How to hide the title bar for an Activity in XML with existing custom theme
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 for to much activities.
Can I set a no title style item somewhere?
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 .
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 .
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">
