If you re using AppCompat  declare your activity in AndroidManifest xml as follows    lt activity     android name   SomeActivity              android theme   style Theme AppCompat Light NoActionBar    gt

Put this line in your Activity in the Manifest   lt activity android name  quot  MainActivity quot          android theme  quot  style Theme AppCompat Light NoActionBar quot  gt                   lt  activity gt   and make sure you didn t put Toolbar in your layout   lt androidx appcompat widget Toolbar             android id  quot   id toolbar quot              android layout width  quot match parent quot              android layout height  quot  attr actionBarSize quot                gt

If you want most of your activities to have an action bar you would probably inherit your base theme from the default one  this is automatically generated by Android Studio per default     lt  -- Base application theme  -- gt       lt style name  AppTheme  parent  Theme AppCompat Light DarkActionBar  gt           lt  -- Customize your theme here  -- gt           lt item name  colorPrimary  gt  color colorPrimary lt  item gt           lt item name  colorPrimaryDark  gt  color colorPrimaryDark lt  item gt           lt item name  colorAccent  gt  color colorAccent lt  item gt       lt  style gt    And then add a special theme for your bar-less activity    lt style name  AppTheme NoTitle  parent  AppTheme  gt           lt item name  windowNoTitle  gt true lt  item gt           lt item name  windowActionBar  gt false lt  item gt           lt item name  actionBarTheme  gt  null lt  item gt       lt  style gt    For me  setting actionBarTheme to  null was the solution   Finally setup the activity in your manifest file    lt activity     android theme   style AppTheme NoTitle       gt

You may also change inheritance from ActionBarActivity to Activity as written here   UPDATE  A good solution is here    Override protected void onCreate Bundle savedInstanceState        getWindow   requestFeature Window FEATURE ACTION BAR       super onCreate savedInstanceState       getSupportActionBar   hide        setContentView R layout activity main

There are multiple ways of doing this  1  Change the theme in Android Manifest Below the Application element  you will find theme tag  Replace it with this one - android theme  quot  android style Theme NoTitleBar quot   If you are using AppCompat  use  android style Theme AppCompat NoActionBar  This will set the theme for all activities  If you don t need the action bar in a specific acitivity  then set the theme in the activity container  ie  lt activity android theme  quot  android style Theme NoTitleBar quot      gt   You may also set android theme  quot  android style Theme NoTitleBar quot  theme in the styles and use it later on   2  Create a Custom Theme Add this in res values styles xml  lt style name  quot NoActionBar quot  parent  quot  android style Theme Holo Light quot  gt        lt item name  quot windowActionBar quot  gt false lt  item gt        lt item name  quot android windowNoTitle quot  gt true lt  item gt   lt  style gt   and then set it as your activity s theme in Manifest   lt activity android theme  quot  style NoActionBar quot        gt    3  Dynamically Remove the Action Bar Put this code in the onCreate method before setting content view - getWindow   requestFeature Window FEATURE ACTION BAR   getActionBar   hide     If you are using the support library use getSupportActionBar

Please find the default theme in styles xml   lt  -- Base application theme  -- gt       lt style name  AppTheme  parent  Theme AppCompat Light DarkActionBar  gt           lt  -- Customize your theme here  -- gt           lt item name  colorPrimary  gt  color colorPrimary lt  item gt           lt item name  colorPrimaryDark  gt  color colorPrimaryDark lt  item gt           lt item name  colorAccent  gt  color colorAccent lt  item gt       lt  style gt    And change parent this way    lt style name  AppTheme  parent  Theme AppCompat Light NoActionBar  gt

Haha  I have been stuck at that point a while ago as well  so I am glad I can help you out with a solution  that worked for me at least     What you want to do is define a new style within values styles xml so it looks like this   lt resources gt       lt style name    AppTheme  parent    android Theme Holo Light DarkActionBar  gt           lt  -- Customize your theme here  -- gt       lt  style gt        lt style name    NoActionBar  parent     android style Theme Holo Light  gt           lt item name    android windowActionBar  gt false lt  item gt           lt item name    android windowNoTitle  gt true lt  item gt       lt  style gt    lt  resources gt    Only the NoActionBar style is intresting for you  At last you have to set is as your application s theme in the AndroidManifest xml so it looks like this   lt application     android allowBackup    true      android icon     drawable ic launcher      android label     string app name      android theme     style NoActionBar     lt  --This is the important line-- gt       gt       lt activity             I hope this helps  if not  let me know

Considering everyone is posting older ways of hiding the ActionBar here is the proper way of implementing it within styles for AppCompat support library  Which I highly suggest moving toward if you haven t already    Simply removing the ActionBar   lt style name  AppTheme  parent  Theme AppCompat Light NoActionBar  gt   lt  style gt    If you are using the appcompat support libraries  this is the easiest and recommended way of hiding the ActionBar to make full screen or start implementing to toolbar within your layouts    lt style name  AppTheme  parent  Theme AppCompat Light NoActionBar  gt       lt  -- Your Toolbar Color-- gt       lt item name  colorPrimary  gt  color primary lt  item gt        lt  -- colorPrimaryDark is used for the status bar -- gt       lt item name  colorPrimaryDark  gt  color primary dark lt  item gt        lt  -- colorAccent is used as the default value for colorControlActivated       which is used to tint widgets -- gt       lt item name  colorAccent  gt  color accent lt  item gt        lt  -- You can also set colorControlNormal  colorControlActivated      colorControlHighlight  and colorSwitchThumbNormal  -- gt   lt  style gt    Then to change your toolbar color   lt android support v7 widget Toolbar     android id      id my awesome toolbar        android layout height    wrap content        android layout width    match parent        android minHeight     attr actionBarSize        android background     attr primary      gt    Last note  Your Activity class should extend AppCompatActivity  public class MainActivity extends AppCompatActivity     lt  --Activity Items -- gt
