How to get the ActionBar height

Question

I am trying to get the height of the ActionBar  using Sherlock  every time an activity is created  specially to handle configuration changes on rotation where the ActionBar height might change    For this I use the method ActionBar getHeight   which works only when the ActionBar is shown   When the first activity is created for the first time  I can call getHeight   in the onCreateOptionsMenu callback  But this method is not called after   So my question is when can I call getHeight   and be assured that it doesn t return 0  Or if it is not possible  how can I set the height of the ActionBar

i think the safest way would be    private int getActionBarHeight         int actionBarHeight   getSupportActionBar   getHeight        if  actionBarHeight    0          return actionBarHeight      final TypedValue tv   new TypedValue        if  Build VERSION SDK INT  gt   Build VERSION CODES HONEYCOMB            if  getTheme   resolveAttribute android R attr actionBarSize  tv  true               actionBarHeight   TypedValue complexToDimensionPixelSize tv data  getResources   getDisplayMetrics           else if  getTheme   resolveAttribute com actionbarsherlock R attr actionBarSize  tv  true           actionBarHeight   TypedValue complexToDimensionPixelSize tv data  getResources   getDisplayMetrics         return actionBarHeight

While  birdy s answer is an option if you want to explicitly control the ActionBar size  there is a way to pull it up without locking the size that I found in support documentation   It s a little awkward but it s worked for me   You ll need a context  this example would be valid in an Activity      Calculate ActionBar height TypedValue tv   new TypedValue    if  getTheme   resolveAttribute android R attr actionBarSize  tv  true         Int actionBarHeight   TypedValue complexToDimensionPixelSize tv data getResources   getDisplayMetrics         Kotlin   val tv   TypedValue   if  requireActivity   theme resolveAttribute android R attr actionBarSize  tv  true         val actionBarHeight   TypedValue complexToDimensionPixelSize tv data  resources displayMetrics

The action bar now enhanced to app bar So you have to add conditional check for getting height of action bar   if  Build VERSION SDK INT  gt   Build VERSION CODES HONEYCOMB       height   getActivity   getActionBar   getHeight       else     height     ActionBarActivity  getActivity    getSupportActionBar   getHeight

Anthony answer works for devices that support ActionBar and for those devices which support only Sherlock Action Bar following method must be used      TypedValue tv   new TypedValue        if  getTheme   resolveAttribute android R attr actionBarSize  tv  true           actionBarHeight   TypedValue complexToDimensionPixelSize tv data getResources   getDisplayMetrics          if actionBarHeight   0  amp  amp  getTheme   resolveAttribute com actionbarsherlock R attr actionBarSize  tv  true                actionBarHeight   TypedValue complexToDimensionPixelSize tv data getResources   getDisplayMetrics                 OR as stated by  Marina Eariel    TypedValue tv   new TypedValue       if Build VERSION SDK INT gt  Build VERSION CODES HONEYCOMB         if  getTheme   resolveAttribute android R attr actionBarSize  tv  true           actionBarHeight   TypedValue complexToDimensionPixelSize tv data getResources   getDisplayMetrics         else if getTheme   resolveAttribute com actionbarsherlock R attr actionBarSize  tv  true           actionBarHeight   TypedValue complexToDimensionPixelSize tv data getResources   getDisplayMetrics

To set the height of ActionBar you can create new Theme like this one    lt  xml version  1 0  encoding  utf-8   gt   lt resources gt          lt style name  Theme FixedSize  parent  Theme Sherlock Light DarkActionBar  gt           lt item name  actionBarSize  gt 48dip lt  item gt           lt item name  android actionBarSize  gt 48dip lt  item gt        lt  style gt     lt  resources gt    and set this Theme to your Activity   android theme   style Theme FixedSize

A simple way to find actionbar height is from Activity onPrepareOptionMenu method    Override public boolean onPrepareOptionsMenu Menu menu                               int actionBarHeight   getActionBar   getHeight

In xml  you can use  attr actionBarSize  but if you need access to that value in Java you need to use below code   public int getActionBarHeight             int actionBarHeight   0          TypedValue tv   new TypedValue            if  Build VERSION SDK INT  gt   Build VERSION CODES HONEYCOMB                if  getTheme   resolveAttribute android R attr actionBarSize  tv                      true                   actionBarHeight   TypedValue complexToDimensionPixelSize                          tv data  getResources   getDisplayMetrics               else               actionBarHeight   TypedValue complexToDimensionPixelSize tv data                      getResources   getDisplayMetrics                       return actionBarHeight

Ok I was googling around and get to this post several times so I think it ll be good to be described not only for Sherlock but for appcompat also   Action Bar height using appCompat  Pretty similiar to  Anthony description you could find it with following code I ve just changed resource id    TypedValue tv   new TypedValue     if  getActivity   getTheme   resolveAttribute R attr actionBarSize  tv  true         int actionBarHeight   TypedValue complexToDimensionPixelSize tv data getResources   getDisplayMetrics         Pre Sandwitch Problem  I needed action bar height because on pre ICE CREAM SANDWITCH devices my view was overlaping action bar  I tried setting android layout marginTop   android attr actionBarSize   android layout marginTop   attr actionBarSize   setting overlap off to view actionbar and even fixed actionbar height with custom theme but nothing worked  That s how it looked     Unfortunately I found out that with method described above I get only half of the height I assume that options bar is not taken in place  so to completely fix the isue I need to double action bar height and everything seems ok     If someone knows better solution than doubling actionBarHeight  I ll be glad to let me know as I come from iOS development and I found most of Android view s stuff pretty confusing     Regards   hris to

The action bar height differs according to the applied theme  If you re using AppCompatActivity the height will be different in most of cases from the normal Activity   If you re using AppCompatActivity you should use R attr actionBarSize instead of android R attr actionBarSize  public static int getActionBarHeight Activity activity            TypedValue typedValue   new TypedValue             int attributeResourceId   android R attr actionBarSize          if  activity instanceof AppCompatActivity                attributeResourceId   R attr actionBarSize                     if  activity getTheme   resolveAttribute attributeResourceId  typedValue  true                 return TypedValue complexToDimensionPixelSize typedValue data  activity getResources   getDisplayMetrics                        return  int  Math floor activity getResources                    getDimension R dimen my default value

I found a more generic way to discover it     int   location   new int 2     mainView getLocationOnScreen location     int toolbarHeight   location 1     where  mainView  is the root view of your layout   The idea is basically get the Y position of the mainView as it is set right below the ActionBar  or Toolbar

If you are using a Toolbar as the ActionBar   Toolbar toolbar    Toolbar  findViewById R id toolbar   setSupportActionBar toolbar     then just use the layout height of the toolbar   int actionBarHeight   toolbar getLayoutParams   height

you just have to add this        public int getActionBarHeight             int height           if  Build VERSION SDK INT  gt   Build VERSION CODES HONEYCOMB                height   getActivity   getActionBar   getHeight              else               height     ActionBarActivity  getActivity    getSupportActionBar   getHeight                       return height
