You can force the toolbar by wrapping title and level right padding which has default left padding for title  Than put background color to the parent of toolbar and that way part which is cut out by wrapping title is in the same color white in my example     lt android support design widget AppBarLayout     android id    id appbar layout      android layout width  match parent      android layout height  wrap content      android background   color white  gt            lt android support v7 widget Toolbar            android id    id toolbar             android layout width  wrap content             android layout height  56dp             android layout gravity  center horizontal             android paddingEnd  15dp             android paddingRight  15dp             android theme   style ThemeOverlay AppCompat ActionBar             app titleTextColor   color black   gt    lt  android support design widget AppBarLayout gt

I had the same problem  and because of the  Home  button added automatically in the toolbar  my text was not exactly entered   I fixed it the dirty way but it works well in my case  I simply added a margin to the right of my TextView to compensate for the home button on the left  Here s my toolbar layout     lt android support v7 widget Toolbar     xmlns android  http   schemas android com apk res android      xmlns app  http   schemas android com apk res-auto      android elevation  1dp      android id    id toolbar      android layout width  match parent      android layout height   attr actionBarSize      app layout collapseMode  pin      android gravity  center      android background   color mainBackgroundColor      android fitsSystemWindows  true   gt        lt com lunabee common utils LunabeeShadowTextView         android id    id title          android layout width  match parent          android layout height  wrap content          android layout marginRight   attr actionBarSize          android gravity  center          style   style navigation toolbar title    gt    lt  android support v7 widget Toolbar gt

if You are Using Toolbar the just Add  android layout gravity  center horizontal   Under the Toolbar Just like this snippet    lt android support design widget AppBarLayout     android layout width  match parent      android layout height  wrap content      android theme   style AppTheme AppBarOverlay  gt        lt android support v7 widget Toolbar         android id    id toolbar          android layout width  match parent          android layout height   attr actionBarSize          android background   color colorPrimary          app popupTheme   style AppTheme PopupOverlay  gt            lt TextView             android id    id tvTitle              android layout width  wrap content              android layout height  wrap content              android layout gravity  center horizontal       Important              android textColor   color whitecolor              android textSize  20sp              android textStyle  bold    gt       lt  android support v7 widget Toolbar gt    lt  android support design widget AppBarLayout gt

It seems there is no way to do this without custom view  You can get the title view   View decor   getWindow   getDecorView    TextView title    TextView  decor findViewById getResources   getIdentifier  action bar title    id    android       But changing of gravity or layout gravity doesn t have an effect   The problem in the ActionBarView  which layout its children by itself so changing of layout params of its children also doesn t have an effect  To see this excecute following code   ViewGroup actionBar    ViewGroup  decor findViewById getResources   getIdentifier  action bar    id    android     View v   actionBar getChildAt 0   ActionBar LayoutParams p   new ActionBar LayoutParams ViewGroup LayoutParams MATCH PARENT  ViewGroup LayoutParams MATCH PARENT   p gravity  Gravity CENTER  v setLayoutParams p   v setBackgroundColor Color BLACK

I think by positioning views on action bar you will reach what you want On action bar s layout when layout params set to match parent it does not match full width that s why I did it programmatically where I succeed By setting width  it works like layout weight  value   we can set our view wherever we want       actionBar   getSupportActionBar         actionBar setDisplayShowCustomEnabled true         LayoutInflater ll    LayoutInflater  activity getSystemService Context LAYOUT INFLATER SERVICE       LinearLayout linearLayout    LinearLayout  ll inflate R layout custom actionbar  null         inner layout within above linear layout     LinearLayout inner    LinearLayout  linearLayout findViewById R id inner linear ractionbar       inner setMinimumWidth getWidth     2   10          we will set our textview to center and display there some text     TextView t    TextView  linearLayout findViewById R id center text       t setWidth getWidth     6   10         Button b    Button  linearLayout findViewById R id edit button       b setWidth getWidth    3  20        ImageButton imageButton    ImageButton  linearLayout findViewById R id action bar delete item       imageButton setMinimumWidth deviceUtils getWidth     20     and here is getWidth   method    public int getWidth          DisplayMetrics dm   new DisplayMetrics         mActivity getWindowManager   getDefaultDisplay   getMetrics dm       return dm widthPixels

solution is based on these things    you need to use your own class that extends Toolbar  support v7 widget toolbar   you need to override one method Toolbar addView   what does it do    when first time toolbar is executing  setTitle  it creates AppCompatTextView and uses it to display title text   when the AppCompatTextView is created  toolbar  as ViewGroup   adds it into it s own hierarchy with  addView method   also  while trying to find solution i noticed that the textview has layout width set to  wrap content   so i decided to make it  match parent  and assign textalignment to  center     MyToolbar kt  skipping unrelated stuff  constructors imports    class MyToolbar   Toolbar      override fun addView child  View  params  ViewGroup LayoutParams        if  child is TextView            params width   ViewGroup LayoutParams MATCH PARENT         child textAlignment  View TEXT ALIGNMENT CENTER           super addView child  params          possible  side effects  - this will apply to  subtitle  too

You can create a custom layout and apply it to the actionBar   To do so  follow those 2 simple steps     Java Code  getSupportActionBar   setDisplayOptions ActionBar DISPLAY SHOW CUSTOM   getSupportActionBar   setCustomView R layout actionbar      Where R layout actionbar is the following layout    XML   lt  xml version  1 0  encoding  utf-8   gt   lt LinearLayout xmlns android  http   schemas android com apk res android      android layout width  match parent      android layout height  wrap content      android layout gravity  center      android orientation  vertical  gt    lt TextView     android layout width  wrap content      android layout height  wrap content      android layout gravity  center      android id    id action bar title      android text  YOUR ACTIVITY TITLE      android textColor   ffffff      android textSize  24sp    gt   lt  LinearLayout gt     It can be as complex as you want  Try it out   EDIT   To set the background you can use the property android background in the container layout  LinearLayout in that case   You may need to set the layout height android layout height to match parent instead of wrap content    Moreover  you can also add a LOGO   ICON to it  To do so  simply add an ImageView inside your layout  and set layout orientation property android orientation to horizontal  or simply use a RelativeLayout and manage it by yourself    To change the title of above custom action bar dynamically  do this    TextView title  TextView findViewById getResources   getIdentifier  action bar title    id   getPackageName      title setText  Your Text Here
