Status Bar Color not showing - 5.0 Lollipop Android Studio: (AppCompat-v7:r21)

Status Bar Color not showing - 5.0 Lollipop Android Studio: (AppCompat-v7:r21)

提问by Adifyr

I'm using the AppCompat-v7:21.0.0support library for Android 5.0 Lollipop in Android Studio. My problem is that the Status Bar Color that can be changed by setting colorPrimaryDarkin the values/styles.xmlfile, is showing up as black, in both the xml layout preview and the emulator.

So what's wrong? Am I missing something? Please let me know. Thanks.

EDIT:I'm aware of the fact that changing the status bar color on Pre-Lollipop versions is not possible. My XML Layout Editor Preview and my Emulator are both set to API Level 21 (5.0 Lollipop). But, the status bar still isn't of the color I set it to in colorPrimaryDark. I tried doing statusBarColorin styles.xmlbut to no avail. It's still black.

ALSO:I saw one of the answers on a similar question where they advised me to put my minSdkVersionto 21. I tried that, but it didn't work. And I want my app to run on devices with API Level 15 and above.

Did you set the target SDK version to 21? I had the same issue when I left the target SDK version to 19. You can leave the min SDK to anything lower.

And of course you need to inherit from the proper theme and make sure your Activity uses it.

Check if you are editing styles.xmlin values-v21folder. If you set SDK version to 21then it won't look for styles.xmlin valuesfolder(but it should do so).

Changing the Status Bar color in pre-Lollipop(5.0) is not possible by setting colorPrimaryDark. See this article.

On older platforms, AppCompat emulates the color theming where possible. At the moment this is limited to coloring the action bar and some widgets.

In my case, the culprit was jfeinstein10/SlidingMenulibrary. I replaced the library with Android navigation drawerand now it displays status bar color correctly.
