# ActionBar added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) belongs to Maven artifact com.android.support:appcompat-v7:28.0.0-alpha1 Summary:[Nested Classes](https://developer.android.com/reference/android/support/v7/app/ActionBar#nestedclasses)\|[Constants](https://developer.android.com/reference/android/support/v7/app/ActionBar#constants)\|[Ctors](https://developer.android.com/reference/android/support/v7/app/ActionBar#pubctors)\|[Methods](https://developer.android.com/reference/android/support/v7/app/ActionBar#pubmethods)\|[Inherited Methods](https://developer.android.com/reference/android/support/v7/app/ActionBar#inhmethods)\|[\[Expand All\]](https://developer.android.com/reference/android/support/v7/app/ActionBar#) # ActionBar | This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). ` public abstract class ActionBar ` ` extends Object `` ` |---|----------------------------------| | java.lang.Object || | ↳ | android.support.v7.app.ActionBar |
*** ** * ** *** A primary toolbar within the activity that may display the activity title, application-level navigation affordances, and other interactive items. The action bar appears at the top of an activity's window when the activity uses the AppCompat's[AppCompat](https://developer.android.com/reference/android/support/v7/appcompat/R.style#Theme_AppCompat)theme (or one of its descendant themes). You may otherwise add the action bar by calling[requestFeature(FEATURE_SUPPORT_ACTION_BAR)](https://developer.android.com/reference/android/support/v7/app/AppCompatDelegate#requestWindowFeature(int))or by declaring it in a custom theme with the[windowActionBar](https://developer.android.com/reference/android/support/v7/appcompat/R.styleable#AppCompatTheme_windowActionBar)property. The action bar may be represented by any Toolbar widget within the application layout. The application may signal to the Activity which Toolbar should be treated as the Activity's action bar. Activities that use this feature should use one of the supplied`.NoActionBar`themes, set the[windowActionBar](https://developer.android.com/reference/android/support/v7/appcompat/R.styleable#AppCompatTheme_windowActionBar)attribute to`false`or otherwise not request the window feature. If your activity has an options menu, you can make select items accessible directly from the action bar as "action items". You can also modify various characteristics of the action bar or remove it completely. The navigation button (formerly "Home") takes over the space previously occupied by the application icon. Apps wishing to express a stronger branding should use their brand colors heavily in the action bar and other application chrome or use a[logo](https://developer.android.com/reference/android/support/v7/app/ActionBar#setLogo(int))in place of their standard title text. From your activity, you can retrieve an instance of[ActionBar](https://developer.android.com/reference/android/support/v7/app/ActionBar)by calling[getSupportActionBar()](https://developer.android.com/reference/android/support/v7/app/AppCompatActivity#getSupportActionBar())getSupportActionBar()}. In some cases, the action bar may be overlayed by another bar that enables contextual actions, using an[ActionMode](https://developer.android.com/reference/android/support/v7/view/ActionMode). For example, when the user selects one or more items in your activity, you can enable an action mode that offers actions specific to the selected items, with a UI that temporarily replaces the action bar. Although the UI may occupy the same space, the[ActionMode](https://developer.android.com/reference/android/support/v7/view/ActionMode)APIs are distinct and independent from those for[ActionBar](https://developer.android.com/reference/android/support/v7/app/ActionBar). ### Developer Guides For information about how to use the action bar, including how to add action items, navigation modes and more, read the[Action Bar](https://developer.android.com/guide/topics/ui/actionbar)developer guide.

Set this flag if selecting the 'home' button in the action bar to return up by a single level in your UI rather than back to the top level or front page. Setting this option will implicitly enable interaction with the home/up button.

If enabled, the action bar will scroll out of sight along with a[nested scrolling child](https://developer.android.com/reference/android/view/View.html#setNestedScrollingEnabled(boolean))view's content. The action bar must be in[overlay mode](https://developer.android.com/reference/android/view/Window.html#FEATURE_ACTION_BAR_OVERLAY)to enable hiding on content scroll.

Examples of this are, "Navigate Home" or "Navigate Up" depending on the[DISPLAY_HOME_AS_UP](https://developer.android.com/reference/android/support/v7/app/ActionBar#DISPLAY_HOME_AS_UP)display option. If you have changed the home-as-up indicator using[setHomeAsUpIndicator(int)](https://developer.android.com/reference/android/support/v7/app/ActionBar#setHomeAsUpIndicator(int))to indicate more specific functionality such as a sliding drawer, you should also set this to accurately describe the action. Setting this to`null`will use the system default description.

| Parameters || |---------------|-------------------------------------------------------------------------| | `description` | `CharSequence`: New description for the Home action when enabled
| **See also:** - [setHomeAsUpIndicator(int)](https://developer.android.com/reference/android/support/v7/app/ActionBar#setHomeAsUpIndicator(int)) - [setHomeAsUpIndicator(android.graphics.drawable.Drawable)](https://developer.android.com/reference/android/support/v7/app/ActionBar#setHomeAsUpIndicator(android.graphics.drawable.Drawable)) ### setHomeActionContentDescription added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void setHomeActionContentDescription (int resId) ``` Set an alternate description for the Home/Up action, when enabled.
