[android] Lollipop : draw behind statusBar with its color set to transparent

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.

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"

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>

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.

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">

    <ImageView
        android:layout_alignParentTop="true"
        android:layout_width="match_parent"
        android:adjustViewBounds="true"
        android:layout_height="wrap_content"
        android:src="@drawable/toolbar_bg"/>

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/view_need_offset"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="@android:color/transparent"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>

        <!-- Your layout code -->
    </android.support.design.widget.CoordinatorLayout>
</RelativeLayout>

Note: Support KitKat and above.

Hope that helps somebody else!

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;
}

The Right solution is to Change a property in XML under your Activity tag to below style. It just works

  android:theme="@style/Theme.AppCompat.Light.NoActionBar"

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.

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.

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"

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);

}

@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.

All you need to do is set these properties in your theme

<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>

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

1. 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.

2. 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.

3. 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

4. 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.

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.

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!
