I'm using ActionBarSherlock and I'm trying to hide the title bar of my application but whenever I do that, I get a NullPointerException
when accessing the ActionBar
How do I remove/hide the title bar? Please note that I'm not referring to the title of the action bar. I'm referring to the title bar above the action bar. I'm running my application on an Android 2.3 device.
Below is my code: (My class extends SherlockFragmentActivity
.)
super.onCreate(savedInstanceState);
setTheme(R.style.Theme_Sherlock);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
ActionBar actionbar = getSupportActionBar();
actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); //I get the NullPointerException here.
//...
setContentView(R.layout.tab_navigation);
If you want to hide Action Bar throughout the app (Activities, Fragments) everywhere, you can simply navigate to res > values > styles.
To hide the Title Bar using the Android Manifest. xml file you need to set the Android theme to NoTitleBar like this: android:theme="@android:style/Theme. NoTitleBar">
Another way for removing the title specifically from an activity is by using a getSupportActionBar(). hide() method. Inside the activity's kotlin file, we need to invoke getSupportActionBar(). hide() method.
I hide the title bar by adding the following lines of code:
getSupportActionBar().setDisplayShowTitleEnabled(false);
getSupportActionBar().setDisplayShowHomeEnabled(false);
hope this helps :)
to hide all the title bar and keep only the action bar use this code:
final ActionBar actionBar = getActionBar();
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayUseLogoEnabled(false);
it worked for me
