Android: status bar not theme on transitiong to new activity

Question

I have create a simple app with 2 activities. Main (launcher) activity is themed properly where colorPrimaryDark is applied to status bar. But when I transition to new activity, everything seems normal except status bar. It somehow colored white. Any idea why this could be happening?

Running this on OnePlus One (Lollipop 5.0.2)

Target api -> 16+

values/styles.xml

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/PrimaryColor</item>
    <item name="colorPrimaryDark">@color/PrimaryDarkColor</item>
    <item name="colorAccent">@color/accent</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

values-v21/styles.xml

<style name="AppTheme" parent="AppTheme.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/slide_bottom</item>
    <item name="android:windowSharedElementExitTransition">@android:transition/move</item>
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>

layout/activity_settings.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#856"
    android:fitsSystemWindows="true"
    android:orientation="vertical"
    tools:context=".SettingsActivity">

</LinearLayout>

Answer 1

Change

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

to

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

Answer 2

Change the api level to 11+, you can find it. change the Theme to DarkActionBar

Answer 3

In values-v21/styles.xml, change

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

to

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

Answer 4

You might be not needing this anymore but I recently get this issue so maybe this will help others.

I fix it by creating new style in values-v21/styles.xml extending from the AppTheme:

<style name="AppTheme.SolidStatusBar">
    <item name="android:statusBarColor">@color/PrimaryDarkColor</item>
</style>

and use this as your new Activity theme in manifest. This way your changes don't have to interfere with activities that need to use translucent status bar like your Main activity.

I have no idea why is this happening though.
