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?

Answer 1

You can modify your AndroidManifest.xml:

<activity android:name=".MainActivity"           android:label="@string/app_name"           android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen"> 

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.

Answer 2

Do this in your onCreate() method.

//Remove title bar this.requestWindowFeature(Window.FEATURE_NO_TITLE);  //Remove notification bar this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);  //set content view AFTER ABOVE sequence (to avoid crash) this.setContentView(R.layout.your_layout_name_here);  

this refers to the Activity.
