Android Remove Title method

In the actual application development, we sometimes need to set the Activity to display the full screen, in general, there are two ways to set the screen display effect:

One: Setcontentview before code oncreate (below)
View plaincopy to Clipboardprint?
   public void OnCreate (Bundle savedinstancestate) {
                      super.oncreate (savedinstancestate);
                     //title
        &NB Sp             requestwindowfeature (window.feature_no_title);
                     //cancel status bar
        &NB Sp           GetWindow (). SetFlags (WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
                    Setcontentview (R.layout.main);
     }

However, it is important to note that in the code settings, set untitled and set the full screen of the two code to be placed in the Setcontentview (r.layout.main) (interface rendering, complete the full screen is not possible) before the code. Otherwise you will get an error.

Second: Set in the manifest configuration file

The first of these methods
① Create a Theme.xml file in the Res/values directory (used to put styles)

<?xml version= "1.0" encoding= "Utf-8"?>
<resources>
<!--names is the name of the style, and parent inherits that parent style--
<style name= "Theme_fullscreen" parent= "Android:Theme.Black" >
<item name= "Android:windownotitle" >true</item> <!--set Untitled-
<item name= "Android:windowfullscreen" >?android:windowNoTitle</item>

<!--are you populating the slow screen, referencing the value of Android:windownotitle? android:windownotitle, depending on the value of Android:windownotitle--
</style>
</resources>

②<activity android:name= ". Login. Loginactivity "Android:theme=" @style/theme_fullscreen "/>

Second method

<?xml version= "1.0" encoding= "Utf-8"?>
<manifest xmlns:android= "/http/ Schemas.android.com/apk/res/android "
package=" Com.andyidea "
android:versioncode=" 1 "
Android: Versionname= "1.0" >
<uses-sdk android:minsdkversion= "8"/>
<application android:icon= "@drawable/ Icon "android:label=" @string/app_name ">
<activity android:name=". Login. Loginactivity "
Android:theme=" @android: Style/theme.notitlebar.fullscreen "
android:label=" @string/app_ Name >
<intent-filter>
<action android:name= "Android.intent.action.MAIN"/>
<category Android:name= "Android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</ Application>
</manifest>

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= "Theme_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/theme_notitle" >
This can also be achieved by removing the title bar effect
