) have freedom put widget inside toolbar.

4) can define multiple toolbars.

edit

what meant can place other widgets(views) inside toolbar.

create separate layout file toolbar(good reusability).in case file name main_toolbar . 

    <?xml version="1.0" encoding="utf-8"?>     <android.support.v7.widget.toolbar         xmlns:android="http://schemas.android.com/apk/res/android"         xmlns:tools="http://schemas.android.com/tools"         xmlns:app="http://schemas.android.com/apk/res-auto"         xmlns:segmentedgroup="http://schemas.android.com/apk/res-auto"         android:id="@+id/toolbar"         android:layout_width="match_parent"         app:theme="@style/toolbarcoloredbackarrow"         android:layout_height="56dp"         android:background="@color/primary_color" >         <textview             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:textsize="@dimen/drawer_fntsize"             android:text="title"             android:id="@+id/lbl_title"             android:textcolor="@color/title_text_color"             android:layout_gravity="center" />      </android.support.v7.widget.toolbar>

then include toolbar in main layout this

<relativelayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent">  <include     android:id="@+id/toolbar"     layout="@layout/main_toolbar"/>   <framelayout     android:id="@+id/content_frame"      android:layout_width="match_parent"     android:layout_height="match_parent"     android:layout_below="@+id/toolbar" />

as can see in example placed textview inside toolbar

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
