如何在 Android 中隐藏状态栏

Question

I referred this link . In that if the user clicks on EditText(for ex To: ) at that time keyboard will be popped out and at the same time the user can be able to scroll to see all remaining views(ex: compose,subject, send button) in that screen. Similarly in my app I have one activity in that I am having some widgets or views. Suppose if the user clicks on Edittext which is in my Activity then keyboard is popping out and i can be able to scroll to see remaining views. But if i give this attribute android:theme="@android:style/Theme.NoTitleBar.Fullscreen" in manifest i was unable to scroll to see remaining views but if give attribute android:theme="@android:style/Theme.NoTitleBar" like this in manifest I can be able to scroll to see remaining view but there is status bar in that screen, here I want full screen and even if the keyboard is popped out I can scroll to see remaining views..? what changes I have to made for this..?

Answer 1

Write this in your Activity

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

Check Doc here : https://developer.android.com/training/system-ui/status.html

and your app will go fullscreen. no status bar, no title bar. :)

Answer 2

Use theme "Theme.NoTitleBar.Fullscreen" and try setting "android:windowSoftInputMode=adjustResize" for the activity in AndroidManifest.xml. You can find details here .

Answer 3

 if (Build.VERSION.SDK_INT < 16) {
   getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
 } else {
     View decorView = getWindow().getDecorView();
      int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
      decorView.setSystemUiVisibility(uiOptions);
      ActionBar actionBar = getActionBar();
      actionBar.hide();
 }

Answer 4

使用此代码在您的应用中隐藏状态栏并易于使用

getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

Answer 5

If you need this in one activity, you have to put in onCreate, before setContentView:

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

setContentView(R.layout.your_screen);

Answer 6

Add this to your Activity class

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    this.getWindow().setFlags(
                        WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                        WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.activity_main);
    // some your code
}

Answer 7

Use this for your Activity .

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

Answer 8

If you are hiding the status bar do this in onCreate(for Activity) and onCreateView/onViewCreated(for Fragment)

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

And don't forget to clear the flag when exiting the activity or else you will have the full screen in your whole app after visiting this activity. To clear do this in your onDestroy(for Activity) or onDestroyView(for Fragment)

getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)

Answer 9

在manifest.xml文件中更改应用程序的主题。

android:theme="@android:style/Theme.Translucent.NoTitleBar"

Answer 10

void hideStatusBar() {
        if (Build.VERSION.SDK_INT < 16) {
           getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
        } else {
            View decorView = getWindow().getDecorView();
            int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
            decorView.setSystemUiVisibility(uiOptions);
        }
    }

You can use this method to hide the status bar. And this is important to hide the action bar too. In this case, you can getSupportActionBar().hide() if you have extended the activity from support lib like Appcompat or you can simply call getActionBar().hide() after the method mentioned above. Thanks

Answer 11

Use this code:

requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
super.onCreate(savedInstanceState);
setContentView(R.layout.youractivityxmlname);

Answer 12

In AndroidManifest.xml -> inside the activity which you want to use, add the following:

android:theme="@style/Theme.AppCompat.Light.NoActionBar"
//this is for hiding action bar

and in MainActivity.java -> inside onCreate() method, add the following :

this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
//this is for hiding status bar

Answer 13

This code hides status bar.

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

to hide action bar write this line:-

requestWindowFeature(Window.FEATURE_NO_TITLE);

both lines can be written collectively to hide Action bar and status bar. all these lines must be written before setContentView method call in onCreate method.

Answer 14

You can hide by using styles.xml

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>
<style name="HiddenTitleTheme" parent="AppTheme">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
</style>

just call this in your manifest like this android:theme="@style/HiddenTitleTheme"

Answer 15

As FLAG_FULLSCREEN is deprecated from android R. You can use below code to hide status bar.

 @Suppress("DEPRECATION")
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {

           window.insetsController?.hide(WindowInsets.Type.statusBars())
    } else {

           window.setFlags(
                    WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN
            )
        }

Answer 16

You can hide status bar by setting it's color to transperant using xml . Add statusBarColor item to your activity theme:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>

Answer 17

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setTheme(R.style.Theme_AppCompat_Light_NoActionBar);
    requestWindowFeature(Window.FEATURE_NO_TITLE);

    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN
    , WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.activity__splash_screen);
}

Answer 18

this is the best solution for me , just write this line in your theme.xml

<style name="MyApp" parent="Theme.AppCompat.Light.NoActionBar">
...
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
...
</style>

Answer 19

This is the official documentation about hiding the Status Bar on Android 4.0 and lower and on Android 4.1 and higher

Please, take a look at it:

https://developer.android.com/training/system-ui/status.html

Answer 20

Hide StatusBar

private void hideSystemBars() {
    WindowCompat.setDecorFitsSystemWindows(getWindow(), false);
    WindowInsetsControllerCompat windowInsetsController = ViewCompat.getWindowInsetsController(getWindow().getDecorView());
    if (windowInsetsController == null) {
        return;
    }
    // Configure the behavior of the hidden system bars
    windowInsetsController.setSystemBarsBehavior(WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);
    // Hide both the status bar and the navigation bar
    windowInsetsController.hide(WindowInsetsCompat.Type.systemBars());
}

show StatusBar

private void showSystemBars() {
    WindowCompat.setDecorFitsSystemWindows(getWindow(), false);
    WindowInsetsControllerCompat windowInsetsController = ViewCompat.getWindowInsetsController(getWindow().getDecorView());
    if (windowInsetsController == null) {
        return;
    }
    // Configure the behavior of the hidden system bars
    windowInsetsController.setSystemBarsBehavior(WindowInsetsControllerCompat.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE);
    // Hide both the status bar and the navigation bar
    windowInsetsController.show(WindowInsetsCompat.Type.systemBars());
}

for top camera cut with screen

<item name="android:windowLayoutInDisplayCutoutMode" tools:ignore="NewApi">shortEdges</item>

Answer 21

We cannot prevent the status appearing in full screen mode in (4.4+) kitkat or above devices, so try a hack to block the status bar from expanding.

Solution is pretty big, so here's the link of SO:

StackOverflow : Hide status bar in android 4.4+ or kitkat with Fullscreen

Answer 22

This solution work for me :)

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (Build.VERSION.SDK_INT >= 19) {
           getWindow().setFlags(AccessibilityNodeInfoCompat.ACTION_NEXT_HTML_ELEMENT, AccessibilityNodeInfoCompat.ACTION_NEXT_HTML_ELEMENT);
           getWindow().getDecorView().setSystemUiVisibility(3328);
    }else{
           requestWindowFeature(Window.FEATURE_NO_TITLE);
           this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }

    DataBindingUtil.setContentView(this, R.layout.activity_hse_video_details);

Answer 23

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // If the Android version is lower than Jellybean, use this call to hide
    // the status bar.
    if (Build.VERSION.SDK_INT < 16) {
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
    } else {
       View decorView = getWindow().getDecorView();
       // Hide the status bar.
       int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
       decorView.setSystemUiVisibility(uiOptions);
       // Remember that you should never show the action bar if the
       // status bar is hidden, so hide that too if necessary.
       ActionBar actionBar = getActionBar();
       actionBar.hide();
    }

    setContentView(R.layout.activity_main);

}
...
}

Answer 24

在Manifest

android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen"

Answer 25

If you refer to the Google Documents you can use this method for android 4.1 and above, call this method before setContentView()

public void hideStatusBar() {
    View view = getWindow().getDecorView();
    int uiOption = View.SYSTEM_UI_FLAG_FULLSCREEN;
    view.setSystemUiVisibility(uiOption);
    ActionBar actionBar = getActionBar();
    if (actionBar != null) {
        actionBar.hide();
    }
}

Answer 26

including android api 30, this works for me

if (Build.VERSION.SDK_INT < 16) {
        window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)
    } else if (Build.VERSION.SDK_INT < 30) {
        window.decorView?.systemUiVisibility = View.SYSTEM_UI_FLAG_FULLSCREEN
        actionBar?.hide()
    } else {
        window.decorView.windowInsetsController?.hide(WindowInsets.Type.statusBars())
    }

Answer 27

在 Style.xml 文件中添加或替换

<item name="android:statusBarColor">@android:color/transparent</item>

Answer 28

We can hide status bar in Android 4.1 (API level 16) and higher by using setSystemUiVisibility()

window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_FULLSCREEN

As per google document we should never show the action bar if the status bar is hidden, so hide that too if necessary.

actionBar?.hide()

Answer 29

I know I'm very late to answer. I use the following piece of code in a relative java file for this purpose

Objects.requireNonNull(getSupportActionBar()).hide();

Answer 30

If you are working with higher API then you may have noticed the flags as mentioned by the above answers ie FLAG_FULLSCREEN and SYSTEM_UI_FLAG_FULLSCREEN are deprecated, at least in java.

To cover up the whole screen you can define a custom theme:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="ActivityTheme" parent="Theme.AppCompat.NoActionBar">
        <item name="android:windowFullscreen">true</item>
    </style>
</resources>

Add the theme in your activity in the manifest like android:theme="@style/ActivityTheme" and you are done.

Note : You can also add pre-defined @android themes directly in your manifest: android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen" . In such cases make sure your activity extends Activity() not AppCompatActivity() .

Answer 31

If you are using Compose then you can import

implementation "com.google.accompanist:accompanist-systemuicontroller:0.17.0"

then in your screen just write

val systemUiController = rememberSystemUiController()
systemUiController.isStatusBarVisible = false

Answer 32

The clean and scalable approach to show and hide system UI I stick to, which works for different Android Api levels:

object SystemBarsCompat {
    private val api: Api =
        when {
            Build.VERSION.SDK_INT >= Build.VERSION_CODES.S -> Api31()
            Build.VERSION.SDK_INT == Build.VERSION_CODES.R -> Api30()
            else -> Api()
        }

    fun hideSystemBars(window: Window, view: View, isImmersiveStickyMode: Boolean = false) =
        api.hideSystemBars(window, view, isImmersiveStickyMode)

    fun showSystemBars(window: Window, view: View) = api.showSystemBars(window, view)

    fun areSystemBarsHidden(view: View): Boolean = api.areSystemBarsHidden(view)

    @Suppress("DEPRECATION")
    private open class Api {
        open fun hideSystemBars(window: Window, view: View, isImmersiveStickyMode: Boolean = false) {
            val flags = View.SYSTEM_UI_FLAG_FULLSCREEN or
                View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION or
                View.SYSTEM_UI_FLAG_HIDE_NAVIGATION

            view.systemUiVisibility = if (isImmersiveStickyMode) {
                flags or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            } else {
                flags or
                    View.SYSTEM_UI_FLAG_IMMERSIVE or
                    View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            }
        }

        open fun showSystemBars(window: Window, view: View) {
            view.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
        }

        open fun areSystemBarsHidden(view: View) = view.systemUiVisibility and View.SYSTEM_UI_FLAG_HIDE_NAVIGATION != 0
    }

    @Suppress("DEPRECATION")
    @RequiresApi(Build.VERSION_CODES.R)
    private open class Api30 : Api() {

        open val defaultSystemBarsBehavior = WindowInsetsController.BEHAVIOR_SHOW_BARS_BY_SWIPE

        override fun hideSystemBars(window: Window, view: View, isImmersiveStickyMode: Boolean) {
            window.setDecorFitsSystemWindows(false)
            view.windowInsetsController?.let {
                it.systemBarsBehavior =
                    if (isImmersiveStickyMode) WindowInsetsController.BEHAVIOR_SHOW_TRANSIENT_BARS_BY_SWIPE
                    else defaultSystemBarsBehavior
                it.hide(WindowInsets.Type.systemBars())
            }
        }

        override fun showSystemBars(window: Window, view: View) {
            window.setDecorFitsSystemWindows(false)
            view.windowInsetsController?.show(WindowInsets.Type.systemBars())
        }

        override fun areSystemBarsHidden(view: View) = !view.rootWindowInsets.isVisible(WindowInsets.Type.navigationBars())
    }

    @RequiresApi(Build.VERSION_CODES.S)
    private class Api31 : Api30() {
        override val defaultSystemBarsBehavior = WindowInsetsController.BEHAVIOR_DEFAULT
    }
}

Answer 33

Here How you can hide the status bar Use this function in your Helper Object Class and call it in your activity

    fun hideStatusBar(window: Window, context: Context){
    if (SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        window
            .decorView
            .systemUiVisibility =
            View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
                    View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
        window.statusBarColor = ContextCompat.getColor(context, R.color.transparent_bg_color)
    } else {
        window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)
    }
}

Call it in your Activity before set Content View.

hideStatusBar(window, this)
setContentView(R.layout.activity_detail)

Answer 34

Try below. This worked for me.

In your manifest, add the below theme.

<activity
   android:theme="@style/Theme.YourAppName.ActivityFullscreenNoCutout"
   android:name=".MainActivity"
   android:exported="true">
   <intent-filter>
      <action android:name="android.intent.action.MAIN" />
      <category android:name="android.intent.category.LAUNCHER" />
   </intent-filter>
</activity>

Then in your styles XML add the below code.

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools">
    <style name="Theme.YourAppName.ActivityFullscreenNoCutout">
        <item name="android:windowLayoutInDisplayCutoutMode" tools:ignore="NewApi">shortEdges</item>
    </style>
</resources>

After that in your MainActivity add the following codes.

public class MainActivity extends AppCompatActivity {

    private int currentApiVersion;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

        currentApiVersion = Build.VERSION.SDK_INT;
        final int flags =
                View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
                        View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY;
        if (currentApiVersion >= Build.VERSION_CODES.KITKAT) {
            getWindow().getDecorView().setSystemUiVisibility(flags);
            final View decorView = getWindow().getDecorView();
            decorView.setOnSystemUiVisibilityChangeListener(visibility -> {
                if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
                    decorView.setSystemUiVisibility(flags);
                }
            });
        }
    }

    @SuppressLint("NewApi")
    @Override
    public void onWindowFocusChanged(boolean hasFocus) {
        super.onWindowFocusChanged(hasFocus);
        if (currentApiVersion >= Build.VERSION_CODES.KITKAT && hasFocus) {
            getWindow().getDecorView().setSystemUiVisibility(
                    View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION |
                            View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
        }
    }

}

Answer 35

Under res -> values ->styles.xml

Inside the style body tag paste

<item name="android:windowTranslucentStatus" tools:targetApi="kitkat">true</item>

Answer 36

requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
