User · Answer

On my Galaxy S4 having   441dpi   1080 x 1920    Getting Actionbar height with getResources   getDimensionPixelSize I got 144 pixels   Using formula px   dp x  dpi 160   I was using 441dpi  whereas my device lies   in the category 480dpi  so putting that confirms the result

AZ13 s answer is good  but as per the Android design guidelines  the ActionBar should be at least 48dp high

To retrieve the height of the ActionBar in XML  just use   android attr actionBarSize   or if you re an ActionBarSherlock or AppCompat user  use this   attr actionBarSize   If you need this value at runtime  use this  final TypedArray styledAttributes   getContext   getTheme   obtainStyledAttributes                      new int     android R attr actionBarSize     mActionBarSize    int  styledAttributes getDimension 0  0   styledAttributes recycle      If you need to understand where this is defined    The attribute name itself is defined in the platform s  res values attrs xml The platform s themes xml picks this attribute and assigns a value to it  The value assigned in step 2 depends on different device sizes  which are defined in various dimens xml files in the platform  ie  core res res values-sw600dp dimens xml

The Class Summary is usually a good place to start  I think the getHeight   method should suffice    EDIT   If you need the width  it should be the width of the screen  right   and that can be gathered like this

With the new v7 support library  21 0 0  the name in R dimen has changed to  dimen abc action bar default height material   When upgrading from a previous version of the support lib you should therefore use that value as the actionbar s height

I needed to do replicate these heights properly in a pre-ICS compatibility app and dug into the framework core source  Both answers above are sort of correct   It basically boils down to using qualifiers  The height is defined by the dimension  action bar default height   It is defined to 48dip for default  But for -land it is 40dip and for sw600dp it is 56dip

User · Answer

To get the actual height of the Actionbar  you have to resolve the attribute actionBarSize at runtime    TypedValue tv   new TypedValue    context getTheme   resolveAttribute android R attr actionBarSize  tv  true   int actionBarHeight   getResources   getDimensionPixelSize tv resourceId

One of the Honeycomb samples refers to  android attr actionBarSize
