Full screen or cancel title bar in Android

first introduce the method of removing the title bar: The first type:Also generally used when the introduction of a method Requestwindowfeature (window.feature_no_title);//Remove the title bar note This must be written in front of the Setcontentview () method, or it will be an error The second type:Define <application android:icon= "@drawable/icon" in the Androidmanifest.xml file
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

The third type: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>
<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">

This can also be achieved by removing the title bar effect

Summary of three ways to remove the title bar

First, sometimes we will see that the title bar will appear first, and then disappear, because we are only defined in the activity of the OnCreate method, the second relative to the first is better, do not appear this situation, the third I personally feel the best, so that the function is separate, easy to maintain and expand

to introduce the full-screen method:

First Kind

GetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

The second Kind

Android:theme= "@android: Style/theme.notitlebar.fullscreen"

Third Kind

Application android:icon= "@drawable/icon"
Android:label= "@string/app_name"
Android:theme= "@style/fullscreem"

The third type of customization is stronger, and it is recommended
