I have created an app with Jetpack compose and expected the start up background is black or some other colors, not white. This is my themes.xml
<style name="Theme.AlluringScreenshot" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
<item name="android:statusBarColor">#030318</item>
<item name="android:windowBackground">#030318</item>
</style>
The above style works well till on Android 11 but Android 12. My app still has white background at starting up. Any suggestions for this matter?
Use the splash screen API as a placeholder while jetpack compose is still processing
This is the author of this question.
After spending more time diving into some documents, I have found the spot for this matter. It looks very simple than any the solutions I found.
The android:windowBackground attribute only work till Android 11. This should be replaced by android:windowSplashScreenBackground to work well on Android 12.
That's all.
There must be some conflicting declaration.
Import material 3
implementation 'androidx.compose.material3:material3:1.1.0-alpha02'
implementation 'com.google.android.material:material:1.8.0-alpha02'
use in parent for the activity theme:
<style name="AppTheme" parent="Theme.Material3.DayNight.NoActionBar">
...
</style>
create a composable wrapper for the theme in Theme.kt for compose:
import androidx.compose.foundation.isSystemInDarkTheme
import androidx.compose.material3.MaterialTheme
import androidx.compose.material3.Typography
import androidx.compose.material3.darkColorScheme
import androidx.compose.material3.lightColorScheme
#Composable
fun AppTheme(
darkTheme: Boolean = isSystemInDarkTheme(),
content: #Composable () -> Unit
) {
MaterialTheme(
colorScheme = when (darkTheme) {
true -> darkColorScheme()
else -> lightColorScheme()
},
typography = Typography(),
content = content
)
}
and then wrap your composable screens with :
AppTheme{
MyComposableScreen()
}
if you have to change colors do it in darkColorScheme() nad lightColorScheme(), if it is not enough then change the xml attributes
I'm following the theming tutorial from developer.google. I'm trying to migrate the app to Mat. 3 and modify the status bar's color to match with the background color.
After adding android:statusBarColor and android:windowLightStatusBar, nothing changes.
I noticed that at the very first moments the app loading, status bar is really as my expected, but a moment later it becomes wrong.
Before: https://i.stack.imgur.com/i43cL.png
After: https://i.stack.imgur.com/kMwaP.png
What I've tried:
// res/values/themes.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.Superheroes" parent="android:Theme.Material.Light.NoActionBar">
<item name="android:statusBarColor">#color/background_light</item>
<item name="android:windowLightStatusBar">true</item>
<item name="android:windowBackground">#color/background_light</item>
</style>
</resources>
// res/values-night/themes.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.Superheroes" parent="android:Theme.Material.NoActionBar">
<item name="android:statusBarColor">#color/background_dark</item>
<item name="android:windowLightStatusBar">false</item>
<item name="android:windowBackground">#color/background_dark</item>
</style>
</resources>
In Jetpack Compose the easiest is to use the Accompanist System UI Controller.
Add this to your dependencies : implementation "com.google.accompanist:accompanist-systemuicontroller:0.27.0"
Then, in your MainActivity:
setContent {
MyTheme {
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colorScheme.background
) {
val systemUiController = rememberSystemUiController()
SideEffect {
systemUiController.setStatusBarColor(
color = Color(0xff655D8A),
)
}
}
}
}
Source and details here.
The compose samples project Jetchat does this through xml themes.
Be sure to cover all android versions as they do in the various themes.xml files in the same way they do or you'll end up with some weird behaviour on specific versions.
Another way to change it without adding a dependency is at ui.theme/Theme.kt as #2801938 has mentioned:
#Composable
fun YourAppTheme(darkTheme...) {
...
val view = LocalView.current
if (!view.isInEditMode) {
SideEffect {
val window = (view.context as Activity).window
window.statusBarColor = colorScheme.primary.toArgb()
WindowCompat.getInsetsController(window, view).isAppearanceLightStatusBars = darkTheme
}
}
...
}
I'm trying to have both the NavigationBar and the StatusBar as transparent and then use windowInsets to adapt my Views.
I'm now able to have a transparent NavigationBar that correctly applies windowInsets, but I can't change the StatusBar color. I've tried every combination I've found online, but the only one that is working is using FLAG_LAYOUT_NO_LIMITS, which cause the windowInset to return 0 for the systemWindowInsetBottom (and this isn't good because I'm using a BottomAppBar).
While the StatusBar is solid white, windowInset.systemWindowInsetTop return the right amount of pixels and the views are correctly layed out, but when I scroll the RecyclerView it disappears behind the StatusBar.
This is my current setup, I really need a different set of eyes to spot the bug.
MainActivity
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setWindowBehindSystemBars()
colorizeStatusBar()
setContentView(R.layout.activity_main)
}
private fun setWindowBehindSystemBars() {
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
}
private fun colorizeStatusBar() {
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
window.statusBarColor = ContextCompat.getColor(this, R.color.transparent)
}
Theme
<style name="BaseTheme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
<!-- other attributes, all related to color -->
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:navigationBarColor">#color/transparent</item>
</style>
EDIT:
I tried setting android:windowBackground to blue and when the application opens I can see the blue behind the StatusBar for a brief moment, so I think something is setting the color back to white after that.
I need to make transparent status bar. I am using getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS) and it is make status bar as I want. But it also affect navigation bar: it became transparent and getWindow().setNavigationBarColor(Color.BLACK) do nothing.
Is there way to make transparent status bar only and not navigation bar?
this work for me
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
)
styles.xml
<style name="TranslucentStatusBar" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowTranslucentStatus">true</item>
</style>
v21\styles.xml
<style name="TranslucentStatusBar" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
<item name="android:windowTranslucentStatus">true</item>
</style>
status bar will be transparent or translucent, navigation bar won't
hope this helps!
using mikepenz's comment
what I exactly working code (converted to kotlin) below here.
// at AppCompatActivity, min SDK is 16, I tested api 25
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
}
if (Build.VERSION.SDK_INT >= 19) {
window.decorView.systemUiVisibility =
View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}
if (Build.VERSION.SDK_INT >= 21) {
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
window.statusBarColor = Color.TRANSPARENT
}
setContentView(R.layout.activity_main)
}
Scroll down to check how the end result looks like
First of all, define your styles.xml something like this-
styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
</style>
DO NOT add the following line
<item name="android:windowTranslucentStatus">true</item>
Adding above line will NOT shift the layout up when the soft keyboard is shown on a Dialog with an EditText
Then override this style in v21 and v23 styles like this-
v21/styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
</style>
v23/styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
</style>
Activity code - Kotlin
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
window.setFlags(
LayoutParams.FLAG_LAYOUT_NO_LIMITS,
LayoutParams.FLAG_LAYOUT_NO_LIMITS
)
setContentView(R.layout.YOUR_LAYOUT_RESOURCE_ID)
.
.
.
}
Activity code - Java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(
LayoutParams.FLAG_LAYOUT_NO_LIMITS,
LayoutParams.FLAG_LAYOUT_NO_LIMITS
)
setContentView(R.layout.YOUR_LAYOUT_RESOURCE_ID)
.
.
.
}
End result
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
fun showTransparentStatusbar() {
activity!!.window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN)
}
fun removeStatusbarFlags() {
activity!!.window.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN)
}
Try this and wont regret it
window.decorView.systemUiVisibility = (
View.SYSTEM_UI_FLAG_LAYOUT_STABLE or
View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
)
You can use like this
to hide status bar and navigation bar
WindowManager.LayoutParams attributes = getWindow().getAttributes();
attributes.flags |= WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS;
getWindow().setAttributes(attributes);
and for showing the navigationBar again use this
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION, WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
}
the color is grey for me, maybe you can force it to your primary color
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
Just flag above worked for me. Navigation buttons are visible, status bar and action bar are hidden.
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
Is not working. Test device nexus 5.
i found the solution bro
<style name="transparent" parent="Theme.AppCompat.Light.NoActionBar">//AppCompat is the key; You can choose any other theme than the light-theme, but stick to AppCompat
<item name="android:windowTranslucentStatus">false</item>
<item name="android:windowDrawsSystemBarBackgrounds">false</item>
//Other styling(optional)
</style>
and then apply this transparent theme to your activity manifest like this
<activity
...
android:theme="#style/transparent"/>
For all those interested in workarounds/hacks because Android API concerning this matter is just awful. Do not use any system window flags, set negative margin to the root of your layout, and then use setStatusBarColor to make your StatusBar transparent.
statusBarHeight = getResources().getDimensionPixelSize(R.dimen.margin_24dp);
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId != 0) {
statusBarHeight = getResources().getDimensionPixelSize(resourceId);
}
FrameLayout.LayoutParams rootParams = (FrameLayout.LayoutParams) binding.getRoot().getLayoutParams();
rootParams.topMargin = -statusBarHeight;
binding.getRoot().setLayoutParams(rootParams);
getWindow().setStatusBarColor(getResources().getColor(R.color.transparent));
where binding.getRoot() is of course the root of your layout
and result is
yes , You can use this code in Style.xml
<style name="transparent" parent="Theme.AppCompat.Light">//AppCompat is the key; You can choose any other theme than the light-theme, but stick to AppCompat
<item name="colorPrimaryDark">#00000000</item>//THIS is the important part.
//Other styling(optional)
</style>
Then to apply it to your layout, simply add the following line in the root layout(view):
android:theme="#style/transparent"
getWindow().setFlags(
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS,
WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS
)
<style name="TranslucentStatusBar" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowTranslucentStatus">true</item>
</style>
This works on Samsung S10+ (Pie), Oppo F7 and Oppo F5S (Oreos):
getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_OVERSCAN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
As asked by the original poster, the app area is expanded on top and covers the status bar (where the clock is). But the android navigation (virtual) buttons remains at the bottom of the screen and the app sits on top of the android buttons.
I have set my statusBar color to transparent for Lollipop only with the following line in my theme :
<item name="android:statusBarColor">#android:color/transparent</item>
Now I need to draw behind it, but I can't get any view draw behind it. I know how to do it with the windowTranslucentStatus property, but don't want to use this property since it will then ignore the color of the statusBar set to transparent.
Method #1:
To achieve a completely transparent status bar, you have to use statusBarColor, which is only available on API 21 and above. windowTranslucentStatus is available on API 19 and above, but it adds a tinted background for the status bar. However, setting windowTranslucentStatus does achieve one thing that changing statusBarColor to transparent does not: it sets the SYSTEM_UI_FLAG_LAYOUT_STABLE
and SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN flags. The easiest way to get the same effect is to manually set these flags, which effectively disables the insets imposed by the Android layout system and leaves you to fend for yourself.
You call this line in your onCreate method:
getWindow().getDecorView().setSystemUiVisibility(
View.SYSTEM_UI_FLAG_LAYOUT_STABLE
| View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
Be sure to also set the transparency in /res/values-v21/styles.xml:
<item name="android:statusBarColor">#android:color/transparent</item>
Or set the transparency programmatically:
getWindow().setStatusBarColor(Color.TRANSPARENT);
The good side to this approach is that the same layouts and designs can also be used on API 19 by trading out the transparent status bar for the tinted translucent status bar.
<item name="android:windowTranslucentStatus">true</item>
Method #2:
If you only need to paint a background image under your status bar, instead of positioning a view behind it, this can be done by simply setting the background of your activity's theme to the desired image and setting the status bar transparency as shown in method #1. This was the method I used to create the screenshots for the Android Police article from a few months ago.
Method #3:
If you've got to ignore the standard system insets for some layouts while keeping them working in others, the only viable way to do it is to work with the often linked ScrimInsetsFrameLayout class. Of course, some of the things done in that class aren't necessary for all scenarios. For example, if you don't plan to use the synthetic status bar overlay, simply comment out everything in the init() method and don't bother adding anything to the attrs.xml file. I've seen this approach work, but I think you'll find that it brings some other implications that may be a lot of work to get around.
I also saw that you're opposed to wrapping multiple layouts. In the case of wrapping one layout inside of another, where both have match_parent for height and width, the performance implications are too trivial to worry about. Regardless, you can avoid that situation entirely by changing the class it extends from FrameLayout to any other type of Layout class you like. It will work just fine.
This worked for my case
// Create/Set toolbar as actionbar
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Check if the version of Android is Lollipop or higher
if (Build.VERSION.SDK_INT >= 21) {
// Set the status bar to dark-semi-transparentish
getWindow().setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,
WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
// Set paddingTop of toolbar to height of status bar.
// Fixes statusbar covers toolbar issue
toolbar.setPadding(0, getStatusBarHeight(), 0, 0);
}
// A method to find height of the status bar
public int getStatusBarHeight() {
int result = 0;
int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
result = getResources().getDimensionPixelSize(resourceId);
}
return result;
}
For more information about working with statusBars: youtube.com/watch?v=_mGDMVRO3iE
Try this theme
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="colorPrimaryDark">#android:color/transparent</item>
<item name="colorPrimary">#color/md_blue_200</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
<item name="android:windowTranslucentStatus">true</item>
</style>
Be sure that, your layout set
android:fitsSystemWindows="false"
Instead of
<item name="android:statusBarColor">#android:color/transparent</item>
Use the following:
<item name="android:windowTranslucentStatus">true</item>
And make sure to remove the top padding (which is added by default) on your 'MainActivity' layout.
Note that this does not make the status bar fully transparent, and there will still be a "faded black" overlay over your status bar.
The solution from Cody Toombs almost did the trick for me. I'm not sure if this is Xamarin related or not, but I now have an acceptable solution:
This is my setup:
I have an Android project where I have referenced the Android.Support v4 and v7 packages. I have two styles defined:
values/styles.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<resources>
<style name="MyStyle" parent="#style/Theme.AppCompat.Light.NoActionBar">
<item name="android:windowTranslucentStatus">true</item>
</style>
</resources>
values-v21/styles.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<resources>
<style name="MyStyle" parent="#style/Theme.AppCompat.Light.NoActionBar">
<item name="android:statusBarColor">#android:color/transparent</item>
</style>
</resources>
AndroidManifest targets "MyStyle":
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="1" android:versionName="1.0" package="com.agn.test.test">
<uses-sdk android:minSdkVersion="10" />
<application android:allowBackup="true" android:icon="#mipmap/icon" android:label="#string/app_name" android:theme="#style/MyStyle">
</application>
</manifest>
And finally the code in the Main Activity:
[Activity (Label = "Test", MainLauncher = true, Icon = "#mipmap/icon")]
public class MainActivity : Activity
{
protected override void OnCreate (Bundle savedInstanceState)
{
base.OnCreate (savedInstanceState);
SetContentView (Resource.Layout.Main);
//Resource.Layout.Main is just a regular layout, no additional flags. Make sure there is something in there like an imageView, so that you can see the overlay.
var uiOptions = (int)Window.DecorView.SystemUiVisibility;
uiOptions ^= (int)SystemUiFlags.LayoutStable;
uiOptions ^= (int)SystemUiFlags.LayoutFullscreen;
Window.DecorView.SystemUiVisibility = (StatusBarVisibility)uiOptions;
Window.AddFlags (WindowManagerFlags.DrawsSystemBarBackgrounds);
}
}
Notice that I set DrawsSystemBarBackgrounds flag, this makes all the difference
Window.AddFlags (WindowManagerFlags.DrawsSystemBarBackgrounds);
I spent a lot of time getting it right, too much time in fact. Hopefully this answer helps anyone trying to achieve the same thing.
#Cody Toombs's answer lead to an issue that brings the layout behind the navigation bar. So what I found is using this solution given by #Kriti
here is the Kotlin code snippet for the same:
if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true)
}
if (Build.VERSION.SDK_INT >= 19) {
window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}
if (Build.VERSION.SDK_INT >= 21) {
setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false)
getWindow().setStatusBarColor(Color.TRANSPARENT)
}
private fun setWindowFlag(activity: Activity, bits: Int, on: Boolean) {
val win: Window = activity.getWindow()
val winParams: WindowManager.LayoutParams = win.getAttributes()
if (on) {
winParams.flags = winParams.flags or bits
} else {
winParams.flags = winParams.flags and bits.inv()
}
win.setAttributes(winParams)
}
You also need to add
android:fitsSystemWindows="false"
root view of your layout.
I had the same problem so i create ImageView that draw behind status bar API 19+
Set custom image behind Status Bar gist.github.com
public static void setTransparent(Activity activity, int imageRes) {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
return;
}
// set flags
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION);
activity.getWindow().setStatusBarColor(Color.TRANSPARENT);
} else {
activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
}
// get root content of system window
//ViewGroup rootView = (ViewGroup) ((ViewGroup) activity.findViewById(android.R.id.content)).getChildAt(0);
// rootView.setFitsSystemWindows(true);
// rootView.setClipToPadding(true);
ViewGroup contentView = (ViewGroup) activity.findViewById(android.R.id.content);
if (contentView.getChildCount() > 1) {
contentView.removeViewAt(1);
}
// get status bar height
int res = activity.getResources().getIdentifier("status_bar_height", "dimen", "android");
int height = 0;
if (res != 0)
height = activity.getResources().getDimensionPixelSize(res);
// create new imageview and set resource id
ImageView image = new ImageView(activity);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, height);
image.setLayoutParams(params);
image.setImageResource(imageRes);
image.setScaleType(ScaleType.MATRIX);
// add image view to content view
contentView.addView(image);
// rootView.setFitsSystemWindows(true);
}
You can use ScrimInsetFrameLayout
https://github.com/google/iosched/blob/master/android/src/main/java/com/google/samples/apps/iosched/ui/widget/ScrimInsetsFrameLayout.java
android:fitsSystemWindows="true" should set on scrim layout!
I will be adding some more information here. The latest Android developments have made it pretty easy to handle a lot of cases in status bar. Following are my observations from the styles.xml
Background color: for SDK 21+, as a lot of answers mentioned,<item name="android:windowTranslucentStatus">true</item> will make the status bar transparent and show in front of UI. Your Activity will take the whole space of the top.
Background color: again,for SDK 21+, <item name="android:statusBarColor">#color/your_color</item> will simply give a color to your status bar, without affecting anything else.
However, in later devices (Android M/+), the icons started coming in different shades. The OS can give a darker shade of gray to the icons for SDK 23/+ , if you override your styles.xml file in values-23 folder and add <item name="android:windowLightStatusBar">true</item>.
This way, you will be providing your user with a more visible status bar, if your status bar has a light color( think of how a lot of google apps have light background yet the icons are visible there in a greyish color).
I would suggest you to use this, if you are giving color to your status bar via point #2
In the most recent devices, SDK 29/+ comes with a system wide light and dark theme, controllable by the user. As devs, we are also supposed to override our style file in a new values-night folder, to give user 2 different experiences.
Here again, I have found the point #2 to be effective in providing the "background color to status bar". But system was not changing the color of status bar icons for my app. since my day version of style consisted of lighter theme, this means that users will suffer from low visibility ( white icons on lighter background)
This problem can be solved by using the point #3 approach or by overriding style file in values-29 folder and using a newer api <item name="android:enforceStatusBarContrast">true</item> . This will automatically enforce the grayish tint to icons, if your background color is too light.
With Android Studio 1.4, the template project with boiler plate code sets Overlay theme on your AppbarLayout and/or Toolbar. They are also set to be rendered behind the status bar by fitSystemWindow attribute = true. This will cause only toolbar to be rendered directly below the status bar and everything else will rendered beneath the toolbar. So the solutions provided above won't work on their own. You will have to make the following changes.
Remove the Overlay theme or change it to non overlay theme for the toolbar.
Put the following code in your styles-21.xml file.
#android:color/transparent
Assign this theme to the activity containing the navigation drawer in
the AndroidManifest.xml file.
This will make the Navigation drawer to render behind the transparent status bar.
Similar to some of the solutions posted, but in my case I did the status bar transparent and fix the position of the action bar with some negative margin
if (Build.VERSION.SDK_INT >= 21) {
getWindow().setStatusBarColor(Color.TRANSPARENT);
FrameLayout.LayoutParams lp = (FrameLayout.LayoutParams) toolbar.getLayoutParams();
lp.setMargins(0, -getStatusBarHeight(), 0, 0);
}
And I used in the toolbar and the root view
android:fitsSystemWindows="true"
There is good library StatusBarUtil from #laobie that help to easily draw image in the StatusBar.
Just add in your build.gradle:
compile 'com.jaeger.statusbarutil:library:1.4.0'
Then in the Activity set
StatusBarUtil.setTranslucentForImageView(Activity activity, int statusBarAlpha, View viewNeedOffset)
In the layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
android:orientation="vertical">

app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<!-- Your layout code -->
</android.support.design.widget.CoordinatorLayout>
</RelativeLayout>
For more info download demo or clone from github page and play with all feature.
Note: Support KitKat and above.
Hope that helps somebody else!
All you need to do is set these properties in your theme
<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>
The accepted answer worked for me using a CollapsingToolbarLayout. It's important to note though, that setSytstemUiVisibility() overrides any previous calls to that function. So if you're using that function somewhere else for the same view, you need to include the View.SYSTEM_UI_FLAG_LAYOUT_STABLE and View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN flags, or they will be overridden with the new call.
This was the case for me, and once I added the two flags to the other place I was making a call to setSystemUiVisibility(), the accepted answer worked perfectly.
Here is the theme I use to accomplish this:
<style name="AppTheme" parent="#android:style/Theme.NoTitleBar">
<!-- Default Background Screen -->
<item name="android:background">#color/default_blue</item>
<item name="android:windowTranslucentStatus">true</item>
</style>
The Right solution is to Change a property in XML under your Activity tag to below style. It just works
