Android: Three ways to get rid of title bar and three ways to fullscreen
The first type: A method commonly used when getting started
Add the following code to the OnCreate function:
Requestwindowfeature (window.feature_no_title);//Remove the 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 you can see, the entire application will get rid of the title bar, and if you just 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, which is to create a new Style.xml file under the Res/values directory for example:
<?xml version= "1.0" encoding= "UTF-8"?>
<resources>
<style name= "Notitle" >
<item name= "Android:windownotitle" >true</item>
</style>
</resources>
In this way, we customize a style, which is the equivalent of a topic, and then define it in the Androidmanifest.xml file.
<application android:icon= "@drawable/icon"
Android:label= "@string/app_name"
Android:theme= "@style/notitle" >
Three a summary of the method of removing the title bar first, sometimes we will see that the title bar will appear first, and then disappear, because we are only in the activity of the OnCreate method defined, the second relative to the first is better, will not appear this situation, the third I personally feel the best, This separates the functions and facilitates maintenance and expansion.
Android developed three ways to get rid of the title bar and recommend a third
