android - How to add the back arrow in the action bar? -

-

i wondering how add arrow in action bar. have action bar can add icons @ right hand side , possible center label?

enter image description here

first, you'd have define parent activity 1 you'd display button in. via manifest.

do in androidmanifest.xml somewhere within application tag:

<activity     android:name="com.example.myfirstapp.displaymessageactivity"     android:label="@string/title_activity_display_message"     android:parentactivityname="com.example.myfirstapp.mainactivity" >     <!-- parent activity meta-data support 4.0 , lower -->     <meta-data         android:name="android.support.parent_activity"         android:value="com.example.myfirstapp.mainactivity" /> </activity>

that done, you'd need call on target activity, right within oncreate() method:

getactionbar().setdisplayhomeasupenabled(true);

..or, if happen use appcompat library in project:

getsupportactionbar().setdisplayhomeasupenabled(true);

you can refer official docs navigation here further details.
