Generally, there are three ways to set the full screen display of Android applications
The first is code implementation
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //Setting without Title requestWindowFeature(Window.FEATURE_NO_TITLE); //Setting the full screen of the application must be written before the setContentView method! ! ! Remember! getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.activity_main);
The second is to configure in the AndroidManifest, xml manifest configuration file and
add attributes to the nodes in the corresponding Activity: android:theme="@android:style/Theme.NoTitleBar.Fullscreen" to set an Activity to display in full screen. If it is set to android:theme="@android:style/Theme.NoTitleBar", it is just set to the untitled state.
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
The third method is to customize the full-screen Theme
and define the theme in the style.xml file (if there is no style.xml, create it in the res/values directory) and then directly add android:theme
to the Activity attribute that needs full-screen display in AndroidManifest.xml
= "@style/Theme.NoTitle_FullScree"
