How to hide the title bar for an Activity in XML

Question

I want to hide the title bar 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 for to much activities. Can I set a no title style item somewhere?

Answer 1

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);

this refers to the Activity.

Answer 2

ahem you can apply themes to individual activities in xml such as no title. In other words take it out of your application tag open tag declaration and put it in the desired activity tag

Answer 3

I now did the following.

I declared a style inheriting everything from my general style and then disabling the titleBar.

<style name="generalnotitle" parent="general">
    <item name="android:windowNoTitle">true</item>
</style>

Now I can set this style to every Activity in which I want to hide the title bar overwriting the application wide style and inheriting all the other style informations, therefor no duplication in the style code.

You can modify your AndroidManifest.xml:

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

Yuo can use this for each activity in your project.
