如何隐藏具有现有自定义主题的 XML 活动的标题栏

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

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.

To apply the style to a particular Activity, open AndroidManifest.xml and add the following attribute to the activity tag;

<activity
    android:theme="@style/generalnotitle">
