Five ways to hide status bar and title bar on Android

Five ways to hide status bar and title bar on Android

Method 1:

public class MainActivity extends Activity 
{ 
 
  @Override 
  protected void onCreate(Bundle savedInstanceState) 
  { 
    (savedInstanceState); 
 
    // Hide the title bar    requestWindowFeature(Window.FEATURE_NO_TITLE); 
    // Hide the status bar    getWindow().setFlags(.FLAG_FULLSCREEN, 
        .FLAG_FULLSCREEN); 
 
    setContentView(.activity_main); 
  } 
 
}

Method 2:


<!-- Hide the status bar and title bar at the same time  -->  
<activity 
  android:name="" 
  android:theme="@android:style/" 
  android:label="@string/app_name" > 
  <intent-filter> 
    <action android:name="" /> 
 
 
    <category android:name="" /> 
  </intent-filter> 
</activity>

Method 3:

<!-- Application theme. --> 
<style name="AppTheme" parent="AppBaseTheme"> 
  <!-- All customizations that are NOT specific to a particular API-level can go here. --> 
  <!-- Hide status bar --> 
  <item name="android:windowFullscreen">true</item> 
  <!-- Hide title bar --> 
  <item name="android:windowNoTitle">true</item> 
</style>

Method 4: Dynamically display the hidden status bar

//Hide status bar  lp = ().getAttributes(); 
  |= .FLAG_FULLSCREEN; 
 ().setAttributes(lp); 

//Show the status bar   attr = ().getAttributes(); 
   &= (~.FLAG_FULLSCREEN); 
  ().setAttributes(attr);

Method 5: Dynamically display the hidden status bar

The View class provides setSystemUiVisability and getSystemUiVisability methods, which implement dynamic display or hidden operations on the status bar, and obtain the current visibility of the status bar.

Analysis of the actual parameters passed in the setSystemUiVisibility method:

The actual parameters that can be passed in by the setSystemUiVisability(int visibility) method are:

1. View.SYSTEM_UI_FLAG_VISIBLE: Display the status bar,
Activity does not display in full screen (restore to normal state).
2. : Hide the status bar, and the Activity will be displayed in full screen.
3. View.SYSTEM_UI_FLAG_FULLSCREEN: Activity is displayed in full screen, and the status bar is hidden and overwritten.
4. View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN: Activity is displayed in full screen, but the status bar will not be hidden and overwritten, the status bar is still visible, and the top layout part of the Activity will be obscured by the status.
5. View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION: The effect is the same as View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
6. View.SYSTEM_UI_LAYOUT_FLAGS: The effect is the same as View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
7. View.SYSTEM_UI_FLAG_HIDE_NAVIGATION: Hide virtual buttons (navigation bar). Some phones use virtual buttons instead of physical buttons.
8. View.SYSTEM_UI_FLAG_LOW_PROFILE: The status bar display is in a low profile mode, and some icons on the status bar will be hidden.
