Status bar turns white and does not show content behind it

问题

I am trying out AppCompat on Marshmallow. And I want to have a transparent status bar however it turns white. I\'ve tried a couple solutions but they didn\'t work for me (Transparent status bar not working with windowTranslucentNavigation="false", Lollipop : draw behind statusBar with its color set to transparent). Here\'s related code.

My styles.xml

<style name=\"Bacon\" parent=\"Theme.Bacon\"/>

<style name=\"Theme.Bacon\" parent=\"Theme.AppCompat.Light.NoActionBar\">
    <item name=\"colorPrimary\">@color/theme_primary</item>
    <item name=\"colorPrimaryDark\">@color/theme_primary_dark</item>
    <item name=\"colorAccent\">@color/theme_accent</item>
    <item name=\"windowActionBar\">false</item>
    <item name=\"windowActionBarOverlay\">true</item>
    <item name=\"windowNoTitle\">true</item>
    <item name=\"android:windowBackground\">@color/background_material_light</item>  
</style>

<style name=\"Theme.Bacon.Detail\" parent=\"Bacon\"/>

v21

<style name=\"Bacon\" parent=\"Theme.Bacon\">
    <item name=\"android:windowDrawsSystemBarBackgrounds\">true</item>
</style>

<style name=\"Theme.Bacon.Detail\" parent=\"Bacon\">
    <item name=\"android:statusBarColor\">@android:color/transparent</item>
</style>

回答1:

I found the answer in this link:Status Bar Color not changing with Relative Layout as root element

So it turns out we need remove the

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

in styles.xml(v21). And it works just fine for me.

(A little late to the party but it might help someone)

I had the exact same problem. Somehow, some activities were normal while new ones I created were showing white status bar instead of colorPrimaryDark value.

After trying several tips, I noticed that the normal-working activities where all using CoordinatorLayout as the root of the layout, while for the others I had replaced it by regular layouts because I didn't need the features (animation, etc) provided by CoordinatorLayout.

So the solution is to make CoordinatorLayout the root layout, and then inside of it add your former layout root. Here is an example:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 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="match_parent"
  android:fitsSystemWindows="true">

  <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <!-- your activity content here-->


  </LinearLayout>
</android.support.design.widget.CoordinatorLayout>

PLEASE NOTE that without android:fitsSystemWindows="true" this solution doesn't work for me.

Tested on Lollipop and Marshmallow

回答3:

 <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@color/colorPrimaryDark</item>
    </style

Just Replace this , statusBarColor should be your expected color and not TRANSPARENT

回答4:

After unsuccessfully trying all of the above I found that explicitly setting the theme fixed the issue.

setTheme(R.style.AppTheme);

That has to go before the super.OnCreate() in your activity.

回答5:

You have to add this property on your style to see the content

<item name="android:windowLightStatusBar" tools:ignore="NewApi">true</item>

回答6:

Add this in your style.xml

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

and this in your onCreate();

 getWindow().getDecorView().setSystemUiVisibility(
       View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

回答7:

Just put this item in your v21\styles.xml :

true

It should look like this :

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:windowTranslucentStatus">true</item>
</style>

回答8:

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

You'll see that line of code in values/styles/styles.xml(v21) . Remove it and that solves the issue

回答9:

I faced the same issue. What i did was, in the "v21/styles.xml" file a changed the value true:

 <item name="android:windowDrawsSystemBarBackgrounds">true</item>

to:

 <item name="android:windowDrawsSystemBarBackgrounds">false</item>

回答10:

I fixed my issue by changing my Activity layout from FrameLayout to RelativeLayout. Thanks everybody who tried to help!

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:background="@android:color/transparent">

    <android.support.v4.view.ViewPager
      android:id="@+id/pager"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="@color/theme_primary_dark"
      android:fitsSystemWindows="true" />

</RelativeLayout>

Try hierarchy-viewer or ViewInspector. These tools might help you.

回答11:

Just remove following tag from style v21 @android:color/transparent

This works for me.

回答12:

Better approach

Check your style.xml file where your NoActionBar theme is there. Make sure its has parent as Theme.AppCompat.NoActionBar and also customize it by adding your color scheme. Finally set your themes in manifest as required.

Below is sample of my styles.xml file (ActionBar + NoActionBar).

<!-- 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>

<!-- No ActionBar application theme. -->
<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.NoActionBar">
    <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>

回答13:

For me it worked by doing the following :

Set the theme .NoActionBar
Wrap the Toolbar in android.support.design.widget.AppBarLayout
Make android.support.design.widget.CoordinatorLayout as the parent layout.

Essentially it is the third step that draws the status bar in the colorPrimaryDark otherwise it is not drawn if you using NoActionBar theme. 2nd step will give your toolbar that overlay.

For styles v23

 <style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowLightStatusBar">true</item>
    <item name="android:statusBarColor">@android:color/white</item>
</style>

For styles v21

<style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:statusBarColor">@android:color/white</item>
</style>

回答15:

[

Expand res -> values -> styles directory from project panel.

Open styles.xml (v21)

USE ANY ONE FROM BELOW WAYS

Change true to false in android:windowDrawsSystemBarBackgrounds property.
Change @android:color/transparent to @color/colorPrimaryDark in android:statusBarColor property.
Remove the android:statusBarColor propert line.

回答16:

If your v21/styles.xml contain

<resources>
    <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
    </style>
</resources>

Then, Remove or comment below line or change colour of status bar,

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

Its working fine. Hope this is helpful. Thanks.

回答17:

I'm not sure if it's late but i hope it helps someone. * Make a fake view with transparent background that fits the layout, and make a coordinatorlayout as your root layout element.

<View
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/transparent"
    android:fitsSystemWindows="true" />


<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    android:scaleType="centerCrop"
    android:src="@drawable/something" />

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

   .... YOUR LAYOUT

回答18:

I have found solution for this -

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:windowLightStatusBar">true</item>
</style>

add this into your style and it will work for api 21 or above.

回答19:

My guess is that this is caused by your android:windowBackground. Is @color/background_material_light a reference to white?

回答20:

Check this Toolbar turns white - AppBar isn't drawn after being scrolled off screen

https://code.google.com/p/android/issues/detail?id=178037#c19

I'm using libraries 23.0.0. and the bug still occurs.

Workaround for this is adding View that takes nearly no space and can be invisible. See the structure below.

<android.support.v4.widget.NestedScrollView
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

</android.support.v4.widget.NestedScrollView>

<android.support.design.widget.AppBarLayout>

    <android.support.v7.widget.Toolbar
        app:layout_scrollFlags="scroll|enterAlways" />

    <android.support.design.widget.TabLayout
        app:layout_scrollFlags="scroll|enterAlways" />

    <View
        android:layout_width="match_parent"
        android:layout_height=".3dp"
        android:visibility="visible"/>

</android.support.design.widget.AppBarLayout>

This Questions on Stackoverflow.com refer to this bug too: CoordinatorLayout Toolbar invisible on enter until full height AppBarLayout - Layout sometimes invisible once it enters view (even if it's not entered)

回答21:

If you are using RelativeLayout / CoordinatorLayout this is the solution that worked for me:

You have to use

CoordinatorLayout
AppBarLayout

Rember to use CoordinatorLayout instead of RelativeLayout (the performance is better and perfectly works with AppBarLayout)

This is how your fragment should starts

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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="match_parent"
android:background="@android:color/background_light"
android:fitsSystemWindows="true"
>

<android.support.design.widget.AppBarLayout
    android:id="@+id/main.appbar"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:fitsSystemWindows="true"
    >
    ...

Good coding!

    Window window = this.getWindow();
    window.setStatusBarColor(this.getResources().getColor(R.color.colorPrimaryDark));
