How to hide the title bar for an Activity in XML with existing custom theme

Question

I want to hide the titlebar for some of my activities  The problem is that I applied a style to all my activities  therefore I can t simply set the theme to  android style Theme NoTitleBar    Using the NoTitleBar theme as a parent for my style would remove the title bar from all of my activities   Can I set a no title style item somewhere

If you use this requestWindowFeature Window FEATURE NO TITLE  user will still be able to see the title bar just for a moment during launch animation when activity starts through onCreate  If you use  android style Theme Black NoTitleBar as shown below then title bar won t be shown during launch animation    lt activity      android name   MainActivity       android label  My App      android theme   android style Theme Black NoTitleBar      android screenOrientation  portrait  gt    above example will obviously override your existing application theme  if you have existing theme then add  lt item name  android windowNoTitle  gt true lt  item gt  to it

You can modify your AndroidManifest xml    lt activity android name   MainActivity            android label   string app name            android theme   android style Theme Black NoTitleBar Fullscreen  gt    or use android theme   android style Theme Black NoTitleBar  if you don t need a fullscreen Activity    Note  If you ve used a  default  view before  you probably should also change the parent class from AppCompatActivity to Activity

There are mentions of it in this post but no one explicitly addresses it  so maybe this will save people some time  If you are like me and have multiple classes extending one root class which extends ActionBarActivity  it may not be immediately obvious that trying to set that activity to a NoTitleBar NoActionBar will throw an error  specifically    You need to use a Theme AppCompat theme  or descendant  with this activity   You can fix this changing the extends to Activity

the correct answer probably is to not extend ActionbarActivity rather extend  just Activity    if you still use actionbar activity  seems this is working    Override protected void onCreate Bundle savedInstanceState                  super onCreate savedInstanceState       getSupportActionBar   hide       lt  lt  this     setContentView R layout activity main         seems this works too   styles xml       lt style name  AppBaseTheme  parent  Theme AppCompat Light   gt             lt item name  android windowNoTitle  gt true lt  item gt     lt  --   this -- gt           lt  style gt      i could do like as Scott Biggs wrote  this kind of works  except there is no theme then  i mean the settings menu s background is transparent   just change   public class MainActivity extends ActionBarActivity     to Activity or FragmentActivity   public class MainActivity extends Activity        however i could make it look good enough using material design and not remove  the actionbar  https   gist github com shimondoodkin 86e56b3351b704a05e53   set icon of application  set colors of action bar to match design  set icon to settings menu add more icons  buttons on top    it is by example of material design compatibility actionbar styling

Just use getActionBar   hide    in your main activity onCreate   method

I found two reasons why this error might occur   One  The Window flags are set already set inside super onCreate savedInstanceState   in which case you may want to use the following order of commands   this requestWindowFeature Window FEATURE NO TITLE   this getWindow   setFlags WindowManager LayoutParams FLAG FULLSCREEN  WindowManager LayoutParams FLAG FULLSCREEN          super onCreate savedInstanceState     Two  You have the Back Up button inside the TitleBar  meaning that the current activity is a hierarchical child of another activity  in which case you might want to comment out or remove this line of code from inside the onCreate method   getActionBar   setDisplayHomeAsUpEnabled true

Simply change the parent tag of your App theme to  Theme AppCompat Light NoActionBar

You just need to change AppTheme style in Style xml if you replace the definition from DarkActionBar   lt style name  AppTheme  parent  Theme AppCompat Light DarkActionBar  gt    to NoActionBar   lt style name  AppTheme  parent  Theme AppCompat Light NoActionBar  gt    the AppTheme defined in AndroidManifast xml

I don t like the this requestWindowFeature Window FEATURE NO TITLE   because the title bar appears briefly  then disappears    I also don t like the android theme   android style Theme NoTitleBar  because I lost all of the 3 0  Holo changes that the users of the new devices have gotten used to   So I came across this solution   In your res values folder make a file called styles xml  If it doesn t already exist    In that file place the following code    lt resources xmlns android  http   schemas android com apk res android  gt       lt style name  Theme Default  parent   android style Theme  gt  lt  style gt       lt style name  Theme NoTitle  parent   android style Theme NoTitleBar  gt  lt  style gt       lt style name  Theme FullScreen  parent   android style Theme NoTitleBar Fullscreen  gt  lt  style gt   lt  resources gt    Next create a res values-v11 with another styles xml file  Once again this may already exist   In that file place the following code    lt resources xmlns android  http   schemas android com apk res android  gt       lt style name  Theme Default  parent   android style Theme Holo  gt  lt  style gt       lt style name  Theme NoTitle  parent   android style Theme Holo NoActionBar  gt  lt  style gt       lt style name  Theme FullScreen  parent   android style Theme Holo NoActionBar Fullscreen  gt  lt  style gt   lt  resources gt    And if you are targeting 4 0   create a res values-v14 folder with yet another styles xml file  Yes it may already be there    In that file place the following code    lt resources xmlns android  http   schemas android com apk res android  gt       lt style name  Theme Default  parent   android style Theme Holo Light  gt  lt  style gt       lt style name  Theme NoTitle  parent   android style Theme Holo Light NoActionBar  gt  lt  style gt       lt style name  Theme FullScreen  parent   android style Theme Holo Light NoActionBar Fullscreen  gt  lt  style gt   lt  resources gt    Finally  with all of these files created  open your AndroidManifiest xml file you can add the code   android theme   style Theme NoTitle    to the activity tag of the activity you want no title for or the application tag if you want it to apply to the entire application   Now your users will get the themes associated with their device version with the screen layout you desire   P S   Changing the value to android theme   style Theme FullScreen  will have the same effect  but also remove Notification bar
