Android - Making activity full screen with status bar on top of it

I want to make my activity full screen with status bar on top of it like this picture:
I have used this code in manifest inside activity tag:
'android:theme="#style/Theme.AppCompat.Light.NoActionBar"'
But my view doesn't start from the status bar & it looks like this:
How can I make my activity look like the first one?

I know that the guy asking the question may have found his own solution but for the people who are still looking for a solution this is a very simple solution but one thing it has a limitation till Kitkat so a condition is added
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}

Add these to your Base Application Theme in styles.xml
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
And add following attribute to your parent layout:
android:fitsSystemWindows="false"
Hope this helps.

If you dont want your "Translucent navigation" transparent, here is the code to just make transparent the status bar
In your theme:
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowTranslucentStatus">true</item>
In your activity onCreate:
Window window = getWindow();
WindowManager.LayoutParams winParams = window.getAttributes();
winParams.flags &= ~WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS;
window.setAttributes(winParams);
window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

1. Transparent Statusbar
window?.decorView?.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)
window.statusBarColor = Color.TRANSPARENT
2. Transparent Statusbar & Bottomnav bar
window.setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN
);
3. Hide Statusbar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
window.insetsController?.hide(WindowInsets.Type.statusBars())
}
else {
#Suppress("DEPRECATION")
window.setFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN
)
}
4. Hide Statubar & Bottomnav bar
val actionBar: ActionBar? = supportActionBar
if (actionBar != null) actionBar.hide()
window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LOW_PROFILE
or View.SYSTEM_UI_FLAG_FULLSCREEN
or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION)
where to put this code ?
override fun onCreate(savedInstanceState: Bundle?) {
/* Put above code here ..... */
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_slider)
}
Note
I checked this code in Pixel 3A emulator
Maybe customise android OS not support
set styel <style name="Theme.FullScreen" parent="Theme.MaterialComponents.DayNight.NoActionBar">

To achieve something similar to this, use this:
1. Your Activity Theme
<style name="FullScreenTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
<item name="android:windowTranslucentNavigation">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:windowActivityTransitions">true</item>
</style>
2. There is NO NEED to add android:fitsSystemWindows property into your root layout XML file.
3. In your Activity
Add padding top to your toolbar. I am using custom toolbar, so I am adding padding to my toolbar of the height of statusbar.
toolbar.setPadding(0, getStatusBarHeight(), 0, 0)
and the function getStatusBarHeight() is added in my Utils class
fun Activity.getStatusBarHeight(): Int {
val resourceId = resources.getIdentifier("status_bar_height", "dimen", "android")
return if (resourceId > 0) resources.getDimensionPixelSize(resourceId)
else Rect().apply { window.decorView.getWindowVisibleDisplayFrame(this) }.top
}

put below of code inside onCreate()
private void setStatusBarTransparent() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
View decorView = window.getDecorView();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
} else {
decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}
window.setStatusBarColor(Color.TRANSPARENT);
}
}

Try Like This
<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>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
Hope this one will help

In Kotlin just use following code in your activity, also add android:fitsSystemWindows="true" in your parent view of activity.xml layout file.
This will also show content over navigation bar too, provided you declared full screen style in your style.xml
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
window.setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
)
}

you can use this code after onCreate
setTheme(android.R.style.Theme_Black_NoTitleBar_Fullscreen);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
if (getSupportActionBar() != null) {
getSupportActionBar().hide();
}
your activity will be fullscrean with status bar :)

#tahsinRupam answer is correct and tested on post Kitkat version.
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
If you want to use it only for a certain activity, create a style, and attach it on your manifest style like this.
<activity
android:name=".MainActivity"
android:screenOrientation="portrait"
android:theme="#style/Activity.Fullscreen.Theme" />
<style name="Activity.Fullscreen.Theme" parent="MyMaterialTheme.Base">
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
</style>
Thumbs up on origal #tahsinRupam
Happy codings Cheers !

Put this code in your Activity onCreate this will hide the status bar
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();

Can't change color of status bar

I am trying to theme my app to follow the material Android look. My project is a Xamarin.Android project, which targets API 23, but the minimum API target is 16. So I have to use the AppCompat library to have the same design on all APIs.
I have followed these guides: Material Theme,Beautiful Material Design with the Android Support Design Library,Android Tips: Hello AppCompatActivity, Goodbye ActionBarActivity and created these files:
Resources/values/styles.xml:
<resources>
<style name="MyTheme" parent="MyTheme.Base">
</style>
<style name="MyTheme.Base" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#F44336</item>
<item name="colorPrimaryDark">#D32F2F</item>
<item name="colorAccent">#FF4081</item>
</style>
</resources>
Resources/values-v21/styles.xml
<resources>
<!--
Base application theme for API 21+. This theme replaces
MyTheme from resources/values/styles.xml on API 21+ devices.
-->
<style name="MyTheme" parent="MyTheme.Base">
<item name="android:windowContentTransitions">true</item>
<item name="android:windowAllowEnterTransitionOverlap">true</item>
<item name="android:windowAllowReturnTransitionOverlap">true</item>
<item name="android:windowSharedElementEnterTransition">#android:transition/move</item>
<item name="android:windowSharedElementExitTransition">#android:transition/move</item>
</style>
</resources>
MainActivity.cs
using Android.App;
using Android.Widget;
using Android.OS;
using Android.Support.V7.App;
namespace TestThemeApp
{
[Activity(Label = "TestThemeApp", MainLauncher = true, Icon = "#drawable/icon", Theme = "#style/MyTheme")]
public class MainActivity : AppCompatActivity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
}
}
}
I'm just trying to make the the toolbar red, and the status bar a darker red, but the status bar color won't change. This is what it looks like:
What did I do wrong?

Try this in your style (Resources/values-v21/styles.xml)
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
>
<item name="android:statusBarColor">#color/cobalt_light</item>
I personaly prefer to handle it in the onCreate method of the activity:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(getResources().getColor(R.color.gray_very_dark));
window.setNavigationBarColor(getResources().getColor(R.color.gray_darker));
}

For a simple workaround you can change your primary color to the desired color of your status bar and it will change the color of your status bar automatically.
NOTE: It is a work around till you find the correct answer.

You'll have to add a flag at the top of the MainActivity and set the bar color at the end.
public class MainActivity : AppCompatActivity
{
protected override void OnCreate(Bundle bundle)
{
// First check if the current SDK is >= 21. Else it will cause trouble
if ((int)Build.VERSION.SdkInt >= 21)
Window.AddFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
SetBarColor();
}
public void SetBarColor ()
{
if((int)Build.VERSION.SdkInt >= 21)
Window.SetStatusBarColor(Color.ParseColor("#FF0000"));
}
}

Use below code snippet to change statusbar color:
public void setStatusBarColor(Activity context, int color) {
if (Build.VERSION.SDK_INT >= 21) {
Window window = context.getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.setStatusBarColor(ContextCompat.getColor(context,color));
}
}

I think that i have found the most elegant solution based on the other answers:
The only thing i changed was added the flag in the OnCreate(Bundle bundle) function:
protected override void OnCreate(Bundle bundle)
{
if ((int)Build.VERSION.SdkInt >= (int)BuildVersionCodes.Lollipop)
Window.AddFlags(Android.Views.WindowManagerFlags.DrawsSystemBarBackgrounds);
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
}
And that's it! The style files do the rest, and on older version of android, the status bar just won't change.

Change background color of android action bar at runtime

I'm trying to change the background color of android action bar at runtime, according to an image VibrantColor.
I found some references, but neither worked for me.
Change action bar color in android
How do I change the background color of the ActionBar of an ActionBarActivity using XML?
I have this code to get the color from the image, and it works.
public int getImageColor(Bitmap foto) {
Palette palette = Palette.generate(foto);
List<Palette.Swatch> swatchList = palette.getSwatches();
int maiorPopulação = 0;
int color = 0;
for (Palette.Swatch sw : swatchList){
if (sw.getPopulation() > maiorPopulação) {
maiorPopulação = sw.getPopulation();
color = sw.getRgb();
}
}
return palette.getVibrantColor(color);
}
Then I try to set the returned color to the ActionBar:
public static void alteraCor(Fragment fragmento, int color) {
ActionBarActivity atividade = (ActionBarActivity)fragmento.getActivity();
android.support.v7.app.ActionBar actionBar = atividade.getSupportActionBar();
if ( fragmento instanceof Detalhes )
actionBar.setBackgroundDrawable(new ColorDrawable(Color.rgb(
Color.red(color),
Color.green(color),
Color.blue(color)
)));
else
actionBar.setBackgroundDrawable(new ColorDrawable(fragmento.getResources().getColor(R.color.fundoEscuro)));
}
I called alteraCor from onCreate and from onAttach on Fragment, but neither of them worked.
EDIT:
I use the folowing Style:
<style name="VendasFacil" parent="#style/Theme.AppCompat">
<item name="android:textColor">#color/Fonte</item>
<item name="android:background">#color/fundoPrimeiroPlano</item>
<item name="android:windowBackground">#color/fundoPrimeiroPlano</item>
<item name="actionBarTheme">#style/VendasFacil.ActionBar</item>
<item name="android:actionBarTheme" tools:ignore="NewApi">#style/VendasFacil.ActionBar</item>
</style>
<style name="VendasFacil.ActionBar" parent="#style/Widget.AppCompat.ActionBar">
<item name="android:background">#color/fundoEscuro</item>
<item name="android:displayOptions">showHome|homeAsUp|showTitle</item>
<item name="displayOptions">showHome|homeAsUp|showTitle</item>
<item name="android:homeAsUpIndicator">#drawable/ic_launcher</item>
<item name="homeAsUpIndicator">#drawable/ic_drawer</item>
</style>
I do not have the color I want to use as background previously to put it in a style file. It is as if the color was defined by the user at runtime.

You will need to create a style for that. You can then change the style at runtime to have the actionbar reflect it.
This might be useful: http://developer.android.com/guide/topics/ui/actionbar.html#AdvancedStyles
Here is an example of a style changing the actionbar color:
<style name="MyActionBar" parent="#android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">ANY_HEX_COLOR_CODE</item>
</style>

You can use Android Action Bar Style Generator . It's generate XML files. Copy to your project. It's easy and nice.

Hey there appears to be a small bug in your code:
actionBar.setBackgroundDrawable(new ColorDrawable(Color.rgb(
Color.red(color),
Color.green(color),
Color.blue(color)
)));
Your are setting the r the g and the b value to the hex value of the color. What you need to do instead is simply:
actionBar.setBackgroundDrawable(new ColorDrawable(color));

Android Material: Status bar color won't change

I'm developing an simple app to test the material design. I'm using com.android.support:appcompat-v7:21.0.0 and my activity looks like:
public class MyActivity extends ActionBarActivity {
...
}
The layout is defined as:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MyActivity">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="128dp"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimaryDark"/>
</LinearLayout>
Now i defined my theme following material guidelines:
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<item name="colorPrimary">#color/colorPrimary500</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark700</item>
</style>
I'd like to change the status bar color in pre Android 5 and set it to colorPrimaryDark but i can't find the way. I tried using:
getWindow().setStatusBarColor(..)
but setStatusBar color is available from level 21.
Why if i define a colorPrimaryDark in my theme and use appcompact the status bar doesn't change color?
Anyone can help?

While colouring the status bar is not supported <5.0, on 4.4 you can use a work around to achieve a darker colour:
Make the status bar translucent
<item name="android:windowTranslucentStatus">true</item>
Then use AppCompat's Toolbar for your appbar, making sure that it fits system windows:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
...
android:fitsSystemWindows="true"/>
Make sure to set your toolbar as your activity's toolbar:
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
The toolbar stretches underneath the status bar, and the semi translucency of the status bar makes it appear to be a darker secondary colour. If that's not the colour you want, this combination allows you to fit a view underneath your status bar sporting the background colour of your choice (though it's still tinted darker by the status bar).
Kind of an edge case workaround due to 4.4 only, but there ya go.

The status bar is a system window owned by the operating system. On pre-5.0 Android devices, applications do not have permission to alter its color, so this is not something that the AppCompat library can support for older platform versions. The best AppCompat can do is provide support for coloring the ActionBar and other common UI widgets within the application.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().setStatusBarColor(getResources().getColor(R.color.actionbar));
}
Put this code in your Activity's onCreate method. This helped me.

As others have also mentioned, this can be readily solved by adding the following to the onCreate() of the Activity:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
getWindow().setStatusBarColor(ContextCompat.getColor(this, R.color.primary_dark));
}
However, the important point I want to add here is that in some cases, even the above does not change the status bar color. For example, when using MikePenz library for Navigation Drawer, it implicityly overrides the status bar color, so that you need to manually add the following for it to work:
.withStatusBarColorRes(R.color.status_bar_color)

Status bar coloring is not supported in AppCompat v7:21.0.0.
From the Android developers blog post
On older platforms, AppCompat emulates the color theming where possible. At the moment this is limited to coloring the action bar and some widgets.
This means the AppCompat lib will only color status bars on Lollipop and above.

Switch to AppCompatActivity and add a 25 dp paddingTop on the toolbar and turn on
<item name="android:windowTranslucentStatus">true</item>
Then, the will toolbar go up top the top

This solution sets the statusbar color of Lollipop, Kitkat and some pre Lollipop devices (Samsung and Sony).
The SystemBarTintManager is managing the Kitkat devices ;)

I know this doesn't answer the question, but with Material Design (API 21+) we can change the color of the status bar by adding this line in the theme declaration in styles.xml:
<!-- MAIN THEME -->
<style name="AppTheme" parent="#android:style/Theme.Material.Light">
<item name="android:actionBarStyle">#style/actionBarCustomization</item>
<item name="android:spinnerDropDownItemStyle">#style/mySpinnerDropDownItemStyle</item>
<item name="android:spinnerItemStyle">#style/mySpinnerItemStyle</item>
<item name="android:colorButtonNormal">#color/myDarkBlue</item>
<item name="android:statusBarColor">#color/black</item>
</style>
Notice the android:statusBarColor, where we can define the color, otherwise the default is used.

Make Theme.AppCompat style parent
<style name="AppTheme" parent="Theme.AppCompat">
<item name="android:colorPrimary">#005555</item>
<item name="android:colorPrimaryDark">#003333</item>
</style>
And put getSupportActionBar().getThemedContext() in onCreate().
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
getSupportActionBar().getThemedContext();
}

**
Solution for naughty LOLLIPOP
**
hello i had rly big problem with having that darker than was my color... so this is solution to avoid that shadow behind status bar from solution with TranslucentStatus...
so in all of your java activity you need this:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
and at your styles.xml you need to set background color (this color will be your status bar color):
<style name="AppCompat" parent="Theme.AppCompat">
<item name="android:colorBackground">#color/YOUR_STATUS_BAR_COLOR</item>
</style>
and at all your layouts you need to add layout which will be your background:
<LinearLayout
android:background="#color/YOUR_BACKGROUND_COLOR"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="bottom"
/>
of course if you would like use #color/just name... you need to set that at colors.xml:
<color name="YOUR_STATUS_BAR_COLOR">#cf031c</color>
<color name="YOUR_BACKGROUND_COLOR">#383838</color>
here is whole process how we did done that: Whats the right approach to create or change color of a status bar?

How to change the status bar color in Android?

First of all it's not a duplicate as in How to change the background color of android status bar
How do I change the status bar color which should be same as in navigation bar.
I want the status bar color to be same as the navigation bar color

Android 5.0 Lollipop introduced Material Design theme which automatically colors the status bar based on the colorPrimaryDark value of the theme.
Note by realdognose: with Material Design library it will be colorPrimaryVariant
This is supported on device pre-lollipop thanks to the library support-v7-appcompat starting from version 21. Blogpost about support appcompat v21 from Chris Banes
Read more about the Material Theme on the official Android Developers website

Update:
Lollipop:
public abstract void setStatusBarColor (int color)
Added in API level 21
Android Lollipop brought with it the ability to change the color of status bar in your app for a more immersive user experience and in tune with Google’s Material Design Guidelines.
Here is how you can change the color of the status bar using the new window.setStatusBarColor method introduced in API level 21.
Changing the color of status bar also requires setting two additional flags on the Window; you need to add the FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag and clear the FLAG_TRANSLUCENT_STATUS flag.
Working Code:
import android.view.Window;
...
Window window = activity.getWindow();
// clear FLAG_TRANSLUCENT_STATUS flag:
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
// add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
// finally change the color
window.setStatusBarColor(ContextCompat.getColor(activity,R.color.my_statusbar_color));
Offcial developer reference : setStatusBarColor(int)
Example :material-design-everywhere
Chris Banes Blog- appcompat v21: material design for pre-Lollipop devices!
The transitionName for the view background will be android:status:background.

Place this is your values-v21/styles.xml, to enable this on Lollipop:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#color/color_primary</item>
<item name="colorPrimaryDark">#color/color_secondary</item>
<item name="colorAccent">#color/color_accent</item>
<item name="android:statusBarColor">#color/color_primary</item>
</style>
</resources>

For Java Developers:
As #Niels said you have to place in values-v21/styles.xml:
<item name="android:statusBarColor">#color/black</item>
But add tools:targetApi="lollipop" if you want single styles.xml, like:
<item name="android:statusBarColor" tools:targetApi="lollipop">#color/black</item>
For Kotlin Developers:
window.statusBarColor = ContextCompat.getColor(this, R.color.color_name)

this is very easy way to do this without any Library:
if the OS version is not supported - under kitkat - so nothing happend.
i do this steps:
in my xml i added to the top this View:
<View
android:id="#+id/statusBarBackground"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
then i made this method:
public void setStatusBarColor(View statusBar,int color){
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
//status bar height
int actionBarHeight = getActionBarHeight();
int statusBarHeight = getStatusBarHeight();
//action bar height
statusBar.getLayoutParams().height = actionBarHeight + statusBarHeight;
statusBar.setBackgroundColor(color);
}
}
also you need those both methods to get action Bar & status bar height:
public int getActionBarHeight() {
int actionBarHeight = 0;
TypedValue tv = new TypedValue();
if (getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
{
actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,getResources().getDisplayMetrics());
}
return actionBarHeight;
}
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
then the only thing you need is this line to set status bar color:
setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));

You can use this simple code:
One-liner in Kotlin:
window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)
Original answer with Java & manual version check:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light, this.getTheme()));
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
getWindow().setStatusBarColor(getResources().getColor(R.color.colorAccentDark_light));
}

To change the color for above lolipop just add this to your styles.xml
<item name="android:statusBarColor">#color/statusBarColor</item>
but remember, if you want to have a light color for the status bar, add this line too
<item name="android:windowLightStatusBar">true</item>

Well, Izhar's solution was OK but personally, I try to avoid code that looks as this:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
//Do what you need for this SDK
};
But I don't like to duplicate code either. In your answer I have to add a line of code like below in all Activities:
setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));
So, I took Izhar's solution and used XML to get the same result:
Create a layout for the StatusBar status_bar.xml
<View xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="#dimen/statusBarHeight"
android:background="#color/primaryColorDark"
android:elevation="#dimen/statusBarElevation">
Notice the height and elevation attributes, these will be set in values, values-v19, values-v21 further down.
Add this layout to your activities layout using include, main_activity.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/Black" >
<include layout="#layout/status_bar"/>
<include android:id="#+id/app_bar" layout="#layout/app_bar"/>
//The rest of your layout
</RelativeLayout>
For the Toolbar, add top margin attribute:
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
android:background="#color/primaryColor"
app:theme="#style/MyCustomToolBarTheme"
app:popupTheme="#style/ThemeOverlay.AppCompat.Dark"
android:elevation="#dimen/toolbarElevation"
android:layout_marginTop="#dimen/appBarTopMargin"
android:textDirection="ltr"
android:layoutDirection="ltr">
</android.support.v7.widget.Toolbar>
In your appTheme style-v19.xml and styles-v21.xml, add the windowTranslucent attr:
styles-v19.xml, v21:
<resources>
<item name="android:windowTranslucentStatus">true</item>
</resources>
And finally, on your dimens, dimens-v19, dimens-v21, add the values for the Toolbar topMargin, and the height of the statusBarHeight:
dimens.xml for less than KitKat:
<resources>
<dimen name="toolbarElevation">4dp</dimen>
<dimen name="appBarTopMargin">0dp</dimen>
<dimen name="statusBarHeight">0dp</dimen>
</resources>
The status bar height is always 24dp
dimens-v19.xml for KitKat and above:
<resources>
<dimen name="statusBarHeight">24dp</dimen>
<dimen name="appBarTopMargin">24dp</dimen>
</resources>
dimens-v21.xml for Lolipop, just add the elevation if needed:
<resources>
<dimen name="statusBarElevation">4dp</dimen>
</resources>
This is the result for Jellybean KitKat and Lollipop:

Just create a new theme in res/values/styles.xml where you change the "colorPrimaryDark" which is the color of the status bar:
<style name="AppTheme.GrayStatusBar" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimaryDark">#color/colorGray</item>
</style>
And modify the activity theme in AndroidManifest.xml to the one you want, on the next activity you can change the color back to the original one by selecting the original theme:
<activity
android:name=".LoginActivity"
android:theme="#style/AppTheme.GrayStatusBar" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
This is how your res/values/colors.xml should look like:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#303F9F</color>
<color name="colorAccent">#c6d6f0</color>
<color name="colorGray">#757575</color>
</resources>

You can change the status bar color with this function. works on android L means API 21 and higher and needs a color string such as "#ffffff".
private void changeStatusBarColor(String color){
if (Build.VERSION.SDK_INT >= 21) {
Window window = getWindow();
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.parseColor(color));
}
}

I had this requirement: Changing programmatically the status bar color keeping it transparent, to allow the Navigation Drawer to draw itself overlapping the trasparent status bar.
I cannot do that using the API
getWindow().setStatusBarColor(ContextCompat.getColor(activity ,R.color.my_statusbar_color)
If you check here in stack overflow everyone before that line of code set the transparency of the status bar to solid with
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
I'm able to manage color and transparency of status bar like this:
Android 4: there's not much you can do, because you can't manage status bar color from the API ... the only thing you can do is to set the status bar as translucent and move a colored element of you UI under the status bar. To do this you need to play with
android:fitsSystemWindows="false"
in your main layout. This allows you to draw you layout under the status bar. Then you need to play with some padding with the top of your main layout.
Android 5 and above: you have to define a style with
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
this allows the navigation drawer to overlap the status bar.
Then to change the color keeping the status bar transparent you have to set the status bar color with
drawerLayout.setStatusBarBackgroundColor(ContextCompat.getColor(activity, R.color.my_statusbar_color))
where drawerLayout is defined like this
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

To Change the color of the status bar go to
res/values-v21/styles.xml and color of status bar
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="colorPrimary">#color/color_primary</item>
<item name="colorPrimaryDark">#color/color_secondary</item>
<item name="colorAccent">#color/color_accent</item>
<item name="android:statusBarColor">#0000FF</item>
</style>
</resources>

If you want to change the status bar color programmatically (and provided the device has Android 5.0).
This is a simple way to change statusBarColor from any Activity
and very easy methods when differents fragments have different status bar color.
/**
* #param colorId id of color
* #param isStatusBarFontDark Light or Dark color
*/
fun updateStatusBarColor(#ColorRes colorId: Int, isStatusBarFontDark: Boolean = true) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
val window = window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
window.statusBarColor = ContextCompat.getColor(this, colorId)
setSystemBarTheme(isStatusBarFontDark)
}
}
/** Changes the System Bar Theme. */
#RequiresApi(api = Build.VERSION_CODES.M)
private fun setSystemBarTheme(isStatusBarFontDark: Boolean) {
// Fetch the current flags.
val lFlags = window.decorView.systemUiVisibility
// Update the SystemUiVisibility depending on whether we want a Light or Dark theme.
window.decorView.systemUiVisibility = if (isStatusBarFontDark) lFlags and View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR.inv() else lFlags or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR
}

If you want to work on Android 4.4 and above, try this. I refer to Harpreet's answer and this link. Android and the transparent status bar
First, call setStatusBarColored method in Activity's onCreate method(I put it in a util class). I use a image here, you can change it to use a color.
public static void setStatusBarColored(Activity context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
{
Window w = context.getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
int statusBarHeight = getStatusBarHeight(context);
View view = new View(context);
view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
view.getLayoutParams().height = statusBarHeight;
((ViewGroup) w.getDecorView()).addView(view);
view.setBackground(context.getResources().getDrawable(R.drawable.navibg));
}
}
public static int getStatusBarHeight(Activity context) {
int result = 0;
int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = context.getResources().getDimensionPixelSize(resourceId);
}
return result;
}
Before:
After:
The color of the status bar has been changed, but the navi bar is cut off, so we need to set the margin or offset of the navi bar in the onCreate method.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT, (int)(this.getResources().getDimension(R.dimen.navibar_height)));
layoutParams.setMargins(0, Utils.getStatusBarHeight(this), 0, 0);
this.findViewById(R.id.linear_navi).setLayoutParams(layoutParams);
}
Then the status bar will look like this.

Edit the colorPrimary in the colors.xml in Values to the color you want the Status Bar to be. For example:
<resources>
<color name="colorPrimary">#800000</color> // changes the status bar color to Burgundy
<color name="colorPrimaryDark">#303F9F</color>
<color name="colorAccent">#FF4081</color>
<color name="red">#FF0000</color>
<color name="white">#FFFFFF</color>
<color name="cream">#fffdd0</color>
<color name="burgundy">#800000</color>

Solution is very Simple, put the following lines into your style.xml
For dark mode:
<item name="android:windowLightStatusBar">false</item>
<item name="android:statusBarColor">#color/black</item>

Just add these lines in your styles.xml file
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- This is used for statusbar color. -->
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<!-- This is used for statusbar content color. If statusbarColor is light, use "true" otherwise use "false"-->
<item name="android:windowLightStatusBar">false</item>
</style>

This is what worked for me in KitKat and with good results.
public static void setTaskBarColored(Activity context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
{
Window w = context.getWindow();
w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
//status bar height
int statusBarHeight = Utilities.getStatusBarHeight(context);
View view = new View(context);
view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
view.getLayoutParams().height = statusBarHeight;
((ViewGroup) w.getDecorView()).addView(view);
view.setBackgroundColor(context.getResources().getColor(R.color.colorPrimaryTaskBar));
}
}

change the colorPrimaryDark to your desire color into the res/values/styles.xml file
<resources>
<color name="colorPrimary">#800000</color>
<color name="colorPrimaryDark">#303F9F</color> //This Line
<color name="colorAccent">#FF4081</color>
<color name="red">#FF0000</color>
<color name="white">#FFFFFF</color>
<color name="cream">#fffdd0</color>
<color name="burgundy">#800000</color>
</resources>

One more solution:
final View decorView = w.getDecorView();
View view = new View(BaseControllerActivity.this);
final int statusBarHeight = UiUtil.getStatusBarHeight(ContextHolder.get());
view.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, statusBarHeight));
view.setBackgroundColor(colorValue);
((ViewGroup)decorView).addView(view);

This solution only works on API >= 23.
In API level 30 setSystemUiVisibility() has been deprecated. Hence you should use WindowInsetsControllerCompat as follows
fun changeColorStatusBar(color: Int = R.color.white) {
val window: Window = window
val decorView = window.decorView
val wic = WindowInsetsControllerCompat(window, decorView)
wic.isAppearanceLightStatusBars = true
// And then you can set any background color to the status bar.
window.statusBarColor = ContextCompat.getColor(this, color)
}

If you want to set a custom drawable file use this code snippet
fun setCustomStatusBar(){
if (Build.VERSION.SDK_INT >= 21) {
val decor = window.decorView
decor.viewTreeObserver.addOnPreDrawListener(object :
ViewTreeObserver.OnPreDrawListener {
override fun onPreDraw(): Boolean {
decor.viewTreeObserver.removeOnPreDrawListener(this)
val statusBar = decor.findViewById<View>
(android.R.id.statusBarBackground)
statusBar.setBackgroundResource(R.drawable.bg_statusbar)
return true
}
})
}
}

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorPrimaryVariant">#color/colorPrimaryDark</item>
<item name="colorOnPrimary">#color/white</item>
<!-- Secondary brand color. -->
<item name="colorOnSecondary">#color/black</item>
<!-- Status bar color. -->
<item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
<!-- Customize your theme here. -->
</style>
Notice: set colorPrimaryVariant

A very very old question. But for someone who wants to change status bar color from ANDROID 5.0, API 21 & above according to theme Dark and Light even Device DEFAULT.
Put this code in your activity after super.onCreate(savedInstanceState); and before setContentView(R.layout.activity_main);
int currentNightMode = getResources().getConfiguration().uiMode & Configuration.UI_MODE_NIGHT_MASK;
switch (currentNightMode) {
case Configuration.UI_MODE_NIGHT_NO:
// Night mode is not active on device
// For WHITE status bar Icons color to dark
Window window = getWindow();
View view = window.getDecorView();
new WindowInsetsControllerCompat(window, view).setAppearanceLightStatusBars(true);
break;
case Configuration.UI_MODE_NIGHT_YES:
// Night mode is active on device
break;
}
And also in your style.xmlput this line
<item name="android:statusBarColor">#color/colorWhite</item>

Java:
Use this in the onCreate Method of the Activity
Window window = this.getWindow();
window.setStatusBarColor(this.getResources().getColor(R.color.main_screen_bg_color));
Kotlin:
window.statusBarColor = ContextCompat.getColor(this, R.color.colorName)

i used this code to change status bar to transparent
activity?.window?.setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
)
to change it to color in style used this code
i used in fragment in onDetach()
activity?.window?.clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)

Call Method From Activity that you want to change status bar color.
blackIconStatusBar(this, R.color.white);
Method Defination
public static void blackIconStatusBar(Activity activity, int color) {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
activity.getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
activity.getWindow().setStatusBarColor(ContextCompat.getColor(activity, color));
}

In the values/theme.xml, add the item that named name="android:statusBarColor".
<resources xmlns:tools="http://schemas.android.com/tools">
<style name="Theme.YourAppName" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
...
...
...
<!-- Status bar color. -->
<item name="android:statusBarColor" tools:targetApi="l">#color/purple_700</item>
</style>
</resources>

In kotlin I was able to resolve this using the following:
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
window.statusBarColor = ContextCompat.getColor(this, android.R.color.transparent)
