Full screen and remove title bar in Android

the method of removing the title bar
The First: a method that is often used when getting started
requestwindowfeature (window.feature_no_title); // Remove title bar
Note This sentence must be written in front of the Setcontentview () method, or it will be an error
the second type: defined in the Androidmanifest.xml file
<Application Android:icon="@drawable/icon"
Android:label="@string/app_name"
Android:theme = "@android: Style/theme.notitlebar">

As can be seen, the entire application will be removed from the title bar, if you want to remove the title bar of an activity, you can add this attribute to the activity tag


Third: This is not commonly used in general applications, is to create a new Style.xml file under the Res/values directory

For example:

<?XML version= "1.0" encoding= "UTF-8"?>
<Resources>
<stylename= "notitle">
<Itemname= "Android:windownotitle">true</Item>
</style> 
</Resources>

in this way, we customize a style, which is equivalent to a topic, and then defined in the Androidmanifest.xml file, The effect of removing the title bar can also be achieved


<ApplicationAndroid:icon= "@drawable/icon"
Android:label= "@string/app_name"
Android:theme = "@style/notitle">
